Simulation Research On Anhui Province Carbon Tax Policy Based On CGE Model

Since the 21st century,global warming has brought huge challenges to the world’s ecology.Environmental issues have received extensive attention from the international community.The shortage of traditional fossil energy reserves has prompted the world economy to move towards a low-carbon road.The rapid development since the reform and opening up has benefited from the extensive investment in fossil energy and has also severely damaged the ecological environment.China has been committed to reducing carbon emissions and has made a series of energy conservation and emission reduction commitments at international conferences.In the face of the world’s development of a low-carbon economy and the domestic need to get rid of traditional fossil energy dependence,the collection of carbon taxes is one of the important energy policies for my country to achieve low-carbon economy.Due to differences in energy endowments,economic levels and industrial structures in various regions of our country,the impact of carbon taxes on regions varies.It is necessary to carry out a provincial carbon tax simulation analysis.At present,the domestic research on carbon tax almost stays at the national level impact analysis.There are few studies on the impact of regional carbon taxes,so this article selects Anhui Province for carbon tax analysis.First,it can provide a basis for the formulation of carbon tax policies in Anhui Province,and the second is to enrich the research system of regional carbon tax CGE.The article analyzes the energy status and industrial structure of Anhui Province,splits 42 departments of the input-output table into 21 departments based on the actual situation,and compiles the micro SAM.Constructed an energy CGE model in Anhui Province,analyzed the changes in the ad valorem tax on six types of energy in Anhui Province under the four carbon emission reduction targets,and systematically analyzed the fossil energy and clean energy consumption of various departments in Anhui Province,and the departmental GDP under different carbon taxes.,Sector output,and trends in macroeconomic variables.Research conclusions show that:(1)Carbon tax policy can effectively reduce carbon dioxide emissions in Anhui Province.With the increase in carbon dioxide emission reductions,the ad valorem tax rates for the six energy sources have also increased,among which the ad valorem taxes on raw coal and coke have the highest increase;(2)The higher the carbon tax rate,the more significant the emission reduction effect.It also has a stronger inhibitory effect on regional economic development;(3)The imposition of a carbon tax can transform Anhui’s high-carbon energy consumption structure to low-carbon.Coal use in all industries has gradually declined and the decline is the largest;about 70%of industries are also in a downward trend in oil use,and the decline is smaller than that of coal.As for the use of natural gas,industries that are not highly dependent on coal and oil have increased to varying degrees;(4)Carbon tax policies can affect the transformation of the industrial structure of Anhui Province,and the reduction of carbon emissions will increase the industrial structure.The transformation trend of the three industries will become more obvious.Finally,based on the conclusions obtained,specific suggestions are made on the three aspects of Anhui Province’s industrial structure,energy transformation,and perfecting the carbon tax system.Figure 11 table 20 reference 76...
