Abstract:On the basis of clarifying the function mechanism of co-agglomeration of high-tech industries and producer services on regional innovation efficiency, through comparative analysis and empirical research, the results show that: the level of co-agglomeration of industries in China presents the evolution trend of steady improvement and the regional difference between east and west; The innovation efficiency of China's technology research and development stage is higher than that of the economic transformation stage. The Yangtze river delta and the Pearl river delta have stronger technology research and development capabilities. Beijing and Tianjin have more comparative advantages in the stage of economic transformation. Heterogeneous industries act on regional innovation efficiency through innovation factor coupling, technology ripple and spillover effect, and can effectively solve the decoupling problem of innovation process. The Yangtze river delta region can achieve the improvement of innovation efficiency through industrial co-agglomeration, while the Beijing-Tianjin-Hebei region has no significant influence on the improvement of innovation efficiency.
