Introduction
In the age of global hyperconnection, innovation, a fundamental pillar of company competitiveness, although investigated often and with different approaches, needs to be considered in the social process perspective (Hellstr€ om, 2004;Doh and Acs, 2010;Franz et al., 2012;de Melo et al., 2020).
Since digital technologies, digital platforms and digital infrastructures extended to macro, meso and micro levels, business innovation processes changed in significant ways, favouring collaboration and knowledge sharing among individuals, firms, other agents and the context (Nambisan et al., 2018(Nambisan et al., , 2019;;Malhotra and Majchrzak, 2019;van Wijk et al., 2019).
Even though, from a business viewpoint, collaborational approach has an important role in the development of every organisation, it appears to be crucial especially for those small firms that are engaged in developing innovation.Small firms often lack the abundance of resources (i.e.human capital, financial resources and so on) required to engage in sole complex innovative projects (Hannan and Freeman, 1984;Freel, 2000;Ko et al., 2020).Hence, collaboration represents a way to overcome this physiological lack of resources.Accordingly, as theoretical and practical evidence showed, the concept of innovation has been redefined, going beyond the boundaries of technology (i.e.new products/processes), since changes originate from all the elements comprising a firm's business model.Innovation moved on from the technology push theory (Freeman, 1994;Rothwell, 1994) to the market pull process (Rothwell, 1992;Brem and Voigt, 2009), continuing towards the coupling innovation process theory (Rothwell and Zegueld, 1985), a combination of the previous two theories, then followed by the functional integration innovation process theory (Imai et al., 1985) and the systems integration and networking innovation process theory (Dodgson et al., 2002).In sum, innovation has been progressively based on models of systems integration and open innovation (Chesbrough et al., 2006;Huizingh, 2011).In particular, open innovation has been defined as a new paradigm in innovation management (Chesbrough and Crowther, 2006).Open innovation emerged in the high-tech context, and it now affects several sectors and industries (Bughin et al., 2008).In short, open innovation refers to the formal and informal linkages of external collaboration in which an organisation engages with the actors of the ecosystem to foster its innovative performance (Scuotto et al., 2017a).Also, previous studies investigated the degree of openness to exploring new knowledge sources across organisation boundaries, contributing to expand existing internal knowledge with a higher level of innovation (Wang et al., 2020).Hence, the boundaries between internal and external sources of innovation disappear among the many and various actors in the innovative process.
In other words, the capacity for innovation does not exclusively lie within corporate contexts using a firm's own resources.It is nourished by external relationships, with the emphasis on cooperation (Katz et al., 2013) in the innovative process (Sisodiya et al., 2013;Salter et al., 2014;Rubera et al., 2015).The relational behaviour of the players involved is interlinked with knowledge resources (Hayter, 2013), from mere access to partners' knowledge platforms to the transfer of information and know-how to the co-production of new knowledge, requiring organisations to be increasingly complex (Klerkx and Aarts, 2013).Hence, by adopting a collaborative business model, innovation value is generated by a combination of complementary resources (Eppler et al., 2011;Eppler and Hoffmann, 2012;Rohrbeck et al., 2013).Inflows and outflows of knowledge are used to accelerate internal innovation and extend markets for the external use of innovation.On the one hand, new ideas flow into a firm in an inbound process of open innovation.On the other hand, the outbound process enables external organisations to acquire internally developed innovations and to commercialise them, thanks to more suitable business models (Brunswicker and Wim Vanhaverbeke, 2015).
Nevertheless, in this context, it is important to avoid the creation of exclusively pathdependent innovation knowledge from external sources.Thus, organisations should develop Italian small innovative enterprises internal capabilities and practical tools and systems to manage and integrate the different sources of knowledge, both internal and external (Ferraris et al., 2017).In this context, an interesting area of investigation examines the contribution of digital transformation-the process of exploiting digital technologies and supporting capabilities to create a robust new digital business model (Gartner, 2019)-to intra-and inter-organisational collaboration to help enterprises with their innovation.The existing literature has underlined specific aspects of digital transformation.Some authors focused on the organisational dimension, stressing the integration of digital technologies and business processes in a digital economy (Liu et al., 2011).Others analysed the changes digital transformation has brought to the business model, in the form of product innovation or organisational structures or the automation of processes (Hess et al., 2016).Some studies took into consideration the use of new digital technologies (social media, mobile devices, analytics or embedded devices) to enhance customer experience, streamline operations or create new business models (Fitzgerald et al., 2014).
