GEO and sustainable performance: the moderating role of GTD and environmental consciousness

Purpose – Congruent with the world-wide call to combat global warming concerns and advance intellectual capital (IC), organisations are being pressured to ensure that IC is managed effectively to encourage green initiatives. In this regard, green entrepreneurial orientation (GEO) is emerged as a relevant IC. GEO is recognised as a mitigating factor of environmental degradation in the literature. Although prior literature has observed the nexus between GEO and firm performance, the role of GEO in leveraging sustainable performance has been limitedly explored. This study explored the relationship between IC as a GEO and enterprises ’ sustainable performance through the moderating roles of environmental consciousness and green technology dynamism (GTD) in the context of two developing countries (Pakistan and Malaysia). Design/methodology/approach – Data provided by 296 respondents from 264 manufacturing small and medium-sized enterprises (SMEs) in Pakistan and Malaysia were analysed through a three-wave research design. AMOS 23 software was used to perform covariance-based structural equation modelling (CB-SEM), while hierarchical regression analysis was applied using the SPSS 25 software to examine the causal relationships in the model. Findings – IC as a GEO significantly influences sustainable performance, akin to environmental consciousness and GTD. Besides, GTD has a significant moderating effect between GEO and financial and environmental performance in Pakistan and Malaysia but not between GEO and social performance. Environmental consciousnesshas asignificantmoderatingroleinthe impactofGEOonfinancialperformance in Pakistan and Malaysia, but not on social and environmental performance. Practical implications – The study ’ s findings are useful for managers of Pakistani and Malaysian manufacturing SMEs to identify ways to encourage GEO to improve sustainable performance in their firms. The findings suggest that managers should effectively implement GTD and environmental consciousness to strengthen the GEO and sustainable performance relationship. Managers can use GEO concretely as a reference for the


Introduction
Within the world of modern knowledge (Guthrie et al., 1999;Oliveira et al., 2010), intellectual capital (IC) marks as a sign of transition towards innovation, competitive advantage and sustainable development (SD) (Carrillo et al., 2009). According to Latif et al. (2020), stakeholders heavily pressure firms to minimise environmental issues arising from production activities (Singh et al., 2021). While firms worldwide have adapted rapidly to the dynamic changes in the competitive business environment to sustain their profits and gain competitive advantages, implementing IC to address environmental impacts is also essential (Singh et al., 2020). In order to address stakeholders' and environmental protection agencies' concerns and engage in green entrepreneurial actions, organisations must rely on their IC, such as green entrepreneurial orientation (GEO) (Guo et al., 2020). Researchers have empirically established the connection between GEO and financial performance (Fatoki, 2019;Jiang et al., 2018). In this study, GEO is proposed as a type of intellectual capital contributing to the long-term performance of small and medium-sized enterprises (SMEs) in developing nations (such as Pakistan and Malaysia).
IC is an essential intangible resource for entrepreneurial success (Crupi et al., 2020;Bamel et al., 2020) that firms have to develop to effectively implement corporate strategy, acquire and maintain sustainable competitive advantage, and improve sustainable performance (Alvino et al., 2020). In line with this, recent calls have been made for GEO to emerge as IC, as GEO can be a feasible solution for SMEs to attain SD under growing environmental threats (Crupi et al., 2020). The term "GEO" is defined as the combination of organisational strategies that captures a firm's strategic orientation, managerial policies, and entrepreneurial behaviours towards achieving sustainable competitive advantage (Jiang et al., 2018;Melay et al., 2017). The manufacturing industry has recently observed a comparatively higher adoption of IC practices which help GEO preserve the environment, conserve nature, foster green innovations, and facilitate entrepreneurial initiatives. Greater IC demonstrates higher knowledge concealment and higher employee skills and training to ensure business success (Hormiga et al., 2011), aligning with the manufacturing sector's nature that requires knowledge linkages, managerial skills, and employee training (Carayannis et al., 2021). The notion of GEO acts as a bridge for sustainability-driven innovation for businesses and has been committed to an important role in providing opportunities for green innovation, retention of CSR policies and increased competitive advantage. However, GEO initiatives carried out by companies in terms of SD must be in line with the expectations of the 17 Sustainable Development Goals (SDGs), which encourage them to contribute to creating a competitive advantage aimed at preserving environmental sustainability and well-being collective. According to (Cammarano et al., 2022), achievement of the SDGs requires a collective effort and cooperation between actors. In doing so, GEO is particularly affected by such changes towards new and sustainable ways of doing business. Consequently, nexus of GEO with SDG-oriented practices creates different opportunities within the procurement and distribution processes, and also solves business and sustainability issues. Thus, the link of GEO with the SDG-oriented practices may allow it to emerge and suggest a new path for environmental sustainability.
In the present study, manufacturing firms are considered as high-growth enterprises (HGFs) that experience rapid growth and develop new ideas and production methods to nurture IC (Segarra and Teruel, 2014). HGFs are believed to undergo greater change in a short time due to their ability to use greater IC to make entrepreneurial initiatives successful . Thus, HGFs exhibit outstanding entrepreneurial success, enabling their IC to experience more rapid expansion (Davidsson and Henrekson, 2002). Recent studies have revealed that GEO as IC can foster high-growth manufacturing companies to reduce deforestation and environmental problems (ozone layer depletion, rapid climate change, degradation of biodiversity) to preserve the ecosystem and potentially achieve sustainable development goals (Dean and Mcmullen, 2007;Youssef et al., 2018). Moreover, greater usage of IC can promote more physical or non-physical changes in the firms such as innovation opportunities, innovation adoption, socioeconomic productivity, and self-reliance, especially in developing countries. In addition, the manufacturing industry may be more vulnerable to IC practices that are more salient for entrepreneurial initiatives to maintain competitive advantage. Resultantly, this study sought to explain the role of GEO as IC in sustainable performance via the moderation of environmental consciousness and technology dynamism in the Pakistani and Malaysian manufacturing SME context. Despite scholars' growing attention towards the GEO concept Gray et al., 2014) and its relationship with firm performance (Jiang et al., 2018), how GEO influences sustainable performance remains unclear. Several prior works proposed the effect of GEO in the form of green products and services and green innovation (Guo et al., 2020), while others have theorised the positive impact of GEO on environmental performance (Shafique et al., 2021). Conversely, some studies suggested that GEO does not significantly affect financial benefits and competitive advantage (Pratono et al., 2019) or low carbon-based innovations (Xianjiang, 2012). In IC literature, most of the research did not explore any moderator in the relationship between GEO and sustainable performance. The present study adds to the body of knowledge by using environmental consciousness and green technology dynamism (GTD) as moderators that strengthen the relationship between GEO and sustainable performance. Nevertheless, very little attention has been drawn to explore the moderating role of GTD and environmental consciousness as IC in fostering GEO-sustainable performance link.
This study attempted to fill these research gaps by addressing GEO as SMEs' IC and examining its effect on sustainable performance, considering the inconsistent and insufficient findings on the performance outcomes of GEO. The study's aims were threefold. First, this study investigated the role of IC as GEO in SMEs' sustainable performance in developing countries by drawing on the intellectual capital-based view (ICV). Second, the moderating role of GTD between GEO and sustainable performance was assessed. Third, the moderating role of environmental consciousness between GEO and sustainable performance was evaluated. Accordingly, the researchers aimed to address the following research questions: (1) Does GEO influence sustainable performance?
(2) Does GTD moderate the association between GEO and sustainable performance?
(3) Does environmental consciousness moderate the association between GEO and sustainable performance?
In order to test the hypotheses, a data survey was conducted in the manufacturing sectors of Pakistan and Malaysia. The non-probability convenience sampling technique was utilised to collect data from 296 respondents from 264 manufacturing SMEs in these countries. The manufacturing sector was chosen because manufacturing firms' management systems effectively deal with entrepreneurial and environmental goals. The manufacturing sector is undoubtedly considered an important sector for the natural environment (Rehman et al., 2016). Nevertheless, manufacturers in developing countries are still grappling with severe environmental challenges and are looking for green entrepreneurial initiatives that could significantly provide solutions to this anthropogenic effect. Hence, green entrepreneurship appears to be a resilient factor for the developing countries' manufacturing sector (Trapp and Kanbach, 2021), which adds value to green technological advancement in the production process. Hence, the current study focused on the Pakistani and Malaysian manufacturing sectors. Consequently, Pakistani and Malaysian manufacturers must rethink their existing business models and promote green entrepreneurial initiatives to conserve the natural environment. Manufacturers can adopt GEO as intangible assets, the foreseeable choice to gain sustainable development and achieve natural environment conservation. Based on the previously discussed literature gaps, the present study is significantly original in three distinct ways. First, the present study proposes a change of perspective on the intellectual capital subject through the application of GEO and identifies how GEO enables different green entrepreneurial initiatives. In this study, GEO is identified as critical IC in managing and corresponding to green entrepreneurial initiatives that can foster sustainable performance and create value for a firm (Jiang et al., 2018). Several previous studies (Jiang et al., 2018;Fatoki, 2019) have explored the nexus between GEO and firm performance yet have paid limited attention to the link between GEO and sustainable performance. To the best of the authors' knowledge, this study is the first to explore GEO as firms' intellectual capital in fostering sustainable performance. Second, the current study explores the moderating roles of GTD and environmental consciousness between GEO and sustainable performance. Hence, the study hypothesises that firms with a higher level of GTD and environmental consciousness can encourage IC practices which foster superior sustainable performance. Finally, the present study explores the under-investigated GEO context of manufacturing SMEs in developing countries (Pakistan and Malaysia), wherein an untapped GEO-sustainable performance research framework was empirically tested. The study also attempted to gain deep insights into the role of GEO as a valuable intangible asset in shaping superior sustainable performance. The remainder of this paper is organised as follows. Section 2 justifies the study's conceptual framework and hypothesis development. Section 3 discusses the research methodology and data collection procedure, while Section 4 presents the data analysis results. Finally, Section 5 concludes the paper with a discussion of the findings, implications, and suggestions for future research.

