Research On Industrial Transfer And Its Environmental Effect In Yangtze River Economic Belt Based On Input-Output Method

Regional coordinated development has become an important development idea for China’s economic development and industrial restructuring.The Yangtze River Economic Belt,Beijing-Tianjin-Hebei Coordinated Development,and the One Belt One Road Regional Development Strategy have comprehensively promoted the pace of regional coordinated development in China.Among them,the Yangtze River Economic Belt spans the developed and underdeveloped provinces of East,West,and Middle China.The gradients of industries in the upper,middle,and lower reaches of the province are obvious,and the advantages of rational use of location can better drive the development and optimization of regional industries.However,at the same time,industrial transfer will inevitably lead to the transfer of pollutants.Therefore,this study will focus on the industrial transfer and environmental benefits of the Yangtze River Economic Belt,and hopes to analyze the pattern of industrial transfer and pollutant transfer in the economic belt.Make meaningful suggestions for the model of economic transfer of regional industries.This paper mainly uses the inter-regional input-output method to quantitatively calculate the transfer of industries and pollutants caused by consumption,investment,and exports,and analyzes the direction and path of the transfer of industries and pollutants.The results show that the general route for the transfer of internal industries and pollution emissions is transferred from the downstream areas to the upstream areas,and the middle reaches of the area are transfer areas.With regard to industrial transfer and pollutant transfer in external provinces and cities,the combined effect of consumption,investment,and exports is that the economic zone is a net transfer area for sulfur dioxide and greenhouse gas emissions,and it is also a net transfer area for chemical oxygen demand.Sulfur dioxide(SO2)and carbon dioxide(CO2)emission transfer mainly from electricity,thermal production and supply industries,metal smelting and calendering processing industries,chemical oxygen demand(COD)emissions transfer mainly from food manufacturing and tobacco processing industry,paper printing and education and sports supplies manufacturing and chemical industry.Finally,based on the conclusions,several suggestions are made for industrial development and reduction of pollutants emission in the economic zone.