Apart from the definition, the most relevant trait consists of the underlying strategic vision of the firms rather than the technologies applied (Warner and W€ ager, 2019).Indeed, the strategic orientation enables organisations to follow the needs of customers by using new digital technologies to handle valuable information.In this way, digitalisation has opened up a wide range of possibilities for firms to interact with stakeholders, especially regarding the search for novel solutions, new offerings or innovation processes.Digital technologies enable information sharing among the actors of a network or ecosystem of innovation (Del Giudice and Maggioni, 2014), supporting the process of knowledge acquisition, dissemination and exploitation (Scuotto et al., 2017b).In sum, digital tools support enterprises in acquiring and managing the intangible assets of firms, such as intellectual capital (IC), concerning the distinctive knowledge, abilities, values and methods of a firm (Bayraktaroglu et al., 2019), in a social manner, to promote innovative ideas, products and processes.In this vein, social innovation capital (SIC) is a particular kind of IC, which refers to the collective capacity of a firm to innovate, underlying its fundamental aptitude to learn, innovate and adapt (McElroy, 2002), thereby generating competitive advantages.The recognition of the significance of SIC in firm performance and competitiveness requires its active support and management.
In that sense, the aim of the paper consists in understanding whether and how firms can engage in collaborations with their partners to enhance their ability to acquire and exploit knowledge to generate innovation.In particular, the study contributes to better clarify the role collaborationÀin terms of collective capacity to innovateÀplays in the context of small innovative enterprises (SIEs), extending the current knowledge about how this particular kind of organisation could enhance their capability to innovate by exploiting and reinforcing their SIC.In particular, the study aims to shed some light on the contribution that the resource sharing and the sharing intensity offer to the generation of SIC.
Furthermore, the study takes into account the contribution that digital patterns, in terms of digital tools adopted by firms, could add to the radical shifts digitalisation generates.Digital tools support innovative projects, enabling firms to provide mutual support, enhancing conversation among partners and reinforcing relationships.Hence, the research enriches the existing literature on SIC, by applying digitisation as an effective resource for innovation, instead of a mere context of or tool for innovation.On this vein, the study clearly underlines the mediating role of the digital patterns on the SIC of the SIEs.
The present study aims to add to the present understanding of SIC by investigating digital transformation in terms of digital collaboration.This paper, performed in the particular research setting of Italian SIEs, characterised by being strictly engaged in the innovation processes, despite a feasible limitation of means, and by having higher-level human capital.These peculiarities constitute a trait of interest to investigate on SIC development.Hence, the study contributes to the recent debate regarding SIC by providing a better explanation of whether and how digitalisation, in terms of digital collaboration and digital tools, supports SIEs in developing their SIC.In sum, the focus of the study is on the joint efforts with partners to achieve common goals, the digital tools that favour these practices and their effects on SIC.
Therefore, to better underpin and enhance these considerations, the paper is structured as follows.The second section, succeeding the introduction, reflects on the effects of digital transformation on SIC, showing the main realms of IC, social capital (SC) and SIC research.Also, the principal constructs underlying the research objectives are highlighted.The third section describes the research design used for the empirical analysis, the research hypothesis and data collection on a sample of 82 SIEs in Italy.Next, the results of the online survey are presented and discussed, highlighting the emerging business model for innovation applied collaboratively by the SIEs and the effective contribution of the digital tools used.These considerations encourage the evaluation of the emergence of a more updated measurement of SIC, which considers spread and effectiveness of digital tools, contributing to the innovation value creation, value proposition and value capture of SIEs.To conclude the paper, theoretical and managerial implications and limitations are outlined, together with some recommendations.Therefore, considering the collaborative approach, the paper offers a fresh perspective on the role of SIC in supporting more effective innovative performance in Italian SIEs.

Context of analysis
As shown in several studies, unlike big corporate enterprises, SMEs are more eager to build efficient and durable relationships in their ecosystem to develop intangible resources (human, technological and knowledge) to convert them into value and innovation (Parida et al., 2012).Among them, a cluster of interest for the present analysis is represented by SIEs.According to Italian legislationÀDecree-Law 3/2015, known as "Investment Compact" and converted into Law 33/2015Àa broad range of companies beyond innovative start-ups are considered to be "innovative SMEs", regardless of the sector, provided they are characterised by an explicit innovation content (Italian Ministry of Economic Development, 2019).These SMEs need to respect some requirements: being incorporated as limited companies, including cooperatives; having their headquarters in Italy or in another Member State of the European Union or of the European Economic Area; having a production facility or branch located in Italy; having their latest financial statements drawn up by an auditor or an audit firm recorded in the register of auditors; not having shares listed on a public regulated market and not being registered in the special section of the Business Register dedicated to innovative start-ups and certified incubators.Also, these firms need to fulfil at least two of the following criteria: (1) Research and development expenditure corresponds to at least 3% of the higher value between turnover and annual costs (as per the latest approved financial statement); (2) At least onefifth of the total workforce is made up of PhD holders, PhD students or researchers or at least one-third hold a master's degree; (3) The company is the owner or licensee of a registered patent (or it has filed an application for an industrial property right) or it owns original registered software (Italian Ministry of Economic Development, 2019).Finally, these firms can obtain the status of innovative SMEs by registering in a special section of the Business Register created ad hoc by the Chambers of Commerce.Hence, despite a feasible limitation of means, these companies distinguish themselves from other organisations in the market by being strictly engaged in innovation processes and by having higher-level human capital.