Literature review and hypotheses development 2.1 Intellectual capital-based view (ICV)
The present study applied the intellectual capital-based view (ICV), which many influential authors have used in different works (Edvinsson, 1997;Luthy, 1998;Sveiby, 1997). According to Reed et al. (2006), ICV and the knowledge-based view (KBV) are counterparts with different scholarly foci. The KBV emphasises the effectiveness of organisational knowledge and knowledge generation streams (information system, information technology) and their influence on firm performance (Leonard-Barton, 1992). On the other hand, the ICV emphasises specific aspects, such as intangible assets, which foster the achievement of competitive advantage (Muhamad et al., 2016;Bamel et al., 2020). In this study, GEO is modelled as firms' intangible asset linked to sustainable performance. Thus, GEO refers to a firm's crucial IC which protects the natural environment and promotes sustainable development for economic growth through social and environmental objectives (Caputo et al., 2016;Bamel et al., 2020). As an IC, GEO can foster the detection, training, and exploitation of entrepreneurial initiatives, which sets up a mechanism for entrepreneurial potential to create and achieve a competitive advantage (Dean and Mcmullen, 2007;Hockerts and W€ ustenhagen, 2010). According to Fichter and Tiemann (2018), traditional entrepreneurship theory implements an amnesty mechanism along with a string of relief measures to promote economic benefits and self-employment. Unfortunately, the growing concern of environmental issues has been overlooked. Consequently, the concept of GEO, which strengthens a firm's intellectual capital, is merely employed to resolve environmental issues but adversely impacts firms' sustainable performance (Shahzad et al., 2020). Additionally, Reed et al. (2006) argued that the resourcebased view (RBV) is inappropriate for clarifying GEO's relationship with a competitive advantage. Thus, considering the theoretical shortcomings of the RBV, the present study drew upon the ICV to test the impact of GEO on firms' sustainable performance.

