The influence of corporate social responsibility activities on customer value co-creation: the mediating role of relationship marketing orientation La influencia de las actividades de responsabilidad social corporativa en la co-creaci on de valor para el cliente: El papelmediador de la orientaci on delmarketing relacional

Purpose – This paper aims to investigate the impact of external stakeholders-related corporate social responsibility (CSR) activities (local community and suppliers) on customer value co-creation behavior. This study also aims to examine the mediating role of relationship marketing orientation (RMO) on the relationship of CSR activities and customer value co-creation behavior. Design/methodology/approach – The main problem of dichotomy between customers and the management was existing in banking sector so that’s why through purposive sampling, banking customers were selected for data collection through a self-administered questionnaire. Structural equation modeling was used to test the proposed hypotheses. Findings – The present study found that both local community-related and supplier-related CSR activities have a positive impact on customer value co-creation behavior. Relationship marketing orientation mediates between the link of CSR activities and customer value co-creation behavior. The strength of RMO in CSR supplier and customer value co-creation behavior is found to be more dominant. Research limitations/implications – This study is restricted to one country under-investigation; therefore, it can be replicated with a larger andmore geographically diverse sample. © Muhammad Mubushar, Norizan Bt Jaafar and Rossazana Ab Rahim.

Introduction
In rapidly changing environment, customers have transformed their traditional role and looking for customized products/services with the ease of information, awareness and technology (Wu et al., 2016;Kumar et al., 2018). In this scenario, relationship building with stakeholders such as customers remains the core activity of any company (Royle and Laing, 2014;Kumar et al., 2018), and corporations are under high stress to discover new methods of participation in defensible development and meeting ethical expectation.
To meet this challenge, one platform is corporate social responsibility (CSR) on which a corporation can reflect stakeholders' orientation to address special issues (Planken et al., 2013;Rosa et al., 2017). CSR is: SJME 24,3 [. . .] the commitment of business to act ethically and contribute to the development of the economy while improving the quality of life of the employees, their families, customer, and local community as well as society at large (Watts, 2000).
Due to its significant impact on firms' efficiency and performance (Benlemlih and Bitar, 2018), CSR has become an international agenda for corporations as well as public and private institutions (Ruiz-Alba et al., 2014;Terrero-De La Rosa et al., 2017). Therefore, 90% of the top 250 largest companies in the world are investing in socially responsible activities and published their CSR reports (KPMG, 2015). European cluster (Eastern Europe, Continental Europe, British Isles, Northern Europe and Mediterranean Europe) has also developed 499 CSR initiatives with the help of the best 178 leading member corporations of European business networks (Maon et al., 2017). Even though it is largely acknowledged that CSR is a product of Western countries, but it has gained a significant amount of attention in the Asian region, both in the corporation and academia (Fifka, 2012). Reporting of CSR investment has increased up to 50% in Asia especially in Indonesia and Malaysia (KPMG, 2016;Arena et al., 2018).
After introducing mandatory CSR investment and discloser by the Security Exchange of Pakistan in 2013, most Pakistani industries are catching up with their counterparts in developed countries in terms of their CSR initiatives (Chaudary et al., 2016;Syed and Butt, 2017). The banking industry of Pakistan is deeply involved in CSR activities by improving electronic banking, investing in various social NGOs and contributing to the betterment of human beings (Khan et al., 2014). Bank Al Habib donated Rs. 159.8m to underprivileged people for health, education, social and welfare development. MCB bank is one of the market leaders in the entire banking sector to serve the internal and external stakeholders including the community (Arifeen, 2018). Currently, most Pakistani banks have included CSR in their mainstream strategies. Despite their significant effort, CSR is unnoticed by customers due to the lack of engagement between stakeholders, and this problem has widened the gap between the customers and the management of the banks (Yunis et al., 2017;Khan et al., 2014). This is one of the main reasons that CSR in Pakistan is underexplored (Bagh et al., 2017;Ashraf et al., 2017). To address this issue, research scholars and practitioners have conducted in-depth studies on CSR activities to learn the changing role of customers in the complex environment of banking (Oberseder et al., 2014;Li et al., 2017) but could not create consensus. Similarly, some recent developments have created crisis in banking industry of Pakistan. For example, Federal Investigative Agency (FIA) issued a list of 400 most powerful personalities and bankers who were involved to move 200 billion rupees from factious bank accounts and products. Along with this, a huge amount was stolen from the customers' accounts through phone calls and Web links by fraudsters (Pakistan Today, 2018: ProPakistani, 2019. The regulatory bank has charged penalties worth Rs. 773m on nine major banks in August 2019 for breaking the rules and regulations. All these fresh incidents have badly shaken the confidence of customers, and they are less convinced to use the banking channels. They leave the banks and move toward cash-based transactions which explains Pakistan's 36% undocumented economy (Mangi, 2012). Thus, the current study attempts to explore the relationship between CSR activities and customer value cocreation in banking industry of Pakistan to understand the changing behavior of customers. The outcomes of study would help to minimize the gap between the customers and the management.