Theoretical background and study hypotheses
In the enterprises mentioned above, innovation constitutes a deoxyribonucleic acid (DNA) trait, allowing the enterprises to accumulate knowledge and technological capacities, to improve productivity, to reduce costs and to improve competitiveness.Much of the innovation generated by these firms depends on intangible assets and on the knowledge they possess or may be obtained from external contributions.In other words, internal knowledge Italian small innovative enterprises (such as the competences of employees), attitudes, aptitudes, intellectual agility, good relations or the ability to generate them, and adequate organisational technology, affect the capacity of the firm to achieve sustainable success (Mariz-Perez et al., 2012).The literature on the topic refers to the interaction of the various classes of intangibles as IC or the knowledge that is valuable in an organisation (Campanella et al., 2014).This knowledge commonly consists of three elements: human capital, organisational or structural capital and SC (Dost et al., 2016).However, several resource barriers to engaging in innovation are widely recognised, especially for SIEs.Some innovative SMEs suffer more than other companies from lack of physical, organisational and financial resources.They can lack adequate resources to exploit their knowledge stock.Also, they experience a higher level of complexity in attracting the best professionals and in optimising their technology.Unlike their larger competitors, SIEs have difficulty launching big innovation projects due to the level of resources required.This difficulty can arise despite the investment of a considerable portion of their budgets in research and development (R&D), often at the expense of other business activities and requiring increased risks.The exploitation of external knowledge may constitute a good opportunity for SIEs to overcome these obstacles (Kearney and Mchattie, 2014), allowing access to the intangible assets of partners, thanks to more or less formalised relations.Previous studies on SMEs demonstrated that proficiency in applying open innovation by collaborating with network partners could help these firms to develop new technological combinations, and thus address or take advantage of more market opportunities.Also, by exploiting technology developed elsewhere, SIEs can fill in their internal technological gaps and increase the speed and quality of innovative activities (Parida et al., 2012).In this manner, SIEs may fill the gap between required and available resources for the innovation process.
Digital transformation may facilitate this approach.Hence, the paper attempts to identify the elements of IC that contribute to guaranteeing the collective innovation capacity of SIEs, paying special attention to digital collaboration on SIC.

Intellectual capital
IC is a multi-dimensional concept linked to knowledge, experience and the practical capabilities of a company.Its effective management can help a company to improve its position in the competitive arena.All the purely intellectual assets that a firm owns that can be used to achieve competitive advantages are recognised as components of the IC (Stewart, 1997;Sullivan, 1998;Hussinki et al., 2017).Many studies conducted on different sectors and countries underlined the contribution of IC to firm performance and value creation (Ulum et al., 2014;Vishnu and Gupta, 2014;Hashim et al., 2017;Sardo and Serrasqueiro, 2017;Bayraktaroglu et al., 2019;Xu and Li, 2019).Value creation consists of the shaping of information, knowledge and innovation.E-commerce, for instance, in the early stages, represented a new type of value transaction based on the shape of value constellations with temporary role participants and high growth potential (Edvinsson, 2000).
Hence, going beyond the definition of Edvinsson and Malone (1997), identifying the two main elements in IC, human capital and structural capital (Petty and Guthrie, 2000), IC is traditionally viewed as having three components (Buenechea-Elberdin, 2017;McDowell et al., 2018).The three components are as follows: (1) human capital, the resources created from the stock and flow of knowledge shared among employees within a firm (Marimuthu et al., 2009); (2) structural or organisational capital, defined as the extraordinary value created by intangible assets, practices, databases, leadership, strategy and organisational design enabling optimal resource orchestration (Miles and Van Clieaf, 2017); (3) SC, the resources derived from the network of relationships possessed by an individual or a social unit (Nahapiet and Ghoshal, 1998).Some studies also include renewal capital (Kianto, 2008), entrepreneurial capital (Erikson, 2002) and trust capital (Mayer et al., 1995).Due to its link with value creation (Chang and Hsieh, 2011), there is a connection between IC and innovation (Subramaniam and Youndt, 2005;Campanella et al., 2014;McDowell et al., 2018), as shown in Table 1.
In sum, an organisation's innovation process depends, to a great extent, on a firm's knowledge base and on the knowledge that a firm can generate in its internal and external networks that constitute the SC of a firm.

