In small-and medium-sized enterprises (SMEs), where typically the decision-making process is highly centralised, important decisions, such as open innovation (OI) adoption, will be strongly influenced by the characteristics of their Chief Executive Officers (CEOs). Pointing the attention to the strategic leadership and human elements, this paper sheds light on the micro-foundation of OI by emphasising the role that the personal traits of key individuals in innovation. OI adoption could result in the enactment of several OI modes -each representing an opportunity of potential change (of market, of technology or/and of the organisation) -and this paper attempts to examine the relationships between the CEO characteristics and each of the OI modes. Our analysis, using Korean SME data, shows that CEOs' positive attitude, entrepreneurial orientation (EO), patience and education can play important roles in facilitating OI in SMEs. However, this paper also observed that the effects of CEO characteristics on OI adoption were differently configured according to the nature of each OI mode, for example, CEOs' patience and EO had different impacts depending on the degree of uncertainty in the OI mode. This suggest that OI must be understood as a wide innovation spectrum, and, to increase opportunities for successful OI adoption, CEOs have to attempt to compensate for characteristics they may lack by recruiting appropriate complementary top managements. The research has practical implications for CEOs and policy makers who are interested in enhancing competitiveness of SMEs.

This paper attempts to deepen understanding of the relationship between open innovation (OI) and firm performance in small and medium-sized enterprises (SMEs). Based on survey data from 306 Korean innovative SMEs, the results of this study show that: (1) broad and intensive engagement in OI and cooperation with external partners are positively associated with firm performance; (2) technology and market-oriented OI modes (Joint R&D, user involvement and open sourcing), involving relatively low level of changes, can positively contribute to performance enhancement; and (3) innovative SMEs benefit from working with non-competing partners, such as customers, consultancy/intermediaries and public research institutes. This work has broadened the evidence available on SMEs’ OI adoption and has proposed a new way to study OI adoption and implementation.

The literature has shown that open innovation (OI) can be a winning strategy in improving firm performance. However, in order to adopt and implement it, managers need to resolve practical problems, such as understanding the role played by OI capacities and openness on firm performance. In response to these needs, this study aims to investigate the hierarchical relationships between openness, OI capacities and performance using a structural equation model approach. This paper also attempts to compare the levels of openness between firms in different industries to discover similarities and differences in OI phenomena. The analysis of data obtained from a survey of Korean firms shows significant interrelations between openness, OI capacities and firm performance. Our results go further in developing understanding of the building blocks on which successful OI is built and particularly suggest that desorptive capacity which underpins the out-bound OI process, is in turn strongly supported by knowledge management capacity. It is hoped that the results of this study can enrich our understanding of the OI mechanism and provide managerial and policy implications. ARTICLE HISTORY

Many studies have attempted to investigate the potential benefits of open innovation. However, the long term effects of openness have yet to be demonstrated, even if few researchers hypothesised that high openness could increase firms' dynamic capabilities and hence their resilience in the face of adversities, such economic downturns. Hence, this paper attempts to investigate this dynamic relationship between openness and firm performance with particular considerations addressing the recent financial crisis in 2008. Based upon the UK Community Innovation Survey (CIS) panel data collected between 2006 and 2012, this study finds evidence that supports the positive influence of openness on long-term firm performance. The results show that (1) increasing a firm's openness is an effective way of enhancing its dynamic capability and hence its resilience, and (2) of all the various configurations of openness, the collaboration with partners outside the firm's value chain and international partners have the highest impact on turnover recovery, as they will increase the chances of acquiring newer knowledge, which in turn will help firms to identify new opportunities to achieve sustainable growth. The findings of this paper have some practical implications for managers and policy makers.

Open innovation (OI) is an approach which describes a purposive attempt to draw together knowledge from different contributors to develop and exploit innovation. It has become clear that OI directly benefits organisations' economic performance and resilience, but researchers, practitioners, and policy makers became also convinced that OI might be the way forward to tackle the world’s most pressing societal challenges, representing unresolved Grand Challenges, which can only be weathered by diverse sets of collaborative partners that join forces. Although anecdotal evidence points at how OI practices can be employed to achieve societal impact not only in private firms but also in public organisations, very little understanding exists ‐beyond anecdotal‐ to link OI to societal impact. This special issue has the ambition to start the discussion and establish a framework as the stepping stone to tackle this complex research gap.