Green entrepreneurial orientation (GEO) as intellectual capital
In the competitive and uncertain contemporary business environment, companies must effectively utilise available tangible and intangible resources (Barney, 2001). Effective GEO, as a subset of intangible assets (Ma cerinskien_ e and Aleknavi ci ut_ e, 2011; Rao, 2012), is a crucial attribute of successful HGFs. High productivity and the related rapid growth of a company can be generated through investing, developing, and effectively utilising intangible assets (Mayo, 2000). Researchers have paid significant attention to the green entrepreneurship concept as an intangible asset, making GEO a considerable and prominent scholarly debate topic in the IC literature (Ma cerinskien_ e and Aleknavi ci ut_ e, 2011; Dwianika and Gunawan, 2020; Popescu, 2020). In addition to theoretical perspectives, firms have become increasingly vibrant in engaging in green entrepreneurship practice ((Dean and Mcmullen, 2007;Hockerts and W€ ustenhagen, 2010;Kibler et al., 2015). Indeed, GEO is crucial not only for green entrepreneurial initiatives, sustainable development, and training investments (Carayannis et al., 2014) but also for the protection of intellectual property (Yusoff et al., 2019). Increasingly environmentally sensitive consumers are the driving force behind green entrepreneurship and demand environment-friendly products (Del Giudice et al., 2021a). Consequently, green entrepreneurship encourages IC practices that mitigate organisations' environmental issues. According to Schaltegger and Wagner (2011), GEO is a progressive societal reform that contributes to intellectual capital practices that earn long-term business growth and unlock doors that had constrained them (Carayannis et al., 2021;Fait et al., 2021). Thus, businesses are adopting IC practices to foster green entrepreneurship to stay afloat while heading towards an ecosystem crisis (Hall et al., 2010;Shet et al., 2021). Hence, GEO as IC and its relationship with firm performance has been examined in various literature (Jiang et al., 2018;Fatoki, 2019;Habib et al., 2020) under different environmental conditions. Nevertheless, few studies examined GEO as an IC to foster green innovation (Guo et al., 2020;Muangmee et al., 2021), whose combined effects determine the success of a firm's eco-innovation. The changing global environment emphasises firms' need to consider the nexus of GEO-sustainable performance for a wide range of societal reforms and long-term competitive advantage. In achieving the sustainable development agenda, whether GEO plays an influential intangible asset role in shaping manufacturing SMEs' sustainable performance, particularly in developing countries, has rarely been examined.
The GEO-performance relationship literature is summarised in Table 1. Most existing studies on the relationship between GEO and performance were undertaken in developed countries, such as the European Union (EU) member countries (Criado-Gomis et al., 2017Hern andez-Perlines and Rung-Hoch, 2017). Research in developing countries primarily focused on China (Jiang et al., 2018;Guo et al., 2020;Guo et al., 2018;Li, 2013;Xianjiang, 2012;Xiue and Qing, 2021), Bangladesh (Habib et al., 2020), Indonesia (Pratono et al., 2019), Thailand (Muangmee et al., 2021), South Africa (Fatoki, 2019), and Iran (Golsefid-Alavi et al., 2021). Other developing countries, including Pakistan and Malaysia, have been mainly ignored. Furthermore, existing GEO-related literature has been found primarily in the contexts of hospitality and tourism (Fatoki, 2019;Luu, 2021), educational institutions (Guo et al., 2020), and the service sector (Xianjiang, 2012 in shaping manufacturing firms' performance has rarely been investigated, particularly in developing countries such as Pakistan and Malaysia. Moreover, extant research has failed to highlight any moderator in the GEO-performance relationship, despite some inconsistent findings. Nonetheless, previous scholars have examined mediators between this link, including green supply chain management (Habib et al., 2020), inter-organisational learning (Pratono et al., 2019), green creative self-efficacy (Luu, 2021), and green innovation (Muangmee et al., 2021). Adding to the body of knowledge, the present study utilised environmental consciousness and GTD as moderators that strengthen the GEOperformance relationship, which has rarely been considered in the literature.  (Bagnoli and Megali, 2011;. This dimension can be measured by assessing the degree to which social needs are satisfied. Hence, GEO can play a strategic role for an organisation to achieve the mission for which it was established and satisfy the interests of local communities, individuals, or social groups (Caputo et al., 2016).

Hypothesis
Organisations use GEO as an intellectual capital input to support business activities or processes to produce or supply goods or services (Ebrahim and Kasturi Rangan, 2014). Based on the ICV, GEO contributes to social welfare from multiple perspectives. First, a supplier's unethical behaviour impacts the public's perception of a firm, eventually diminishing social performance (Hajmohammad and Vachon, 2016). Nevertheless, consistent knowledge sharing with business partners through GEO enables firms to monitor and mitigate potential unethical practices (Casali and Perano, 2021). Second, socially responsible practices are more likely to be costly in the short run, exerting a financial burden on firms. Third, firms face financial constraints when investing in the latest technologies to achieve innovation in response to rapid environmental changes (Schaltegger and Wagner, 2011). On the other hand, large investments in the latest technologies may not produce large-scale benefits due to uncertainty in external market dynamism. Proactive (green entrepreneurial) firms can prevent such negative consequences in advance and forge better connections with business partners. In this regard, green entrepreneurial firms that proactively and strategically plan for long-term sustainable changes can potentially overcome the challenges of costly social responsibility and technological innovation to achieve superior social performance. Therefore, the following hypothesis was proposed: H1a. GEO positively influences social performance.