Social capital
The unstoppable assimilation of the social dimension in business and individual activities is a characteristic trait of the knowledge society.Therefore, many scholars examined the impact of relational actions on firm performance, aiming to identify and evaluate the intangible assets capable of increasing the market value of a firm (Bueno et al., 2004).These assets are known collectively as SC.Therefore, SC is a component of IC, and it is based on the resources accumulated in the organisation from a stable network of intra-organisational relationships (Bourdieu and Wacquant, 1992) also in potential terms (Nahapiet and Ghoshal, 1998).SC also includes the social structures that facilitate activity in the network.The emerging network of collaborative relationships favours the development of new knowledge, thanks to the attitude to sharing knowledge (cognitive dimension) between the actors, perceiving themselves as a part of a network (structural dimension), with a sense of confidence and mutual obligations (relational dimension) (Kim and Shim, 2018).Therefore, SC involves a set of values and subsequent indicators like trust, confidence, loyalty, sincerity, compromise, transparency, solidarity, responsibility, honesty and ethics (Prusak and Cohen, 2001;Bueno et al., 2004;Camps and Marquez, 2014).
When revising the relational capital approach, based on the value of the set of relationships between the firm and its environment, SC considers three categories: intra-SC, in terms of personal relationships within the firm, arranged in communities (virtual or not); inter-SC, referring to the relationships with clients and shareholders and SIC, focused on the dynamic, flexible set of processes and relationships that guide innovation (McElroy, 2002).Moreover, the management of the intrinsic risk and uncertainty involved in collecting and

Social innovation capital
The collective capacity to create valuable, rare and inimitable knowledge (Barney and Hesterly, 2010) and the practice of sharing it among different actors have received increasing emphasis in the analysis of innovation business models (Alguezaui and Filieri, 2010).
According to the SC theory, trust, reciprocity, shared values, networking and norms affect this capacity, empowering a feature relevant to IC (Birudavolu and Nag, 2019).In this context, the concept of SIC was introduced in the literature (McElroy, 2002) as a specific component of SC, taking into consideration the collective capacity of a firm to innovate.Making full use of individual and collective knowledge, and in consideration of the dual nature of the focal actor (individual/organisation) creating/using/sharing knowledge (egocentric vs socio-centric perspective- McElroy et al., 2006), "SIC refers to the structural manner in which social systems (i.e.firms) organise themselves aroundand carry outthe production and integration of new knowledge" (McElroy, 2002;Young, 2012).In this perspective, SIC constitutes the source of most of the other forms of SC traceable in a company.Therefore, to comprehend how SIC makes a practical contribution to innovation, it is interesting to analyse patterns of collaboration.The character of a network can reveal archetypical social patterns, with their own tell-tale identity, whose purpose is to produce, spread and apply new knowledge (McElroy, 2002).Communities of practice, for example, as self-organising systems informally bound by what members do together, have an archetypical pattern, characterised by a continually renegotiated joint enterprise.These systems are relationships of mutual engagement uniting members in a social entity and a shared repertoire of communal resources, such as routines, sensibilities, artefacts, vocabulary and styles.Finally, even when answering to an external mandate, it is the community-not the mandate-that produces the practice (Wenger, 1998;Wenger and Snyder, 2000;Duguid, 2005).In the present work, within different kinds of self-organised groups (i.e.networks of practice, open work teams, relationships with suppliers, customers, competitors or business partners with areas of common interest), the policies of management of new knowledge (in terms of production and inclination to share knowledge and spreading of benefits) and of connectedness (technology infrastructures, platforms and digital tools for collaboration) are of particular interest in evaluating the enhancement of SIC in SIEs.
Previous studies suggest that knowledge is critical for a firm to succeed (Grant, 1996).Several theories of firm behaviour have tried to explain the shift from closed to open innovation models and the crucial role played by knowledge sharing and knowledge acquisition in enhancing competitiveness.With specific regard to knowledge sharing, that is the process of interaction, communication and coordination of knowledge (Wang et al., 2014), open innovation encourages access to knowledge among partners since it appears to be as a valuable input.Knowledge sharing potentially supports innovation throughout the whole organisation.In the case of knowledge acquisition, transaction cost of economics theory indicates that firms' activities could aim to achieve minimum production and transaction costs (Williamson, 1989).Therefore, firms could decide not to develop new knowledge internally but to collaborate with external partners or to outsource knowledge for cost-saving reasons (Hagedoorn, 1993).Another stream of research advises that firms do not necessarily need to rely on internal knowledge (Barney, 1991;Lavie, 2006).Firms aiming to reinforce their competitive advantage and succeed in a competitive arena, especially in current fast-changing scenarios, could adopt external sources to gain information that could enhance their innovativeness (Brachos et al., 2007) and performance (Wang et al., 2014).Specifically, when obtaining knowledge from several sources, it becomes relevant to analyse the breadth of the search, that is the extent of the search for external knowledge, and the depth of the search, in terms of the intensity of the relationship with each knowledge source (Santoro et al., 2019).This is because firms simultaneously engaged in the depth and breadth of an external knowledge search are more likely to be innovative (Wang et al., 2020).Accordingly, in the current study, considering the search breadth as the propensity to share resources and the search depth as sharing intensity between firms, two research hypotheses can be developed as follows: H1.The propensity to share resources positively affects the SIC-based performance of SIEs.
