Abstract:Based on a influencing mechanism analysis of network postions and network desity on explorative innovation in R D colloboration networks, a theretical model regarding network prominence, structural holes and network density on explorative innovation is build. This is further tested on sample of 215 firms with joint-filing patents in China from 2007 to 2016 with negative binomial regression. Empirical results reveal that both network prominence and structural holes have inverted U-shaped effects on explorative innovation, and the former position exerts greater influence than the latter one. Network density positively moderates the link between network prominence and explorative innovation and negatively moderates the link between structural holes and explorative innovation. In sparse network, governments can emphasize on breaking path dependence of central actors while strengthening the hub effects of bridging actors. In dense network, governments can highlight enhancing the demonstration effect of central actors while improving information heterogeneity of bridging actors.