Furthermore, consumer's perspective is less explored (Lee et al., 2011;Bolton and Mattila, 2015) and prior research related to CSR focuses mainly on the relationships of CSR and behavioral consequences of customers such as the impact of CSR on customer loyalty (Pérez and Rodríguez del Bosque, 2017;Fatma et al., 2018;Ajina et al., 2019;Mohammed and Al-Role of relationship marketing orientation Swidi, 2019). Many scholars have explored the role of CSR in purchase intentions, the impact of CSR and customer preferences and customers' reactions Bae et al., 2019;Tingchi Liu et al., 2014;Anadol et al., 2015). Yet, the concept of CSR and customer value co-creation behavior are still underexplored (Dechiara, 2012;Ahen and Zettinig, 2015;Luu, 2019). CSR must be conducted based on other customers' behavioral aspects because customers are changing their traditional and passive role as a merely recipient of services/ products to being an active participant in value co-creation: customer participation behavior and customer citizenship behavior (Vargo and Lusch, 2014;Yi and Gong, 2013;McColl-Kennedy et al., 2012). Research have been conducted to study the importance of customer involvement in social responsibility, and it was found that value co-creation behavior is essential to meet the changing dimensions of a marketplace in the contemporary world (Ida, 2017;Wagner, 2017). However, there are extremely limited research on the effects of CSR dimensions on customer value co-creation. Moreover, the researchers seek to find a mechanism that links relationship marketing orientation (RMO) with CSR activities and customer value co-creation behavior. For effective value co-creation, interface is very important between customers and service providers (Vargo and Lusch, 2008). RMO relationship activities for the interest of customers and cocreates values through reciprocal contribution (Gruen et al., 2000). RMO is also a further investment of companies for the development of a long-term relationship with stakeholders (Knox and Gruar, 2007). In this way, RMO can serve as a mediator between CSR actions and customer value co-creation behavior.
This study has three contributions: the first and foremost is academic contribution. Based on stakeholder theory, this study extends the literature of CSR to customer value cocreation behavior. This adds on to the existing body of literature that only links CSR with customers passive outcomes such as loyalty, purchase intentions and repurchase intentions Bae et al., 2019). The current study will break the concept of CSR into dimensions, namely, CSR local community and CSR suppliers, and highlight their roles in customer value co-creation behavior. Second, this study emphasizes on the indirect role of RMO between CSR activities and customer value co-creation behavior to build the qualityoriented relationship between customers and service providers.
The final contribution is that this study applied stakeholder theory highlight on noneconomic value of stakeholders, while most studies on CSR use stakeholder theory to maximize the value of shareholders (Harrison and Wicks, 2013). This is the first study which uses this theory and explores the relationship between CSR dimensions and customer value co-creation behavior.