H2.The sharing intensity positively affects the SIC-based performance of SIEs.

Digital collaboration and digital tools
The innovative processes of companies depend, to a large extent, on their capacity to collect and use knowledge from several sources (Del Giudice et al., 2014).Recent studies focussing on SMEs have highlighted the fact that the adoption of different forms of IT may positively affect innovation performance.This is because IT infrastructures seem to play an essential role in supporting knowledge sharing processes (Soto-Acosta et al., 2014a, b, 2017;Mazzucchelli et al., 2019).From this perspective, the tools of digital collaboration, such as applications, social network platforms, blogs, web portals for intra-/inter-firms collaborations, could provide significant reinforcement to shared flows of knowledge, contributing to the generation of new knowledge.Therefore, firms should consider digital transformation as a value network question, giving them access to a wide range of digital systems to manage their interactions with different actors in their networks (Ferreira et al., 2019).SIEs capable of developing or managing strong digital collaboration tools can establish better relationships with both internal and external partners, enhancing their ability to innovate.Digital tools for the collaboration of individual workers can lead to new competences and prospects; at a firm level, they provide practical, professional and identity support.Enterprise social software-an integral part of companies' enterprise collaboration systems-with social features including subscribing (following) information or people, commenting or tagging contributions, and so on, are often equipped with extensive "awareness features", which help to recognise new and relevant content (Shubert, 2019).Also, platform-based interactions can help to identify potential consumers (recognised as critical resources for innovation), and, if their motivation is increased, the value of their participation is heightened (Eiteneyer et al., 2019).For instance, user-generated content on social media and online communities represents a form of disruptive cooperation that has substantial potential benefits for the future growth of society.Sales, marketing and the provision of community insights are among the multiple uses of social media (Brem and Bilgram, 2015).Social media can be used as a tool for communication or to develop customer relations management.From the innovation standpoint, social media can facilitate information and knowledge sharing in online communities, especially in relation to product information and customer experiences.Above all, this kind of knowledge is useful in inspiring new product development and idea generation (de Zubielqui et al., 2019).In short, digitisation-and digital tools favouring collaboration accordingly to the present study-does not merely represent the context for innovation.On the contrary, digital technologies can assume the role of an operant resource, serving as an active ingredient in fuelling innovative initiatives (Nambisan et al., 2019).Therefore, digital tools can be effectively employed to connect resources, knowledge and capabilities among stakeholders, customers and other organisations, and they can have a critical role in facilitating the interdependencies and knowledge flows that occur in the collaborative innovation processes (Muninger et al., 2019).The knowledge sharing generates the requisite knowledge to transform ideas into innovation outcomes.Therefore, the role of digital tools needs to be deeply analysed, as characteristic collaborative patterns emergenarrowing the choice of digital patterns of collaboration in the present study-in accordance with the SIC viewpoint.
From such a perspective, a further two research hypotheses can be developed as follows: H3.The higher the digital patterns, the higher is the effect of shared resources on the SIC of the SIEs.
H4.The higher the digital patterns, the higher is the effect of sharing intensity on the SIC of the SIEs.
A conceptual model has been constructed, taking into account the hypotheses mentioned above.The model is presented in the diagram below (Figure 1) and illustrates the relationships investigated.

Research sample and data collection
The study aims to investigate the effects of digital transformation within the SIEs' frameworks.In particular, the paper tries to understand better whether and how firms' propensity to share resources with partners to achieve common goals, the sharing intensity and the digital collaboration, affect SIC.The study uses a quantitative approach to achieve this aim.In particular, a multiple regression analysis is performed to test the hypotheses on data retrieved from a sample of Italian SIEs.The authors consulted a special section of the Business Register of the Italian Chamber of Commerce to identify SIEs for inclusion in the sample.In particular, the pminnovative.registroimprese.itplatform, launched in November 2015 and publicly available, allows firms that fulfil specific requirements to register as innovative enterprises at their local Chamber of Commerce to benefit from a vast array of Conceptual model policy measures.This particular section of the Italian Chamber of Commerce website provides a complete business profile of innovative SMEs, updated or confirmed at least once a year (as confirmation of compliance with legal requirements).At the end of November 2019, 1,301 innovative SMEs (excluding innovative start-ups) were registered on the platform, 1,033 of which were classified as SIEs, since they had fewer than 50 employees and a total turnover not exceeding V10m (www.pminnovative.registroimprese.it).This subset of Italian SIEs represents the initial database for the present study.After a preliminary screening of the websites of SIEs, it emerged that 327 firms did not declare a contact email address, so the effective database was made up of 706 SIEs.From December 2019 to January 2020, these SIEs were invited to reply to the questionnaire, and 91 questionnaires were returned in a completed form (12.88% response rate).The research aim is to investigate whether and how SIEs collaborate with partners and exploit the potential of digital transformation to achieve common goals and reinforce their SIC.Nine questionnaires were eliminated because they were incomplete or were from firms declaring non-adoption of digital collaboration.The remaining 82 SIEs make up the final sample of the present study.The questionnaire, in which respondents self-reported their answers, was developed according to previous literature on firms' collaboration, social media digital collaboration, and SIC by focussing on and adapting the scales and key indicators in questionnaires used in previous studies.In particular, the online questionnaire was structured in two sections: the first part was used to collect data about the investigated variables to examine the existing relationship among them and to obtain information on the research topic; the second section collected information about the investigated SIEs, such as field of activity, sales revenue and business form.Additionally, to reduce the risk of common method bias, throughout the data collection process, respondents were not informed about the aim of the study, and the dependent and independent variables were presented to interviewees in different positions in the questionnaires (Jahanmir and Lages, 2016).