Relationship between GEO and environmental performance.
As an intangible firm asset, GEO is strongly embedded in entrepreneurial initiatives. By offering greater value to an organisation and being difficult for competing firms to imitate, GEO provides a basis for sustainable competitive advantage, which is solely derived from a pool of entrepreneurial mindsets and not from a tangible resource that can be easily bought or copied (Wright et al., 1994). Increased dynamism in the industry requires a core strategic resource, which provides a competitive advantage. In this way, GEO acts as an intangible asset that enhances competitive advantage and environmental performance. Acquiring new entrepreneurial initiatives and innovative skills helps a company perform efficiently (Shen et al., 2020). Consequently, entrepreneurial initiatives lead towards organisational sustainability (Morrish et al., 2011). Organisations cannot neglect environmental issues and aspects in today's highly competitive business environment. As a firm's intangible asset, GEO reduces environmental degradation and increases economic value by encouraging firms to avoid market failure and enhance market efficiency. Based on the ICV, firms adopt GEO to explore sustainable business opportunities, new technologies, and production methods, thus ensuring their survival and avoiding market failure . For instance, a firm is likely to reduce its pollution levels through new manufacturing processes that minimise the hazardous and toxic materials used in its production if it has a strongly developed GEO (Kaur et al., 2019). Moreover, GEO mandates the conservation of resources to advance firm efficiency. In this manner, green technologies aid water, coal, and oil wastage reduction throughout the production process (Graham and Mcadam, 2016). Besides, GEO also helps a firm comply with stringent international environmental standards, generates value for the organisation, and meets consumers' high environmental demands (Pratono et al., 2019). Therefore, GEO enables organisations to effectively implement their green agenda while concurrently meeting occupational health and safety management standards (such as ISO14000) (Popa et al., 2021). Ultimately, GEO does not just provide firms with a new mechanism to attract customers but also places firms as leading entrepreneurs and technical experts in global sustainability solutions. Therefore, exploring the impact of GEO on firms' environmental performance is essential (Kaur et al., 2019). In this regard, Habib et al. (2020) found a positive relationship between GEO and organisations' financial performance. Similarly, Guo et al. (2020) revealed a positive link between GEO and green innovative performance. In the light of these arguments, the study hypothesised that: H1b. GEO positively influences environmental performance.
2.3.3 Relationship between GEO and financial performance. Intangible assets are recognised as critical factors in generating the sustainable competitive advantage necessary to achieve superior financial performance (Barney, 1991). Bontis (2001) argued that leveraging knowledge assets is the key to a firm's prosperity. This pivotal role of intellectual capital in value creation must be assessed by estimating the extent to which firms' conventional financial performance measures intrinsically capture the contribution of intellectual capital resources such as human resources, customer reputation and relationships, and innovative ideas. The present study explored this issue empirically by analysing the relationship between a relevant measure of IC, that is GEO, and commonly used measures of a company's financial performance, representing profitability and productivity. Drawing from the ICV, implementing IC in the form of GEO strengthens a firm's capability to leverage its resources and knowledge for new products and processes (Covin and Miller, 2014). New innovative technologies specifically guide the better utilisation of resources, reducing water and fossil fuel consumption. Moreover, the use of recyclable materials is encouraged in production and delivery processes. For instance, firms should prioritise materials that are easy to reuse, recycle, and recover in manufacturing activities. Firms implement GEO due to institutional and social norms, as eco-friendly products and processes comply with environmental regulations and avoid government penalties (Dean and Mcmullen, 2007). Considering the arguments above, GEO reshapes production efficiency, minimises wastage, and reduces costs by exploiting innovative ideas, which improves firms' financial performance. Based on this discussion, the following hypothesis was suggested: H1c. GEO positively influences financial performance.
2.3.4 The moderating effect of green technology dynamism (GTD). Environmental problems have triggered global economies to achieve sustainable development goals. Concurrently, globalisation has given rise to environmental problems that emanate adverse climate change (Awan, 2013). On the whole, environmental problems are difficult to tackle due to their complexity, which only becomes more complicated for manufacturing firms. Moreover, green practices have been evidently neglected in developing economies, such as Pakistan and Malaysia (Malik et al., 2017). Businesses need to capture dynamic factors such as GTD, which can play a significant role in environmental management and sustainable performance to secure the foremost benefits. The dominance of the dynamic green technology domain has grown significantly among manufacturing firms (De Lange, 2016). In a changing environment, GTD has emerged as a "sign of certainty" for green technologies. Firms assimilate new technologies quicker than their competitors if they undergo and align with rapid technological changes. Thus, GTD fosters technology and knowledge capabilities.
Drawing upon the ICV, the present study has provided a theoretical foundation to explore the moderating role of GTD in the relationship between GEO and sustainable performance. From the perspective of the ICV, increasing environmental uncertainty raises firms' need to manage their intangible assets for better technological advancement (Widyaningdyah, 2020). Firms have a greater acceptance of GEO in introducing eco-friendly technologies and gaining superior sustainable performance if they adapt to GTD. When triggered by an uncertain business environment, GEO acts as an intangible asset that enhances the tendency to be proactive. Since GEO is tagged as risk-taking, firms with GEO perform better in a fast-changing or uncertain environment, especially when they have high environmental dynamism. Moreover, investment decisions are significantly associated with environmental uncertainty, whereby firms adopting GEO are willing to make risky investments for sustainable performance. Additionally, GTD provides a stable business environment for continued investment in entrepreneurial projects. According to Truong and Nagy (2021), GTD has a significant moderating effect on the relationship between a firm's intellectual capital and new product development performance. Therefore, a strong GTD may help firms achieve greater sustainable performance when their GEO is high. Based on the above arguments, the following hypotheses were postulated: H2a. GTD strengthens the relationship between GEO and social performance.
H2b. GTD strengthens the relationship between GEO and environmental performance.
H2c. GTD strengthens the relationship between GEO and financial performance.
2.3.5 The moderating effect of environmental consciousness. Environmental consciousness is rooted in the argument that the natural environment faces diverse environmental issues due to human actions, particularly pertinent to the manufacturing sector (Yucedag et al., 2018). Anchored in the ICV as its theoretical foundation, the present study postulates the moderating effect of environmental consciousness on the relationship between GEO and sustainable performance. According to Yucedag et al. (2018), employees' consciousness about environmental issues would engage them in specific behaviours that could protect the environment, including green entrepreneurial initiatives. Employees who are passionate and aware about environmental issues (climate change, environmental degradation, resource depletion, global warming, pollution and noise, waste and hazard reduction) tend to undertake necessary actions related to environmental conservation (Cheema et al., 2020;Testa et al., 2016). Thus, employees' consciousness about environmental issues has become essential to stimulating employee engagement in GEO. In turn, employees' environmental consciousness would increase if they adopt green entrepreneurial values in their behaviours. The ICV further suggests that employees engaging in green entrepreneurial activities would support IC practices, such as new environmental initiatives and social responsibility activities, to achieve firm performance (Shafique et al., 2021). The employees may also promote green behaviours and GEO practices among one another. Moreover, employees' higher environmental consciousness level is likely to enhance the effect of their GEO engagement on sustainable performance since manufacturing sector employees' selfperceptions are deeply related to the environment. Based on the above arguments, the study hypothesised that: H3a. Environmental consciousness strengthens the relationship between GEO and social performance.
H3b. Environmental consciousness strengthens the relationship between GEO and environmental performance.
H3c. Environmental consciousness strengthens the relationship between GEO and financial performance.