2. Literature review 2.1 Local community-related corporate social responsibility activities and customer value co-creation behavior Companies have plentiful resources to bring prosperity for the community; therefore, CSR is considered to be a very important mechanism to strengthen the link between corporations and the local community for the economic stability of the society in the longer run (NEAC, 2010). CSR campaigns enable communities to be more than just a market in the eyes of business; therefore, corporations ought to understand which CSR activities are closely aligned with the community when planning CSR strategies. Local community-related CSR is a set of philanthropic activities which brings improvements in the community in terms of employment, health, education, water supply, sanitation, etc. (Maloni and Brown, 2006;Aguilera et al., 2007;Ismail et al., 2015). Customers are likely to observe the tangible features of firms that encourage their participation. Thus, they tend to respond positively to community-orientated projects that are closely linked with customers (Marquina Feldman and Vasquez-Parraga, 2013).
Understanding the customers' response to stakeholders-oriented CSR activities, many scholars proposed that well-executed community-related CSR programs may enhance customer based behavioral outcomes (Halkias et al., 2013;Tingchi Liu et al., 2014;Pérez and Rodriguez del Bosque, 2015). If a vigorous relationship has been found between communityoriented CSR activities and its positive consequences, then studies must be able to check the relationship between local community CSR and more specific aspects of customers such as customer value co-creation behavior because following service-dominant logic, customers are always operant resources for value co-creation (Vargo and Lusch, 2004;Vargo and Lusch, 2008). Customers have changed their traditional passive role in services as they are not only demanding services but also tend to participate actively by a unique alliance between companies and customers (Zhang et al., 2015;Rialti et al., 2018). A number of scholars proposed that philanthropic activities create the added value for the community as well as for the company because its altruistic values give a sense of connection and identification to the customers (Sen et al., 2006;Pérez and Rodriguez Del Bosque, 2015). When they perceive the value to be close to their own identities, they are more likely to share their values. However, these are just assumption as the relationship between CSR activities and customer value co-creation value is limitedly explored (Laczniak and Murphy, 2006;Ahen and Zettinig, 2015;Luu, 2019).
Thus, the current study seeks to test the relationship between local community-oriented CSR activities and customer value co-creation behavior. This behavior is the combination of dual factors: customer participation behavior such as information seeking, information sharing, responsible behavior and personal interaction and customer citizenship behavior which include giving feedback, showing advocacy, helping and being tolerant (Yi and Gong, 2013). With the help of community members' understanding of the customers' participation, prospects can be improved (Kamboj and Rahman, 2017;Sanclemente-Téllez, 2017;Bharti et al., 2014). Similarly, customers have a high tendency to demonstrate extra-role behavior that is the customer citizenship behavior if they perceive that the company is more ethical and interdependent on society's welfare (Karaosmanoglu et al., 2016). This leads to the following hypothesis: H1. Local community-related CSR activities positively affect (a) customer participation behavior and (b) customer citizenship behavior.

Supplier-related corporate social responsibility activities and customer value co-creation behavior
To become socially responsible, firstly a company needs to be a good partner to its good business partner. A firm can force its business suppliers to improve the prospects of products/services by educating about quality goals as per adopted standards and mutually agreeing on quality control procedures (Longo et al., 2005). Focusing on the labor standard of business partners and other business suppliers in compliance with legalities as well as executing procedures for them is seen as part of CSR practices within the corporations (Graafland and van de Van, 2006;Skudiene and Auruskeviciene, 2012). It means all the CSR activities consisting of fair dealings with suppliers and other business partners fall under the category of supplier-related CSR. CSR has been gaining the utmost importance in the domain of supply chain management, and most of the companies are keeping the element of CSR into their account when purchasing from their suppliers (Maignan et al., 2002;Kolk and Van Tulder, 2002).