As shown in Table 2, the majority of the interviewed firms are limited liability companies (8.4%), followed by limited companies (11%), individual companies (2.4%) and unlimited partnerships (1.2%).Regarding the target market, more than half of the firms operate at international level (54.9%), followed by those operating at national (36.6%) and regional levels (8.5%).Regarding sectors, firms providing services are the most numerous (57.3%), followed by manufacturing firms (32.9%) and, finally, the commercial services sector with the lowest percentage (9.8%).

Italian small innovative enterprises
Variables All measures of the independent variables, namely sharing resources, sharing intensity, and digital patterns, were adopted from previous studies to suit the research context better.They were evaluated on a seven-point Likert scale, ranging from 1 (strongly disagree) to 7 (strongly agree).
Regarding sharing resources, respondents had to evaluate their firms' intention to cooperate with other innovation partners in terms of sharing proprietary information, innovative ideas, market opportunities and intermediate goals preparatory to achieving the main results.This four-item scale was adapted from Richey and Autry (2009).The second independent variable, namely sharing intensity, was evaluated using a three-item scale adapted from Faems et al. (2005).Respondents had to evaluate their firms' readiness to set up innovation-related projects with partners, customers and universities and research centres, respectively.Finally, a third independent variable that works as moderator, namely digital patterns, was measured using four items adapted from Trainor et al. (2014) and provides a measure of firms usage of social media to develop innovative projects, sharing mutual support, establishing conversations and reinforcing relationships with partners.
The dependent variable, SIC, was evaluated using a four-item scale adapted from Kijek (2012).SIC concerns the capacity of a firm to organise itself around the generation and exploitation of new knowledge.Therefore, respondents had to evaluate firms' SIC by expressing an opinion about their firms' cooperation between research and development, production and marketing departments, their capacity to generate patents or patent claims, their propensity to exchange knowledge in the social environment and their incentives for innovative partners.
Additionally, based on the literature review, several control variables were included in the questionnaire to avoid bias.The size of a firm could significantly affect its ability to organise processes, allowing the creation and exploitation of knowledge; therefore, firm size was included in the analysis.This particular control variable was evaluated using annual turnover.Finally, the study takes into account the industry as a control variable because the field of activity seems to shape the usage of social media in developing innovative projects.The sector of activity variable was measured as a dummy variable for each industry: manufacturing, commercial services and services.

Measurement scale validation
Cronbach's alpha was calculated to assess the reliability coefficient of the variables adopted in this study (Hair et al., 2006) .The results show that all construct measures proved to be reliable or close to reliable, according to the commonly employed Cronbach's alpha cut-off value of 0.70 (Nunnally and Bernstein, 1994).Concerning the convergent validity test, the study checked item loadings, and they all turned out to be equal or greater than the recommended threshold of 0.50 (Hair et al., 2006); all the composite reliability (CR) values exceed the minimum threshold of 0.70 (Bagozzi and Yi, 1988;Nunnally and Bernstein, 1994).Finally, the average variance extracted (AVE) was checked, and the results confirm that all values are over the conventional threshold of 0.50 (Fornell and Larcker, 1981).Table 3 presents the reliability and CFA results.

Analysis and results
The study aims to examine three different models.In particular, the hypotheses were investigated by running a multiple regression analysis using Statistical Product and Service Solutions (SPSS) 25.The decision to adopt a quantitative technique to study the investigated topic and assess the survey data using an ordinary least squares (OLS) regression analysis appears to be appropriate and justified because previous studies have called for a more finegrained understanding of the contribution SIC could offer to firm innovativeness (McElroy, 2002).The choice to adopt a quantitative method was in line with the proposed research and with previous studies (Duodu and Rowlinson, 2019).It was based on the analysis of the relationship between sharing resources and sharing intensity (independent variables) and their effect on SIC (dependent variable).The OLS regression results are presented in Table 4.
