Abstract: The key breakthrough of promoting the effect of industrial technology innovation lies in defining the path of technological innovation. Based on integrated circuit related technology patents, analyze the structural characteristics of industrial cooperative innovation networks, and outline typical cooperative innovation paths; explore the formation process and influencing factors of integrated circuit technology cooperative innovation networks, use complex networks to build knowledge innovation network evolution models, and analyze through simulation analysis, the paper further analyzes the change of innovation performance and the evolution of network structure. The results show that the knowledge innovation ability has a significant positive effect on the performance of cooperative innovation, and the adoption of multi-type technology innovation strategy is beneficial to the development of the innovation subject when the technological differences among the participants are large, when the technological differences among the participants are small, the centralized technological innovation strategy is appropriate. The degree of dependence on technology path will influence the choice of partner strategy, and the degree of dependence beyond a certain threshold will seriously inhibit the improvement of innovation performance, and the inhibition effect can be weakened to some extent by improving the innovation ability of the innovation subject. On the basis of model simulation analysis, three optimization paths for technological innovation in China's integrated circuit industry are proposed, namely "innovative network edge nodes seek 'aggregation nodes'", "technological innovation-oriented node extension cooperation" and "market revenue-oriented node strengthening" internal connections".
