Research on Characteristics and Dynamic Mechanism of Green Technology Innovation Network Based on TERGM

Based on the micro-green patent cooperation data of high-end equipment manufacturing enterprises from 2010 to 2022, the enterprise association is raised to the city association, and the green technology innovation city net-work is constructed. Social network analysis (SNA) and time index random graph model (TERGM) are used to explore and analyze the dynamic evolution characteristics of the green technology innovation network structure and the dynamic mechanism of endogenous and exogenous factors. The results show that the green technology innovation network as a whole presents a "core-edge" development trend, the network development is becoming more and more complex, and the characteristics of "small world" are extremely obvious; There are significant differences in green innovation among cities. Beijing has become the core node of the fault, and cities such as Shanghai, Shenzhen and Guangzhou tend to form regional link networks; The green technology innovation network has structure-dependent effect and time-dependent effect; Cities with better economic foundation, green innovation capabilities, and green financial development have a greater probability of establishing green technology innovation network links with other cities; Proximity plays a positive role in the expansion and linking of green technology innovation networks. The research conclusion provides a path reference for the follow-up coordinated development of green technology innovation, and provides a new research perspective for promoting the research of social green transformation and development.