With specific regard to model 1, exploring the direct effect of sharing resources and sharing intensity on SIC, results show a moderate goodness of fit (R 2 5 0.415).Model 1 shows a significant relationship between the firms' sharing of resources and SIC, as well as the intensity of the collaboration between SIEs and their partners and the level of SIC.Hypothesis 1 and Hypothesis 2 are both confirmed because the effect of sharing of resources on SIC is significant and positive (B 5 0.264; T 5 3.071; p < 0.01), and the effect of sharing intensity on SIC is significant and positive (B 5 0.312; T 5 4.213; p < 0.01).Model 2 was proposed to test the moderating effect of digital patterns on the relationship between resource sharing and SIC.The model shows an acceptable goodness of fit (R 2 5 0.449), and the moderating effect turned out to be positive and significant (B 5 0.056; T 5 2.140; p < 0.05), confirming H3.Finally, model 3 presents a moderate goodness of fit (R 2 5 0.437) and tests the moderating effect of digital patterns on the relationship between sharing intensity and SIC, which emerged as not significant (B 5 0.044; T 5 1.688), rejecting H4.
The models also indicate that firm size and industry have a significant effect as control variables.Specifically, firm size affects SIC positively, as shown in models 1, 2 and 3, while being in the manufacturing business affects SIC negatively.Finally, being in the commercial services industry seems not to have a significant effect on SIC.
Furthermore, since multicollinearity among independent variables could occur when performing multiple regression analysis, the authors checked for variance inflation factor (VIF).Since VIF statistics do not show values higher than five (Hair et al., 2010), multicollinearity is not a relevant problem, and it could be assumed that the models fit the data retrieved from the online questionnaire.

Discussion of the results
The contemporary information-rich competitive arena and the rapid growth of digital technologies require firms to continuously adapt to the evolving conditions of the environment, developing solutions that allow to generate and manage organisational knowledge.In this perspective, the resources firms generate and acquire from the networks wherein they operate and the structures that enable and accelerate activities among network members appears to be crucial for the knowledge generation and the competitiveness of the firms themselves (Kim and Shim, 2018).Since firms capacity to generate innovation relies on their networks more than ever (Del Giudice et al., 2014), firms are increasingly paying attention on how to develop and nurture their relationships with internal and external partners and, in turn, enhancing their performance and growth (Scuotto et al., 2017a).
In this sense, firms' digitalisation can be considered as an entrepreneurial process (Nambisan et al., 2018), capable of favouring the spread of knowledge within the firm itself and generating more updated business models that may not only erode incumbent advantages but also pinpoint new ways of producing innovation.
The study analysis highlights that the investigated SIEs, operating for the most part at international and national level, have a relevant use of intra-/inter-firm collaboration mediated by digital tools, principally social media, to share resources, both financial and intellectual, and stimulate widespread access to information via new technologies.Due to the technological progress brought about by digitalisation, firms seeking to survive have been adopting digital sources and patterns to find innovative solutions (Liu et al., 2011).In particular, today's competitive landscape requires firms to obtain information and learning from several sources and share knowledge to innovate and successful compete (Santoro et al., 2019;Wang et al., 2020).
On this view, these study results contribute to the recent debate regarding SIC, providing better explanation of whether and how digitalisation, in terms of digital collaboration and digital tools, could potentially support SIEs in developing their SIC.More in detail, SIEs propensity to share resources and their sharing intensity directly affect their SIC-based performance.Additionally, by adopting digital patterns as moderating variable, the study shows that the usage of social media to develop common projects with partners and provide mutual support allows to reinforce the effect that resource sharing has on improving SICbased performance.
From this perspective, the findings of this study confirm that, concerning SIEs, the propensity to spread resources and the sharing intensity positively affect the capacity to innovate.This result is particularly interesting because it confirms the important support digitalisation offers for the formal and informal linkages firms develop with other actors in the same ecosystem.This result also provides additional evidence of the centrality of the open innovation principle in the context of SIEs.The results also suggest that the effect of shared resources on collective innovation increases progressively as digital patterns grow, in terms of the tools utilised, while the connection is weaker for the resources sharing intensity.

Theoretical and managerial implications
The results of this research proffer potentially interesting implications from both a theoretical and managerial viewpoint, as they provide a better understanding of SIC, which represents one of the most important SC forms within a firm, and contribute to shed some light on the role digital patterns play in its generation.From a theoretical viewpoint, the study highlights the fact that digital patterns can be considered a key resource for the value configuration of the innovation activities of SIEs in the profitable selection of knowledge resources and favour-sharing information in promoting innovation and creating a competitive advantage.Furthermore, digital patterns can strengthen digital collaboration, contributing to the generation of joint innovation.In turn, this could impact the value creation process by favouring SIEs in the definition of improved value proposition, better starting offering, processes and organisational solutions.Additionally, digital patterns could increase the value generated for SIEs, resulting in more satisfactory use of financial, organisational and knowledge resources.Revenues could be increased as a result of a more appealing offer, more contained costs, better use of human resources and improved value capture.
