Abstract Based on the social network theory and knowledge spillover effect, he panel data of industry-university collaborative patents from 2004 to 2015 is used to combine individual collaboration network with inter-regional collaboration network through the social network analysis and negative binomial regression. The study clarifies the impact of the ego-network dynamics on the overall innovation performance of enterprises and explores the interactive effects of two networks. The results show that the ego-network expansion promotes innovation performance, but the ego-network stability impedes innovation performance. When regions’ centrality, structural holes are high, the negative effects of ego-network stability on collaboration performance are weakened; the negative effects are enhanced when clustering coefficients are high. The structure indexes of inter-regional collaboration network do not have the predicted effects between ego-network expansion and innovation performance.
