Research on the Key Provincial Carbon Emission Reduction Sectors at the Production Side and Consumption Side in China
Under the background of"carbon peak"and"carbon neutral",carbon emissions in industrial linkages have become a current research hotspot.By screening key carbon reduction sectors in China at the provincial level and implement-ing corresponding industrial structure adjustment and optimization policies,the goal of carbon reduction can be accurately and efficiently achieved.This study is based on the multiple region input-output model in China,and uses the input-output meth-od to construct an economic and carbon emission correlation model between provincial-level industries,and then analyzes the industrial sectors with significant carbon emission linkage nationwide.By using the method of industry correlation analysis,the changing trends of the influence coefficient and sensitivity coefficient between industrial sector economy and carbon emissions were explored,and key provincial-level carbon reduction departments in China were identified from the production and consumption sides,respectively.The main conclusions of this study indicated that at the national level,there are differenc-es in the sectors with significant carbon emission correlations from different perspectives of backward and forward linkages.Specifically,on the supply side,the production and supply industries of electricity and heat are the sectors with the highest carbon emission correlation.On the consumption side,the construction industry is the sector with the highest carbon emission linkages.During the period 2010-2017,the production and supply industries of electricity and heat,as production side sectors,promoted the improvement of national carbon emission capacity and scale through backward linkage,but their contribution to the growth of national economic scale was relatively limited.The construction industry,as a consumer sector,has a significant impact on driving national carbon emissions through forward linkage rather than promoting the economy.At the provincial level,the key emission reduction sectors on the production side are mainly concentrated in the production and distribution of electric power and heat power in Hebei,Shanxi,Inner Mongolia,and the transportation and warehousing industry in Xinjiang.The key emission reduction sectors on the consumption side are mainly concentrated in the manufacture of non-metallic mineral products in Hebei,Inner Mongolia,Zhejiang,Jiangxi,Guangxi,Chongqing,Sichuan,Yunnan and Shaanxi,as well as the smelting and rolling processing of metals in Yunnan,and the transportation and warehousing industry in Xinjiang and Yunnan.Finally,this study proposes corresponding suggestions for different types of key carbon reduction provincial sectors in China based on the supply and consumption ends of the industrial chain.
