Open innovation (OI) has been appointed as a key factor to promote innovative performance, but some research gaps remain especially when it comes to SMEs in developing countries. This article deals with (1) the effect of formalization of innovation strategy on OI activities in SMEs, (2) the impact of OI activities on SMEs’ innovative performance, and (3) the moderating role played by control on the relationship between inbound and outbound activities and the innovative performance. OI encompasses a range of innovative methods and procedures in firms to stimulate internal innovation and widen the external use of innovation (inbound and outbound). In this work, an empirical study is carried out on 543 Ecuadorian SMEs. The results show that the formalization of the innovation strategy promotes OI activities, both inbound and outbound. While outbound activities carried out by SMEs enhance innovative performance, this positive effect is only identified for inbound open innovation activities when control exists and increases, acting this variable as a moderating factor. These results have important implications both for the management of companies and the development of public policies aimed at promoting OI in SMEs in developing countries. This research contributes to the literature as it deals with a developing country context and considers a wide range of OI activities.

Management scholars and practitioners emphasize the importance of the sizeand diversity of a knowledge worker's social network. Constraints onknowledge workers' time and energy suggest that more is not always better.Further, why and how larger networks contribute to valuable outcomesdeserves further understanding. In this study, we offer hypotheses to shedinsight on the question of the diminishing returns of large networks and thespecific form of network diversity that may contribute to innovativeperformance among knowledge workers. We tested our hypotheses using datacollected from 93 R&D engineers in a Sino-German automobile electronicscompany located in China. Study findings identified an inflection point,confirming our hypothesis that the size of the knowledge worker's egocentricnetwork has an inverted U-shaped effect on job performance. We furtherdemonstrate that network dispersion richness (the number of cohorts that thefocal employee has connections to) rather than network dispersion evenness(equal distribution of ties across the cohorts) has more influence on theknowledge worker's job performance. Additionally, we found that thecurvilinear effect of network size is fully mediated by network dispersionrichness. Implications for future research on social networks in China andWestern contexts are discussed.

International joint ventures (IJV) are an important organizational mode for expanding and sustaining global business and have been of special relevance for the emerging Chinese market for decades. While IJVs offer specific economic advantages they also present serious management problems that lead to high failure rates, especially in developing countries. Because of the strategic relevance of IJVs and corresponding management challenges, research on success factors for managing IJVs in China has received broad attention, resulting in a variety of studies. However, there are no conceptual syntheses of the literature to date and further development in the field is hampered by both a lack of consolidation of what is known and identification of viable avenues for future research. We address this gap by building on existing concepts in the field, developing them further and synthesizing them into an integrative, theory-based framework of IJV success factors. We use this framework to systematically depict the results of both empirical studies related to Sino-foreign IJVs and to IJVs in general. Finally, we draw important implications from the research and propose potential paths for future study.

We address the institutional voids hypothesis, which suggests affiliation with a business group will improve a firm's performance in circumstances of poor-quality institutions and extensive market failures. We hypothesize that initial positive effects of group affiliation should decline as the quality of market institutions improves. Further, we hypothesize that differences in state and private ownership will influence the value and persistence of firm affiliation. Using data on 476 publicly listed firms in 1999 and 467 matched firms in 2004, we find support for a temporal hypothesis that affiliation with a business group improves performance, but the value of group affiliation declines over time. We also find support for a state ‘helping hand’ hypothesis that suggests firms with high levels of state ownership initially experienced an amplified value effect from their group affiliation, which disappeared by 2004. The results suggest that China's policy makers are beginning to establish an institutional and market infrastructure that is conducive to entry by unaffiliated, freestanding firms.

Guanxi, a social network tie drawing on connections in business relations, has been identified as a powerful strategic tool helping organizations maintain competitive advantages and achieve superior performance. However, prior empirical studies on die gM/m-performance link provide indefinite conclusions. The purpose of this study is to systematically review and quandfy the guanxi-performance link in a meta-analytic framework by decomposing guanxi into business ties (i.e., guanxi with business partners) and government ties (i.e., guanxi with government authorities) and organizational performance into economic performance and operational performance. Based on effect sizes from fifty-three studies encompassing 20,212 organizations, we estimate that the overall effect size of the guanxi-pertormance relationship is positive and significant, thus endorsing the argument that guanxi does enhance organizational performance. Specifically, our meta-analysis results demonstrate that both business and government ties lead to both economic and operational performance. However, business ties have a bigger impact on operational performance, whereas government ties exert larger effects on economic performance. Further meta-analytic regression results suggest that ownership (state-owned vs. non-state-owned) and location (Mainland vs. overseas China) explain some of the variations of the guanxi-performance link. Both business and government ties are more important to organizations in Mainland China than to those in overseas China. Government ties are more important to state-owned than to non-state-owned organizations. Lasdy, while business ties remain a valuable strategic tool in China, the importance of government ties is time-variant and has been declining with the development of the institutional environment in China.
