Abstract In this paper, we analyze the effect of structure holes from the perspective of dynamics, exploring the relationship between the various evolution forms and evolution results of structural holes, which is different from the traditional "static structureperformance" paradigm. We aim at providing some effective advice for individuals and organizations when they integrate the network resources to innovate. The samples of the study cover all the invention and utility model patents from 41 hightech sectors in China electronic information and the automotive industry. Based on these 36338 patents data, we build the dynamical collaborative network at the team level. Using negative binomial regression model, we analyze the effect of collaborative networks on enterprises' innovation capacity. The empirical results show that: the number of structural holes that generate and are closed as well as their ratio significantly and positively influence the innovation capability of hightech sectors. Considering time effect, we further get the following conclusions: the number of structural holes generate and closed positively and significantly influence the innovation ability of enterprises, but the effect of the latter weakens over time; like the former, the effect of their ratio can persist within a long period.