Role of relationship marketing orientation
One of the primary motives behind this is the pressure from customers who tend to be concerned with the suppliers of the corporation (Bartley, 2007). A firm directly or indirectly uses the suppliers' products as its end-products; therefore, customers' perceptions may be affected by the activities of the suppliers (Hietbrink et al., 2010). Thus, it is argued that customers' concerns can be addressed in suppliers' CSR activities. To support this argument, many scholars asserted that customer demand, personal conviction and ethical obligation can be addressed into supplier-related CSR activities (Carter and Jennings, 2004;De Ruyter et al., 2009). A large number of CSR studies have demonstrated that addressing the customers' concerns into CSR communications corporations can influence the behavioral intentions of customers. For example, CSR activities related to customers' concerns is more related to customers trust as compared to others which generate behavioral loyalty due to being directly connected with the customers' needs (Mandhachitara and Poolthong, 2011;Chung et al., 2015;Tingchi Liu et al., 2014;Badenes-Rocha et al., 2019). Corporations often try to incorporate customers' self-centered motives on a personal level in their strategies to influence their buying behavior. Recent studies found links between these two wellestablished concepts (Laczniak and Murphy, 2006;Ahen and Zettinig, 2015;Luu, 2019). Customer value co-creation behavior is twofold: customer participation behavior and customer citizenship behavior (Yi and Gong, 2013). By incorporating customers' needs into mainstream strategies, companies can influence the factors of participation behavior for value co-creation (Bharti et al., 2014;Ida, 2017;Zhao et al., 2018). Similarly, researchers have suggested that CSR influences customer citizenship behavior (Lee and Yoon, 2018;Van Tonder and Petzer, 2018). Based on stakeholder theory and the above-mentioned premise, the following hypothesis is formed: H2. Supplier-related CSR activities positively affect (a) customer participation behavior and (b) customer citizenship behavior.
2.3 Relationship marketing orientation as a mediator between local community-related corporate social responsibility activities and customer value co-creation behavior Customers are the operant resources or source of knowledge and skills for value co-creation (Vargo and Lunch, 2004). For effective value co-creation, interaction between consumers and service providers is necessary (Vargo and Lusch, 2008). This point highlights how RMO deepens the facets of CSR and customer value co-creation behavior under the stakeholder theory. According to this bilateral relation, customers must be a fundamental operant resource for value co-creation behavior (Vargo and Lusch, 2004;Gohary and Hamzelu, 2016). It can be argued that relational activities and interaction can convert customers into dynamic operant resources for corporations (Vargo and Lusch, 2011;De Chiara, 2012). Consequently, this type of planned orientation can tighten the relationships between corporations and customers (Morgan and Hunt, 1994) and ensure that maximum benefits are reap by the customers from CSR activities (Gohary and Hamzelu, 2016). When a company engages local community-oriented CSR, it builds relationships with customers due to positive evaluation which further extends trust, respect and care to customers (Tse et al., 2004). Once customers evaluate a corporation positively, they are committed for exchange including value co-creation. Through CSR activities, customers will notice that the corporation shares a common goal and values with them which help to enhance their connection with the socially responsible organization for value co-creation through communication (Abugre and Nyuur, 2015). The element of empathy in RMO also differentiates the socially responsible organization in the eyes of the customer (Tse et al., 2004). Reciprocity is the element of RMO which enables customers to collaborate and SJME 24,3 respond to the organization (Jayachandran et al., 2005). All six dimensions of RMO play a significant role in linking CSR community and customer value co-creation behavior. It can be assumed that RMO may serve as a mediator between CSR community and customer value co-creation behavior. This leads to the third hypothesis, which is: H3. RMO is a positive mediator between local community-related CSR activities (a) customer participation behavior and (b) customer citizenship behavior.
