科创企业合作创新网络的合作模式、演化特征及行业异质性分析OACHSSCD

To explore the collaborative innovation models and network evolution patterns of science and technology innovation enterprises,this study selected companies listed on the Sci-Tech Innovation Board(STAR Market)as the research subject.Utilizing joint patent application data from 2001 to 2023,we constructed enterprise collaborative innovation networks using social network analysis(SNA).A systematic analysis was conducted on the model characteristics,evolutionary patterns,and industry heterogeneity of this network.The findings reveal that:collaborative innovation has become a critical pathway for science and technology enterprises to break through technological barriers,howev-er,the distribution of collaborative innovation models is highly uneven,with most enterprises exhibiting resource-scarce cooperation or internal-oriented models,a deeply integrated industry-university-research ecosystem has yet to be formed;From 2001 to 2023,the evolution of the collaborative innovation net-work progressed through three distinct stages.Over time,the network generally transitioned from a small-world structure towards a scale-free structure,with technology innovation enterprises gradually e-volving into the dominant force within the collaborative network;Significant industry heterogeneity ex-ists.Collaborative innovation networks across different sectors on the STAR Market exhibit distinct in-dustry-specific characteristics.Further innovation and development of technology innovation enterprises necessitate industry-targeted and precision-tailored strategies.
