专利视角下集成电路企业技术创新合作网络演化分析

[Purpose/ Significance] Strengthening the innovation capability of the IC industry and building a stable net⁃ work of cooperative innovation relationships is an important economic development strategy to promote China’s IC field to break through the technological bottleneck as soon as possible and stand out in the international competition. [Method/ Process] Based on the patent data in the IC field, the inter-enterprise evolutionary network, industry-academia-research evolutionary network, and relationship characteristic evolutionary network was constructed, and the network evolutionary development law in the IC field was explored from the perspective of overall evolutionary trend and network characteristic changes. [Result/ Conclusion] The gap between the head enterprises and other small and medium-sized enterprises is large, and the long-tail effect is more obvious. Universities and research institutions are pioneers in the field and can help enterprises reduce the influ⁃ ence of distance and deepen the trust mechanism. Inter-enterprise network centrality and cohesion have fluctuated in recent years, with a slight decrease in the growth rate of network size and a gradual bias of cooperation towards the trend of techno⁃ logical diversity, geographical proximity, and upstream and downstream development of the industry chain.
