PurposePrevious studies examined the effect of inter-organizational collaboration relationships on organizational innovation. However, most focused on the configuration of the network from the static network perspective, and few examined the influence of network structure stability on an organization's exploratory innovation from the ego-network perspective. This study addresses this research gap by focusing on ego-network stability and its effect on an organization's exploratory innovation.Design/methodology/approachThe empirical setting is the smartphone collaboration network from 2004 to 2017. We selected one-site schemes and panel data of patents from the Derwent Innovation Database. A negative binomial model with fixed effects was used to test our hypotheses.FindingsThe regression results show that an organization's ego-network stability has an inverted-U-shaped relationship with its exploratory innovation. Global cohesion of the focal organization's knowledge network moderates the process in such a way that when it is at a high level, an organization's exploratory innovation can benefit more from a moderate level of ego-network stability. However, local cohesion moderates in such a way that, at a low level, an organization's exploratory innovation can benefit more from a moderate level of ego-network stability.Originality/valueThis study highlights the importance of ego-network stability and its effect on the focal organization's exploratory innovation. It contributes to the literature on the relationship between ego-network stability and exploratory innovation by investigating the moderating role of global cohesion and local cohesion in knowledge networks.

PurposeThe purpose of this paper is to explore that relational capability plays a mediator role in the relationship between focal enterprises' control on knowledge transfer risks in R&D network.Design/methodology/approachThe paper reviews the related literature from which it proposes a theoretical hypothesis and conceptual framework which is tested empirically adopting regression methodology by mathematical statistics software.FindingsThe results reveal that focal enterprises' control (core technological capability and network position) have a positive effect on knowledge transfer risks without the mediation of relational capability. Moreover, relational capability mediates the positive relationship between core technological capability and knowledge transfer risks.Research limitations/implicationsThe cross-sectional data of this research has difficult in testing causality between the variables, and future research should take account of the potential factors that can impact on knowledge transfer risks.Practical implicationsThe results provide more valuable information to managers in alleviating knowledge transfer risks in R&D networks. For one thing, the study indicates how focal firms' control (core technological capability and network position) can be taken advantage of improving R&D efficiency and reducing the knowledge transfer risks. For another, the results emphasize that relational capability plays an important role in interacting with cooperative enterprises in the process of R&D activities.Originality/valueFew studies present a theoretical discussion on focal firms control as the important determinants of knowledge transfer risks especially in the R&D network. Moreover it expands the related risk management theory by relational capability that mediates the relationship between focal firms control and knowledge transfer risks.

Purpose This paper aims to propose the following questions: How does dynamic positioning influence organization’s innovation performance? Does knowledge base mediate the relationship between them? Design/methodology/approach The empirical setting of this study is the smartphone collaboration network from 2004 to 2017; the authors selected one-site schemes and data of patents from the Derwent Innovation Database. Furthermore, the authors adopted the negative binomial model with random effects to test the hypotheses. Findings The regression results show that organization’s dynamic positioning has an inverted-U-shaped relationship with its exploratory innovation. Similarly, organization’s dynamic positioning has an inverted-U-shaped relationship with its exploitative innovation. Besides, knowledge base mediates the relationship between dynamic positioning and organization’s innovation performance. Originality/value This study empirically confirms the relationship between dynamic positioning and organization’s innovation performance by separately examining exploratory and exploitative innovation. Furthermore, this study provides a contribution to the literature linking dynamic positioning and organization’s innovation performance by investigating the mediating role of knowledge base.