Research framework
The study's primary objective was to investigate the positive effect of GEO on sustainable performance among Pakistani and Malaysian SMEs. The study further aimed to ascertain the moderating role of GTD and environmental consciousness in the relationship between GEO and sustainable performance. Sustainable performance was measured as social, environmental, and financial performance. Figure 1 presents the framework of this research.

Methodology and sampling 3.1 Pakistani and Malaysian manufacturing SMEs
The manufacturing sector has the potential to lead global economies towards green transformation, given their substantial harmful contribution to environmental pollution and waste. In developed economies (such as EU nations), manufacturing firms contribute about 60%-70% of gross domestic product (GDP) growth and manage their industrial environmental pollution (air pollution, waste management, energy and resource consumption, and hazardous materials) to enhance sustainable performance (Hall and Oriani, 2006). Nevertheless, in developing economies (such as Asian countries), manufacturing firms are the major polluters of the atmosphere and create sustainability problems such as climate change, chemical waste, hazardous material, natural resources depletion, and noise and air pollution (de Sousa Jabbour et al., 2020). According to Khan and Khalique (2014), manufacturing firms' waste and pollution can threaten living species' survival on Earth. In Pakistan and Malaysia, more than 6% of carbon dioxide (CO 2 ) emissions have been documented explicitly on an annual basis. The disposal of used products, waste prevention, and emissions control are less-structured and lack effective mechanisms are practised in these developing economies. Cleaner productions and closed-loop mechanisms are acknowledged as under-developed and less-proactive in these countries, notably Malaysia and Pakistan. In previous studies, the paucity of green entrepreneurial practices has been noted to badly affect sustainability policies, worsening environmental degradation (Arend, 2014;Soomro et al., 2020) and creating numerous environmental problems such as illegal dumping, growing landfills, and human and environmental health issues. Based on the explanations mentioned above, the present study chose GEO as an antecedent and sustainable performance as an outcome for this study. Besides, the current study uses GTD and environmental consciousness as moderators, which strengthens the link between GEO and sustainable performances.

Sampling
The present study selected Malaysian and Pakistani SMEs as the study population to assess green entrepreneurship and sustainable performance in developing economies. The sample of SMEs in Malaysia was chosen from two major states, namely Selangor and Kuala Lumpur, respectively. Likewise, the sample of Pakistani SMEs was from two major provinces with the highest contribution to Pakistan's national GDP, namely Punjab and Sindh. Punjab is considered the largest province in terms of GDP contribution with approximately 173 billion rupees in 2019 and is rapidly increasing, while Sindh's GDP contribution stood at 83 billion rupees. The G*Power 3.1.9.2 software was utilised to determine the minimum sample size for this study. The software is considered reliable and recommended for sample size calculation (Cohen, 1992). Based on the parameters proposed by Cohen (1992), with an effect size of 0.17, error probability of 0.05, and power of 0.90, the software reported that this study required a minimum of 120 respondents.

Three-wave research design
The current study applied a three-wave research design, which permitted time-based segregations of each variable. In particular, the independent variable (GEO) was measured at Time 1, the moderator variables (GTD and environmental consciousness) were measured at Time 2, and the dependent variable (sustainable performance) was measured at Time 3. The time lag between every measurement was at least three to four weeks. This design mitigated the potential issues from exclusively using self-reported or single-source data at one point in time. Finance managers, chief executive officers (CEOs), and presidents of the SMEs were targeted as proxies of the sample firms. A structured closed-ended questionnaire was sent to these target respondents at the aforementioned three separate time points to obtain the required data. A total of 620 questionnaires were distributed to 122 manufacturing SMEs in Pakistan using the non-probability convenience sampling technique. Finally, 160 questionnaires were completed and returned, yielding a 25.80% response rate for the respondents at Time 1, Time 2, and Time 3. Similarly, 700 questionnaires were distributed to 142 manufacturing SMEs in Malaysia. After several follow-ups by email and phone, 136 completed questionnaires were collected, yielding a 9.42% response rate for the respondents at Time 1, Time 2, and Time 3.

Common method bias (CMB)
Common method bias (CMB) is a potential concern when data is collected on endogenous and exogenous constructs across different time periods through the questionnaire survey method (Kraus et al., 2020). CMB can diminish a study's results (Podsakoff et al., 2003;Spector, 2006) and over-report the existing association between the study's measured variables (Conway and Lance, 2010). Hence, the current study applied Harman's single factor test for CMB, where the highest variance explained by a single factor should be less than 50%. Table 2 shows that the highest variance explained was 21.047%, indicating no CMB in the present study.

