Evolutionary Mechanisms of Technology Innovation of Strategic Emerging Industries in China at the Prefecture Level
Based on the data of invention patent applications in 282 China's prefecture-level cities from 2010 to 2021,and using the theory of evolutionary economic geography and the biological evolution's metaphor of Generalized Darwinism,this paper constructs a theoretical analysis framework of technology innovation of strategic emerging industries from three dimensions of technological relatedness,diversity and complexity,and explores the impact of the urban knowledge base,technological structure and technology market on the technology innovation development of strategic emerging industries.It's found that:1)The patent output of strategic emerging industries in China is large in scale and fast in growth,and shows the gradually weakening distribution pattern from the east of China to the west of China.2)The overall levels of technological relatedness and diversity have risen significantly in prefecture-level cities,and the technological space shows the characteristics of"core-edge"and"dual-core"structure.3)The innovation of industrial technology is influenced by a combination of technological relatedness,diversity and complexity,technological relatedness is conducive to technological entry and development,while technological diversity is not conducive to technological entry and development,technological complexity hinders the technological entry but facilitates technological development.It explores the developmental and evolutionary mechanisms of technological innovation of strategic emerging industries from the perspective of endogenous development of industrial technology,which enriches empirical research on the development of new quality productive forces in China,expands the analytical perspective of industrial technology evolution,and deepens the understanding of the laws of industrial technology innovation and development.