2.4 Relationship marketing orientation as a mediator between supplier-related corporate social responsibility activities and customer value co-creation behavior In mainstream marketing studies, the literature on relationship marketing has ignored the importance of the other stakeholders besides customers. Thus, in relationship marketing approach, there is a growing consensus to focus on other stakeholders, along with customers, in the network (Payne et al., 2005;Gummesson, 1999). Relationship marketing focuses on how to create ongoing value-in-use, as opposed to only considering how to build relationships with customers (Payne and Frow, 2017). Relationship marketing orientation can be defined as the degree to which a firm is involved in developing long-term relationships with its clients (Tse et al., 2004). Sin et al. (2005) elaborated relationship marketing orientation (RMO) in more detail: trust, communication, empathy, shared value, reciprocity and bonding. Trust explains the preparedness to have faith in a partner on which a person can rely on with confidence (Morgan and Hunt, 1994). The communication facet refers to the sharing of official or unofficial timely and meaningful information between buyers and sellers. The element of empathy allows a person to see a situation from the stance of other people. The fourth is shared values which explain the extent to which partners believe commonly in policies, behavior and appropriateness (Morgan and Hunt, 1994). Reciprocity highlights a process that helps the customer to relate and share data within the organization and enable it to respond to the consumers' needs (Jayachandran et al., 2005). The last facet is bonding: that discusses emotional improvement between two bodies that act in unified manners for a common cause (Sin et al., 2005). The tendency of the relationship in CSR suppliers and customer value co-creation might be intensified by the related actions of the organization and in this way, RMO may serve an influencer. Relationship marketing orientation can help to drive the suppliers to further connect with the organization and its CSR value and stimulate the customer for active participation in the entire process (McColl-Kennedy et al., 2012;Tse et al., 2004). The RMO is a further investment of corporations to strengthen the bonding with consumers for value co-creation that is also a form of reciprocity which is the outcome of relationship strategy (Tse et al., 2004). Every facet of RMO further encourages customers' perceptions about the CSR values of the organization which eventually leverage the reciprocal contribution from the customers in terms of value co-creation behavior. Thus, it is suggested that relationship marketing orientation can play a role as an intermediary force between suppliers-related CSR activities and customer value co-creation behavior (Figure 1).
H4. RMO positively mediates between suppliers-related CSR activities (a) customer participation behavior and (b) customer citizenship behavior.

Data collection and methodology
This research is conducted using cross-sectional survey to test the proposed relationships in the model based on the stakeholder theory. The primary data is gathered from the customers of twin cities Rawalpindi/Islamabad who maintain their accounts in the Pakistani Role of relationship marketing orientation banking industry. Islamabad is the capital of Pakistan and mixture of all societies due to educational hub and higher opportunities which is the best representative of Pakistani society. These responses gathered from banking industry as the problem of the disconnection between customers and management happen in this industry (Mujahid and Abdullah, 2014;Khan et al., 2014). To analyze the data, Smart PLS is used because the data fulfilled the assumptions of Smart PLS such as the sample size, etc. Although structural equation modeling can be run using a small sample size such as between 150 to 200 respondents, large sample size helps to establish better results (Hair et al., 2014) and the sample size of the present study fell beyond the recommended limit. In Pakistan, there are 34 operating banks (State Bank, 2016), and it is not possible to collect the data of all banks. These banks are categorized into three levels: small, medium and big banks based on market share, size, and total deposits. The researchers selected ten medium-size banks to be included in this study because these banks are more customer-oriented and strive to capture more market share (KPMG, 2015). This is because small size banks have less number of branches and cover limited geographical areas, while big banks have already huge share and are not aggressively customer-centric compared to medium size banks. The respondents are selected using purposive sampling. In Pakistan, only 16% of the total population have bank accounts (State Bank of Pakistan, 2016). The total population of Pakistan is 207 million (Pakistan Bureau of Statistics, 2017; Shahbaz, 2017), and the total banking customers are 30.1 million. Krejcie and Morgan (1970) suggested that if the population is more than 1 million, a sample size of 384 respondents is adequate. As much as

Measurement of instrument
The scales consist of five-point Likert items that ranged from strongly disagree to strongly agree. Five-item scale measured the independent variable -CSR local community, and a four-item scale measured the independent variable -CSR Suppliers. Six dimensions of relationship marketing orientation, namely, reciprocity, communication, bonding, empathy, trust and shared value, are measured by a 22-items scale. Two dimensions of customer value co-creation behavior, the dependent variable; customer participation behavior and customer citizenship behavior are measured by a 30-item scale. The scales for measuring the variables are adapted from literature which is given in the following table. In scale, the statement of items exactly measures the dimensions of CSR, relationship marketing and customer value co-creation behavior. For example, "My bank is supporting local sport, cultural or other community activities and projects" measure the local community-related CSR. Similarly, "My bank incorporates the interests of their suppliers in their business decisions" related exactly measure supplier-related CSR. Other scales are also assessed in this way, and these scales are validated by multiple scholars. The CSR activities-related scales have been tested in banking sector by Pérez and del Bosque (2013). Similarly, relationship marketing orientation and customer value co-creation scales are validated by Mainardes et al. (2017) ( Table 1).

