[Purpose/Significance] The purpose is to study the evolution characteristics of technological innovation cooperation network in the field of tumor vaccines, and to provide ideas for technological breakthrough and industrial development in the field of tumor vaccines in China. [Method/Process] This paper presented a method and framework for analyzing the evolution characteristics of industrial technological innovation cooperation network. Firstly, the patent index method was introduced to divide the technology life cycle of tumor vaccine industry through the quantitative calculation of technology growth rate, technology maturity coefficient, technology aging coefficient and new technology characteristic coefficient; Secondly, the social network analysis method was used to construct the cooperative network at each stage of the technology life cycle, and the topology evolution law of the cooperative network was analyzed from the dimensions of node number, network density, central potential and core-edge analysis; This paper analyzed the evolution law of core individuals from the dimensions of centrality, cohesive subgroup analysis and innovation institutions, and then revealed the dynamic evolution characteristics of technological innovation cooperation network in tumor vaccine industry. [Result/Conclusion] Taking the tumor vaccine strategic emerging industry as a case study, the effectiveness and feasibility of the method are verified, which provides a theoretical basis for technology development strategy and technical cooperation in the field of tumor vaccine.