Finally, digital patterns could favour the spread of value generated by conjoint activities among partners and in society-value spreading-in general, the activation of a virtuous circle.More competitive market positions, resulting from the innovation value process described above, encourage SIEs to pursue the improvement of the digital patterns adopted.The innovation value process, based on digital patterns, can help the supply side and the demand side in a virtuous mechanism of information/knowledge, transforming and renewing the innovative knowledge flowing among users thereby increasing market share, revenues, profitability and value for all the stakeholders involved, as shown in Figure 2.
The findings of this study enrich the existing literature on SIC by clarifying its competitive benefits for SIEs.Moreover, the study contributes to business management literature focused on investigating the processes, and, in particular, those who support firms in developing and managing knowledge (Del Giudice and Straub, 2011).This research helps to explain the issue of the business value of collaborative innovation, by underlining the mediating role of digital patterns, and by investigating the interplay of digital platforms and social media on attitudes to sharing resources.This result is particularly interesting because it adds to the literature investigating social media and the mechanisms through which social media tools contribute to the innovation generation process (Soto-Acosta et al., 2014b;Papa et al., 2018).This study contributes to management literature by offering new insights on the role digital patterns could have in supporting SIEs, a particular cluster of SMEs, in developing their SIC.Where the intensity of sharing is concerned, a decrease in shared resources as the firm became bigger was noted.This could be due to the fact that when SIEs attain better market positions, extend their business and increase in size, they can access other sources of knowledge.Also, on this stage these firms can find easier and quicker solutions to overcoming resource barriers in innovation.
The findings have practical implications, which are positive from a managerial viewpoint.Promoting digital collaboration by investing in social media and other sharing tools may help SIEs to locate physical, knowledge-related and financial resources.In this sense, social media are seen as enablers and drivers of innovation.Managers and entrepreneurs should  Italian small innovative enterprises encourage their employees to use social media tools, exploiting their capacity for real-time interaction to join intra-firm groups or communities of practice.The aim is to stimulate workers to intercept and exploit external knowledge, but also to deal with peers, to search for solutions to operative issues or to modify organisational routines or practices, which may have an impact on the way employees learn and operate in the innovation processes.Hence, turning to social media for digital tools promoting collaboration seems to be a change in SIEs' business model, which results in observable changes in their practices towards customers, employees and business partners.

Future perspectives of research and conclusions
SIEs can survive over time and transform themselves into incumbent firms if they can adapt to the environment and face the challenges of the current competitive scenario.Today, digital transformation appears to be not only a choice but a requirement to fully exploit the opportunities offered by the advent of the digital transformation.Among other factors, social media are increasingly becoming networking tools enabling companies to access knowledge from external actors to facilitate the innovation process and the firm performance (de Zubielqui et al., 2019).However, current research literature still offers little guidance on the strategic use of these tools (Muniger et al., 2019), and, as yet, does not promote their use as real digital patterns able to increase firms' innovative performance, especially in the case of small firms.Therefore, the present study aims to contribute to filling this gap by suggesting some implications to be addressed by SIC.Also, the findings may encourage companies to benefit from using social media throughout their innovation processes.However, even if the findings of this study elucidate the digital openings, it should be mentioned that these openings have their limitations, thereby suggesting avenues for future research.First, the sample size is limited, and the investigated firms are based in Italy.Only half of the sample operates in international markets.To validate the results, future research should try to enlarge the sample, paying attention to small, medium and big innovative companies and including firms operating in other countries.Then, future research could contribute to identify differences and commonalities with foreign markets and provide some interesting comparisons between firms of different sizes.Also, due to the young composition of the present sample, the effect of the age of firms was not taken into consideration.This effect could be analysed to evaluate the relationship between external knowledge search and innovation performance, as previous studies suggested (Li et al., 2019).Furthermore, this study only examines three macro-categories of sectors.It would be useful to perform an in-depth analysis to identify whether and how digital transformation contributes to generating and enhancing the SIC of firms.In addition, it would be useful to conduct other studies to compare and contrast the findings of firms engaged in sectors with significant use of digital tools with others that are less involved in new digital technologies.Finally, future perspectives of research may extend the conceptual model by taking into consideration the conditions under which knowledge flows via digital patterns among partners and measuring the effect of SIC on the innovation generated.Measuring could be financial and non-financial and could use structural equation modelling.
In conclusion, digital patterns can be considered as enablers to seize new opportunities and to update the existing business model by reconfiguring the process of value configuration, value creation, value capture and value spreading, thereby enabling access to knowledge assets, competences and complementary assets and technologies to achieve sustainable competitive advantages.