Measurement model
To test the theoretical model, the first step is measurement model which is known as outer model. From the very beginning, it is mandatory to check whether the constructs are formative or reflective. The evaluation criteria of the formative measurement model were different from the reflective measurement model (Hair et al., 2014). In the formative measurement model, internal consistency is not appropriate (Chin, 1998), due to the representation of the independent cause and having no correlation with each other. The

Role of relationship
marketing orientation reflective measurement model's items must be correlated and depict the true picture of the significant outer loadings. The reflective measurement model needs reliability and validity of construct, whereas formative measurement model needs convergent validity and discriminant validity. In the current study, all variables are reflective. Table 2 describes the composite reliability of the variables The value falls between the range of 0 and 1 where higher values of composite reliability describe higher reliability and the acceptable values fall between 0.60 and 0.70 (Gefen et al., 2000). Memon et al. (2018) proposed that 0.70 is considered as the standard for consistency. Table 4.1 shows that the value of composite reliability for all variables is above 0.70 that shows that all items are internally consistent. Outer loading indicates the reliability that shows the indent of measurement which is actually being assessed (Urbach and Ahlemann, 2010). The cut-off value for reliability is 0.50. This table also shows the AVE which is greater than 0.50 for all variables which shows that every variable must explain a minimum of 50% of the variance by the assigned items (Hair et al., 2017). Table 3 shows the discriminant validity and in the present study, the criteria outlined by Fornell and Larker (1981) are being followed where the squired root of the AVE on the diagonal must be more than the correlation on the off-diagonal. The following table describes that the values of all constructs are greater than off-diagonal values which means that there is no issue of discriminant validity (Figure 2). Table 4 explains the direct relationship of CSR activities on customer participation behavior and customer citizenship behavior. Local community-oriented CSR activities positively affect customer participation behavior as its t-values is 7.777 which is greater than 1.645 and significant at 0.05 level. Local community-oriented CSR also positively affects customer citizenship behavior and its t-values is 4.798 which is greater than 1.645 and significant at   Table 3. Discriminant validity of constructs SJME 24,3 0.05 level. The beta value is 0.390 and 0.337 for customer participation behavior and customer citizenship behavior, respectively. These beta values describe that if one-unit change occurs in local community-oriented CSR, there will be 39% change in customer participation behavior and 33% change in customer citizenship behavior. Supplier-oriented CSR positively affects the customer citizenship behavior as its t-values, 4.035, which is greater than1.645 and significant at 0.05 level. Supplier-oriented CSR also positively affects customer citizenship behavior as its t-values, 3.239, which is greater than 1.645 and significant at 0.05 level. The beta value of supplier-oriented CSR is 0.199 and 0.183 for customer participation behavior and customer citizenship behavior respectively. These beta values describe that 1 unit change in supplier-oriented CSR brings 19% change in customer participation behavior and 18% change in customer citizenship behavior.