Measures
The present study adapted all the measurement items from previous research, rated on a seven-point Likert scale ranging from 1 (strongly disagree) to 7 (strongly agree). First, the scale for GEO was adapted from Jiang et al. (2018). The GEO measures expressed it as an intangible asset that can exploit the firm's overall intangible assets to respond to the rapidly changing environment and address environmental concerns. Second, the scale for GTD was adapted from Sheng et al. (2011). The items in the scale referred to the uncertainty of the green technological perspective and external environmental changes. Third, the items for environmental consciousness were measured using the scale by Huang et al. (2014). Environmental consciousness is referred to as an employee's consciousness about environmental issues, which is an essential characteristic that encourages them to engage in GEO. Next, social performance items were adapted from Zailani et al. (2015). Social performance was operationalised as an organisation's effective mechanism that converts its mission into actions in line with accepted social mores. Subsequently, environmental performance items were adapted from Zailani et al. (2015). Environmental performance was defined as the stakeholders' expectations and firm principles that an organisation achieves in fulfilling environmental-related requirements. Finally, financial performance items were also adapted from Zailani et al. (2015). Financial performance was operationalised as the subjective measures that a firm utilises to achieve its economic and financial objectives. The present study also incorporated four control variables (firm age, industry type, firm size, and ownership structure) that are commonly used to assess firm performance (Li et al., 2018) (see Table 3).

Reliability and validity
An exploratory factor analysis (EFA) was applied using the varimax rotation and an eigenvalue cut-off above 1.0 to evaluate whether the item loadings for each construct were valid in Pakistan and Malaysia (Hair et al., 2010). The factor analysis comprised six factors with eigenvalues above or close to 1.0 for all items, indicating the unidimensional characteristics of the constructs. Cronbach's alpha was subsequently used to assess the reliability of the constructs. As shown in Table 4, the Cronbach's alpha values for all the six constructs were greater than 0.70 in Pakistan and Malaysia, fulfilling the acceptance criterion for reliability (Carmines and Zeller, 1979). Furthermore, the computations of composite reliability (CR) confirmed the reliability of the scales with values greater than 0.80 in Pakistan and Malaysia. Next, convergent and discriminant validity were evaluated using confirmatory factor analysis (CFA). As shown in Table 4, the average variance extracted (AVE) value of each construct was greater than the threshold of 0.50, confirming convergent validity. Table 4 also shows that the square root of the AVE for each construct was higher than its correlations with other constructs (Fornell and Larcker, 1981). Therefore, discriminant validity was also verified for the data from Pakistan and Malaysia. all latent factors) are presented on the diagonal of the correlation matrix in Table 5. For all factors, this value exceeds any correlation with another factor, indicating satisfactory discriminant validity.

Hierarchical regression analysis
The results of the hierarchical regression analysis for Pakistan are presented in Table 6. In Pakistan, H1a was rejected as GEO was found to negatively and insignificantly influence social performance (β 5 À0.085, n.s., Model 2). Nevertheless, H1b and H1c were supported as GEO positively influenced environmental performance (β 5 0.299. p < 0.001, Model 5) and financial performance (β 5 0.391, p < 0.001, Model 8). Moreover, GTD was found to positively moderate the relationship between GEO and environmental performance among Pakistani SMEs. The effect of the interaction coefficient of GEO and GTD on social performance was insignificant and negative (β 5 À0.089, n.s., Model 3). Hence, H2a was rejected. Table 6 illustrates that the interaction coefficient of GEO and GTD was significant and negative for environmental performance (β 5 À0.139, p < 0.05, Model 6), supporting H2b. In addition, H2c was also rejected as GTD failed to moderate the relationship between GEO and financial performance, with an insignificant and negative interaction coefficient (β 5 À0.040, n.s., Model 9). Next, H3a failed to be supported as the interaction coefficient of GEO and environmental consciousness had an insignificant and negative effect on social performance (β 5 À0.095, n.s., Model 3). Similarly, H3b was also rejected as Table 6 illustrates that the interaction coefficient of GEO and environmental consciousness was insignificant and negative for environmental performance (β 5 À0.034, n.s., Model 9). Nonetheless, the interaction coefficient of GEO and environmental consciousness was significant and negative (β 5 À0.132, p < 0.05, Model 9), proving the moderating effect of environmental consciousness between GEO and financial performance. Hence, H3c was accepted.
As shown in Table 7, GEO was found to positively influence social performance (β 5 0.204, p < 0.01, Model 2), environmental performance (β 5 0.280. p < 0.001, Model 5), and financial performance (β 5 0.159, p < 0.01, Model 8) in Malaysia. Therefore, H1a, H1b, and H1c were all supported. Nevertheless, GTD failed to moderate the effect of GEO on social      performance, as the interaction coefficient was insignificant and negative (β 5 À0.062, n.s., Model 3). Thus, H2a was rejected. On the other hand, H2b was accepted as the interaction coefficient of GEO and GTD was significant and negative for environmental performance (β 5 À0.135, p < 0.05, Model 6). Table 7 illustrates that the interaction coefficient of GEO and GTD had an insignificant and negative effect on financial performance (β 5 À0.011, n.s., Model 9), which rejected H2c. Likewise, the moderating effect of environmental consciousness between GEO and social performance was insignificant and negative (β 5 À0.021, n.s., Model 3). Thus, H3a was rejected. In contrast, H3b was supported as environmental consciousness was found to significantly and positively moderate the relationship between GEO and environmental performance (β 5 0.124, p < 0.05, Model 6). Similarly, the interaction coefficient of GEO and environmental consciousness for financial performance was significant and positive (β 5 0.132, p < 0.05, Model 9), thereby confirming H3c. For Tables 6 and 7, hierarchical regression analysis was used to analyze whether GTD and environmental consciousness moderate the relationship between GEO and sustainable performance, following Preacher and Hayes (2008) approach. To calibrate for bias, 5000 bootstrap samples and a 95% confidence interval (CI) were applied, allowing for the calculation of the indirect effect of each variable. If the confidence interval for the indirect effect of a given variable did not include 0, this was taken as an indication that the indirect effect in question was significant at p 5 0.05 (Baron and Kenny, 1986;Hayes, 2013).

