Research on the Impact of Regional Innovation Cooperation Network on Technological Innovation Performance: Based on the Yangtze River Delta

[Purpose/Significance] Based on the moderating effect of regional innovation cooperation network's clustering coefficient and average shortest path length, the paper analyzes the impact of enterprise centrality in network on technological innovation performance, in order to provide reference to enterprise innovation management. [Method/Process] Using patent data to construct patent cooperation networks, this paper builds a theoretical model measuring technological innovation performance of an enterprise, with degree centrality and betweenness centrality of the enterprise in the network as independent variables, with the clustering coefficient and average shortest path length of patent cooperation network as a moderator variable. [Results/Conclusions] The empirical study in the field of integrated circuit technology in the Yangtze River Delta is carried out and the stepwise multiple linear regression results show the following conclusions. The density of cooperation network, the accumulation of technological i
