Impact of Industrial Co-Agglomeration on Green Economic Efficiency
As the trend of industrial development,the co-agglomeration of manufacturing and producer services is an important way to achieve green and high-quality development.By selecting panel data from 285 cities in China and using panel threshold model,this paper focuses on the non-linear relationship between the co-agglomeration of manufacturing and producer services on green economic efficiency and its industrial and regional heterogeneity.The research shows that when taking the co-agglomeration of manufacturing and producer services,city size and environ-mental regulation as threshold variables,there is a single threshold for the impact of the co-agglomeration of manu-facturing and high-end producer services and general producer services on the green economic efficiency,showing an inverted U-shaped relationship.When taking the level of economic development as the threshold variable,there is dual threshold for the impact of the co-agglomeration of manufacturing and high-end producer services and general producer services on the green economic efficiency,showing an inverted U-shaped relationship,and the co-ag-glomeration of manufacturing and high-end producer services has a greater impact on the efficiency of green econo-my.Therefore,we should promote industrial co-agglomeration according to local conditions,give full play to the ad-vantages of the market and government,and scientifically plan the distribution of industries and supervision intensity.