Discussion
The study aimed to investigate the influence of GEO, as IC, on manufacturing SMEs' sustainable performance with the moderating effects of environmental consciousness and GTD. The present study addressed the research questions by drawing on the ICV and using data from Malaysian and Pakistani SMEs. The findings revealed that GEO has a direct and significant relationship with environmental and financial performance in Pakistan, consistent with previous literature findings (Habib et al., 2020;Jiang et al., 2018). Surprisingly, GEO does not affect social performance in Pakistan, contradicting past empirical findings (Habib et al., 2020). The findings revealed that GEO in Malaysia has a direct and significant impact on all three facets of sustainable performance (social, environmental, and financial), aligning with earlier scholars' findings (Fatoki, 2019;Habib et al., 2020;Jiang et al., 2018). The present study's findings have proven that IC, such as GEO, has different results across countries, differing from the work of Lomberg et al. (2017). Notably, the results of the direct relationships suggest that Malaysia is a developed economy with more advanced and resourceful collaborations for business opportunities than Pakistan. In contrast, Pakistan lacks an entrepreneurial process. Hence, the government and external environment needs different capital and development support to acquire a sustainable business model for social performance. The results of the direct relationships further show that GEO plays a vital role in the development of entrepreneurial actions, as it is categorised by green innovativeness, pro-activeness, and openness to risk. First, as per the ICV perspective, GEO leverages and modifies existing IC (launching new innovative products and processes). For example, the development of eco-design practices leads firms towards reducing toxic and hazardous material and minimising environmental impacts (health and safety) for the social welfare of their employees and society. Second, a strong GEO permits firms to discover, create, and exploit new business opportunities to achieve an eco-friendly product and process that satisfies market demand from customers. Indeed, strong IC development, such as GEO, enables firms to recognise business opportunities for expanding their market shares. Third, GEO reflects the characteristics of risk-taking. As far as the ICV is concerned, internal structure transformation and business model expansion are risk-taking decisions. When a new task is applied in the traditional business model, a firm inherently faces structural risk, which is higher for firms relying on IC. Hence, protecting the firm's intellectual capital to compensate for inherent risk is essential. Overall, the researchers assert that GEO acts as a reliable predictor of environmental performance (Menguc and Ozanne, 2005), financial performance (Dean and Mcmullen, 2007), and social performance (Kraus et al., 2012). The second research question inquired whether GTD moderates the relationship between GEO and sustainable performance. The findings indicate that GTD has a significant moderating role between GEO and environmental performance in Pakistan and Malaysia, supporting previous findings (Jiang et al., 2018). Nevertheless, GTD failed to moderate the relationship between GEO and the remaining two sustainable performance aspects (social and financial) in Pakistan and Malaysia. These results diverge from the extant literature (Jiang et al., 2018), possibly due to the complexity of environmental issues in developing countries. Thus, the study provides empirical evidence that GTD is a vital contingent factor in the relationship between GEO and environmental performance, revealing three crucial implications. First, greater adoption of GTD may produce highly novel knowledge and technologies. Entrepreneurial projects are likely the duration of long-term business models. The adoption of GTD may create environmental ethics of responsibility to initiate green projects aimed at increasing marginal and incremental rates of return (Chan et al., 2016). A firm's knowledge dynamism becomes more stable and diversified than the existing business environment with the higher adoption of GTD. Moreover, the absorption cost controls the firm, whereas novel knowledge and technologies create useful innovations. Second, higher consumer purchasing power would increase customers' preference for eco-friendly products, influencing social recognition, functional values, and advanced technology (Biswas and Roy, 2015). Therefore, the effective implementation of GEO would augment consumers' tendency for better social responsibility and sustainable consumer behaviour, which benefits better sustainable performance. Third, consumers are likely to pay less attention to entrepreneurial actions. Hence, increasing awareness on the welfare of eco-friendly products and services would fill the gap in consumers' environmental awareness and direct their behaviour towards green products and services consumption. Therefore, consumers will be more likely to adopt green products and services if environmental awareness is increased at the general level of the public.
Lastly, the third research question pertained to the moderating role of environmental consciousness in the relationship between GEO and sustainable performance. The study analysis reported that environmental consciousness is a significant moderator between GEO and financial performance in Pakistan, as evidenced in the literature (Magaji et al., 2017;Huang et al., 2014;Jang et al., 2015;Mart ınez Garc ıa de Leaniz et al., 2018). Notably, environmental consciousness has an insignificant moderating effect between GEO and social and environmental performance in Pakistan, contrary to the work of Wong et al. (2012). This study further discovered that environmental consciousness in Malaysia has a significant moderating effect between GEO and environmental and financial performance, as per previous empirical findings (Huang et al., 2014;Jang et al., 2015). Nevertheless, environmental consciousness does not moderate between GEO and social performance, which contrasts earlier research by Mart ınez Garc ıa de Leaniz et al. (2018). In addition, the findings demonstrate that greater environmental consciousness strengthens the effect on several sustainable performance elements, which is consistent with the past literature (Huang et al., 2014;Jang et al., 2015). The findings particularly imply that consumers' environmental consciousness creates greater emotional attachments to green products. Consequently, consumer loyalty for green products and services increased. Notably, the results reveal that Malaysian SMEs are more environmentally conscious than Pakistan SMEs, resulting in the former's better sustainable performance. For example, Starbucks began selling fresh juice in their stores after partnering with Evolution Fresh Juice. Consequently, Starbucks was able to address its health-conscious consumers' needs, thereby improving its sales turnover. In addition, Good Guide's website and mobile apps provide information related to the health, environmental, and social benefits of products and companies to facilitate consumers' choice of green and socially responsible products.

