Study On The Measurement And Influencing Factors Of The Industrial Green Development Level Of The Yangtze River Delta Urban Agglomeration

Since the reform and opening up,China’s industrial economy has developed rapidly with remarkable achievements,but the industrial development model is still relatively extensive,resulting in resource depletion,environmental damage and other problems.Therefore,the 18 th National Congress of the Communist Party of China clearly proposed the development mode of green development.The Yangtze River Delta region is an economically developed region in China,with outstanding industrial development and advanced modernization transformation.This article selects 26 cities in the Yangtze River Delta urban agglomeration,and comprehensively uses entropy weight method,TOPSIS evaluation method,spatial variation function,Kriging difference,standard deviation ellipse and center of gravity analysis,as well as geographic detector model to calculate the industrial green development level of 26 cities in the Yangtze River Delta from 2011 to2020.It analyzes the spatiotemporal evolution characteristics,explores influencing factors,and proposes reasonable suggestions.The main content includes:(1)Evaluation of the Industrial Green Development Level of the Yangtze River Delta Urban Agglomeration.Based on relevant theories such as green development and industrial green development,drawing on existing research,constructing an evaluation index system and calculating weights,analyzing the level of industrial green development in each city from 2011 to 2020.The results show that the overall trend shows a stable increase,but there is a significant gap between cities.(2)Analysis of the spatiotemporal evolution of industrial green development in the Yangtze River Delta urban agglomeration.Exploring the spatial correlation of urban agglomerations from 2011 to 2020 through spatial variation functions,Kriging difference models,and standard deviation ellipse models.The results show that the spatial differences in industrial green development from 2011 to 2020 have gradually expanded,with the random components in the spatial differences continuously decreasing,structural differences highlighting,and significant characteristics of center of gravity movement.(3)Analysis of the influencing factors of industrial green development in the Yangtze River Delta urban agglomeration.Select 23 influencing factors and analyze the differences in industrial green development through geographic detector models,and analyze the interannual change trends in 2011,2014,2017,and 2020.The results show that in a single factor,the impact intensity of industrial ecological economy and ecological environment increases,while the impact of education and technology decreases;In the dual factor interaction detection,all factors have achieved enhanced influence through interaction,and different combinations of dual factor interactions have stronger explanatory power,while the number of dual factor enhanced types decreases.(4)Suggestions for Green Industrial Development in the Yangtze River Delta Urban Agglomeration.Based on the analysis of the differences and influencing factors of industrial green development in the Yangtze River Delta,it is proposed to establish a sound legal,regulatory,and policy system for industrial green development,promote ecological environment protection,actively optimize the urban industrial green structure,and strengthen industrial green technology innovation.