Mediation analysis
The R 2 values are 0.272 and 0.182 which describe that two independent constructs, namely, CSR local community and CSR suppliers explain 27% variation in customer participation behavior and 18% variation in customer citizenship behavior. This table also highlights the effect size of both independent variables as the value of f 2 shows that local community-oriented CSR has 0.190 and 0.133 effect size for customer participation behavior and customer citizenship behavior, whereas the value of f 2 shows that supplier-oriented CSR has 0.049 and 0.039 effect size for customer participation behavior and customer citizenship behavior. Suppliers-related CSR activities have a smaller effect on customer value co-creation behavior as compared to local community-oriented CSR activities. So, H1a, H1b, H2a and H2b are supported (Figure 3).  Role of relationship marketing orientation Table 5 describes the direct and indirect impact of local community-oriented CSR and supplier-oriented CSR on customer value co-creation behavior via RMO. The beta value of H3a, H3b, H4a, and H5b are 0.276, 0.240, 0.128 and 0.114, respectively. The direct effects are statically significant as its t-values are above 1.64 (Hair et al., 2017). The beta value of H3a, H3b, H4a and H4b are 0.102, 0.093, 0.075 and 0.069 in the in-direct effect are statistically significant as its values are greater than 1.64 (Hair at el., 2017). It means that relationship marketing orientation partially mediates CSR activities and customer value co-creation behavior. The beta values H3a, H3b, H4a and H4b decreased from 0.276, 0.240, 0.128 and 0.114 to 0.102, 0.093, 0.075 and 0.069 in the in-direct effect, respectively. So H3a, H3b, H4a and H4b are supported. Table 6 highlights the strength of mediation between CSR activities and value cocreation. If a direct link is not significant, then there is no mediation and if a direct link is significant, the VAF (Variance, Accounted For) is conducted to check the strength of mediation (Wong, 2016;Hair et al., 2014). If the value of VAF is greater than 80%, it shows

Conclusion
This study aimed to check whether customized CSR activities for local community and suppliers are useful to integrate into the model to generate the value co-creation behavior within the Pakistani banking industry. The present study has proven that local communityoriented activities have a positive role in customer participation behavior and customer citizenship behavior. It shows that CSR is not only important for customers' perception but also works as a driving force for customer value co-creation behavior. This community dimension of CSR is a strategic marketing tool through which banks can add more customers in their pool and advocate their messages in the right direction without additional cost. This finding is aligned with previous studies that show that customized CSR action can shape the behavioral outcomes of customers (Arli and Tjiptono, 2018;Chung et al., 2015;García-Madariaga and Rodríguez-Rivera, 2017). Similarly, supplier-related CSR communications positively affect customer participation behavior and customer citizenship behavior. Focusing on CSR for suppliers, banks can influence the customers' observation because customers are either directly or indirectly the end-users of suppliers' related activities. This study is the first to incorporate the supplier-focused CSR activities in a model to unstructured the customer value co-creation behavior. This study also demonstrated that relationship marketing orientation partially mediates between local community-oriented CSR and customer participation behavior and customer citizenship behavior. RMO also mediates between supplier-oriented CSR and customer participation behavior and customer citizenship behavior. This finding strengthens the outcomes of the study conducted by Luu (2019) that suggested that RMO play a constructive role between CSR and customer value co-creation behavior. With the help of RMO, banks can improve the prospects of qualityoriented contact between customer and service providers in the banking industry of Pakistan.

Theoretical implications
This is the first study that applied stakeholder theory to explore the non-economic value of stakeholders: customer value co-creation behavior. Based on stakeholder theory, most CSR studies strived to assess the behavioral outcomes of the customer concerning the most important stakeholder and missed other imperative stakeholders. Stakeholder theory is also related to the value maximization and the interest of stakeholders, but there are limited number of studies that incorporate importance external stakeholder, i.e. Role of relationship marketing orientation suppliers to study the customer value co-creation behavior. This study has extended the CSR literature with customer value co-creation behavior under the head of stakeholder theory and service dominant logic. This work contributed into the deficiency of service dominant logic by introducing RMO that explains the interaction between customers and service providers is mandatory for effective value co-creation behavior. Through this lens, it has proved that along with customers, other stakeholder such as local community and suppliers can generate customer value co-creation. Previously stakeholder theory has been used for maximization of shareholders' wealth and did not discuss value co-creation, but the present study applied first time this theory for non-economic value of customer process that lessens the criticism on narrower part of this theory. The findings increase the understanding of value process by connection of three different concepts: CSR, RMO and customer value co-creation behavior. 5.1.1 Managerial/practical implications. This research has several managerial implications for the Pakistani banking industry. The results offer insights for the executives of banking that CSR local community bank do not only contribute to the society but also stimulate customers for active participation. This is because community related CSR activities are closely related to customers, and they can easily notice them due to its tangibility. Similarly, banks must focus on supplier-related CSR activities to build customer value co-creation behavior. This is because supplier-related CSR activities indirectly affect the decision of customers as the end-users of products.