Comparative analysis with previous studies
Most of the extant GEO literature has focused on organisations in developed and developing nations, such as the EU member countries, China, Bangladesh, South Africa, Indonesia, Asia-Pacific, Thailand, and Iran. Scholars from these regions have found that the effective management of GEO has a strong link with firms' entrepreneurial success (Criado-Gomis et al., 2017;Hern andez-Perlines and Rung-Hoch, 2017;Jiang et al., 2018;Guo et al., 2020;Guo et al., 2018;Li, 2013;Xiue and Qing, 2021). A burgeoning track of research has started to explore the GEO concept in SMEs operating in developing and under-developed economies, such as Malaysia and Pakistan, due to the overwhelming acknowledgement of the positive role GEO plays in the developing world. According to Bontis et al. (2000), intellectual capital significantly contributes to Malaysian SMEs' performance. Other researchers have corroborated this finding (Daud and Yusuf, 2008;Ngah et al., 2009). Similarly, according to Khalique et al. (2015), intellectual capital plays a significant role in Pakistani SMEs. Nevertheless, a lack of empirical research was observed within the GEO context, particularly with regard to an in-depth, focused examination of IC practices in Pakistani and Malaysian SMEs. The comparative analysis of Malaysian and Pakistani SMEs in the GEO context is noteworthy for many reasons. First, Pakistan and Malaysia are developing economies experiencing a high level of turbulence, complexity from environmental dynamism, and a lack of entrepreneurial activity mechanisms (Khan and Khalique, 2014). Consequently, when comparing Malaysian and Pakistani SMEs, both market structures appear to have unique characteristics (lack of formal institutional support, co-existing non-state-owned and state-owned enterprises, lack of market-support institution, less-developed mechanism for surrounding services, limited mechanism of entrepreneurial action) (Khalique, 2011). Second, developing economies' specific characteristics have pushed their manufacturing sector into a complicated and unpredictable environment (Acs et al., 2008;Del Giudice et al., 2021b). Hence, manufacturing firms, especially pollution-intensive and less entrepreneurial firms, aim for rapid advancement in developing economies. Third, Pakistani and Malaysian SMEs have generated insignificant challenges to economic growth in dealing with environmental issues and green entrepreneurship practices in their manufacturing process. Hence, whether GEO plays an influential intellectual capital role in shaping Pakistani and Malaysian manufacturing firms' sustainable performance has rarely been investigated. The concept of GEO is still in its embryonic stages in these developing nations despite the significant contributions researchers have made in other fields. Therefore, the present study is the first to study the concept of GEO as intellectual capital in Pakistani and Malaysian SMEs to determine whether extant measures and constructs are generalisable across multiple developing nations.

Implications for theory
The present study has contributed to the literature in several ways. First, the study applies the ICV to green entrepreneurship by addressing a firm's strategic and entrepreneurial orientation (GEO) as a vital IC. By doing so, this research establishes that GEO and intellectual capital are subtly interconnected through three different characteristics: (1) a desire to explore green innovation; (2) pro-activeness to grab business opportunities; and (3) an open attitude towards risk-taking and transforming the social economy. Second, this study affirms the significance of intellectual capital by establishing that GEO positively influences sustainable performance, an ambiguous area in the intellectual capital literature (Carayannis et al., 2014). Third, previous research has primarily relied on the institutional theory merits, specifically institutional factors and logic (Schaltegger and Wagner, 2011). This research adopted and extended the ICV to demonstrate the multiple intellectual capital components comprising firms' entrepreneurial behaviour, which ultimately lead towards sustainable performance. Fourth, most GEO research has been undertaken in developing economies (China, Iran, Bangladesh, and South Africa). Nevertheless, GEO adoption is more sensitive and critical in developing countries (Pakistan and Malaysia).

Implications for practice
The present study has also addressed several practical implications. First, firms are recommended to recognise GEO as an intellectual capital that allows the exploitation of intangible assets for future business opportunities in the marketplace. Intellectual capital like GEO encourages entrepreneurial actions (e.g. introducing new technology) and enhances selfawareness. Second, managers should address and adapt to technological changes to stabilise their business environment, which in turn engenders economic benefits. Third, managers should encourage employees to discover business opportunities, engage in entrepreneurial activities, and avoid failures between cross-functional contexts in the firm. Next, intellectual capital highlights the growing need to address innovation and entrepreneurship. A firm nurtures sustainable entrepreneurship to secure improved performance by encouraging managerial discussions of intellectual capital concerns (Nave and Franco, 2019;Schaltegger et al., 2016). Fourth, the implementation of GEO aligned with SDG-oriented practices could help managers to take into account the implications of green practices in line with the UN 2030 agenda, when managers decide to redesign and reorganise their operational practices. In this sense, the choice of SDG-oriented practices will be affected not only by criteria related to the business, but also by those related to sustainability (Cammarano et al., 2022).

Limitations and future research
One of the study's limitations is that GEO was measured with a single informant from each firm who provided self-reported data, which has been criticised for potential bias. Although several remedial measures were undertaken in this study and CMB was not present, it might lead to bias in future studies. Considering the possibility of CMB stemming from the singlesource used in this study, future research is recommended to evaluate GEO by sampling multiple levels of employees and managers. Next, the present study only investigated the moderating effects of GTD and environmental consciousness on sustainable performance. Future studies must expand this body of knowledge by considering the moderating role of various factors, such as system thinking, open and experimental environments, and management commitment. Finally, this research was limited by its specific sample of SMEs and only two developing countries' contexts. The experience and implementation of GEO could be compared across developed and developing economies in upcoming studies. Therefore, future research should attempt to reveal in-depth generalisable conclusions in diverse settings.

Conclusion
The growing IC trend has given a tremendous boost to SMEs' sustainable development through strategic efforts such as GEO. The adoption of GEO may illuminate critical strategies for firms to achieve a competitive advantage and enhance sustainable performance. Based on the ICV, this research revealed that IC (GEO) positively influences firms' sustainable performance in social, environmental, and financial aspects. Thus, this study has recognised the role of GEO as IC for exploiting business opportunities, encouraging innovativeness, and taking risks for transformation to achieve social, environmental, and economic benefits. Moreover, the moderating roles of GTD and environmental consciousness in these relationships were established based on the premise that GTD and environmental consciousness strengthen and promote knowledge management capabilities that translate GEO into sustainable performance.
