Spatial-Temporal Evolution and Influencing Factors of Industrial Green Innovation Efficiency in the Yangtze River Economic Zone
Abstract
Based on provincial panel data of 11 provinces of Yangtze River Economic Zone in 2011-2018 years,this paper uses the Super- SBM method to analyze the industrial green innovation efficiency of Yangtze River Economic Zone,At the same time , on the basis of the spatial-temporal evolution analysis of industrial green innovation efficiency , we use the spatial econometric model to make an empirical study about the influencing factors of industrial green innovation efficiency .The results show that the industrial green innovation efficiency of the Yangtze River Economic Zone has not reached the DEA effective state, and there is some room for improvement.Regionally, the downstream is the highest,the upstream is the second , the middle is the lowest;There are great differences of the industrial green innovation efficiency in different provinces, Shanghai, Zhejiang, Anhui, Chongqing, Hunan and Sichuan are more ideal, while other provinces are not. The results of spatial-temporal evolution show that, the efficiency of industrial green innovation in the Yangtze River economic belt shows the spatial distribution characteristics of "high at both ends and low in the middle ",The results of the spatial economic model show that,in addition to the influence of energy consumption structure is not significant, enterprise scale, industrial structure, financial development, degree of marketization and environmental regulation can significantly promote industrial green innovation efficiency, while economic growth has obvious inhibitory effect.
