Study On The Effect Of Regional Carbon Emission Transfer In China Under The Policy Of Different Carbon Tax

Since the reform and opening up,China’s economic growth mode is mainly resource-intensive,while the traditional extensive economic growth mode is at the cost of environment and resources.The high carbon emission problem makes China’s economic development face potential threats.In the face of severe climate problems,it has become one of China’s development goals to change the extensive economic development mode and develop low-carbon economy to promote sustainable development.Since January 2018,carbon tax policy has been officially issued,and each province(district and city)has issued the specific applicable tax for local taxable air pollutants.Due to the vast territory of China,the economic development level and industrial structure of different regions are greatly different,and the regional economic development is extremely unbalanced.Different tax rates may cause the transfer of polluting industries to low-tax areas,resulting in the "pollution transfer" phenomenon of local carbon emission reduction and the increase of carbon emissions in low-tax areas.The development of low-carbon economy needs to implement the principle of regional pooling,which requires in-depth analysis of China’s regional carbon emission transfer.In 2012 the country 30 provinces(municipalities)between the input and output table,on the basis of the country into the beijing-tianjin region,northeast region,north coast,east coast,southern coastal,eastern coastal,central region,northwest region,southwest region of the eight areas,formulation contains the first eight regional social accounting matrix,and in the original modules,increased carbon emissions and environmental module,the introduction of energy inputs in the production module,establish contains eight areas of the country’s energy-economy-environment computable general equilibrium model,a comprehensive interpretation of the carbon tax rate,a series of influence on the regional analysis in an environmental tax rate,Our country each big area energy usage,regional output,carbon emissions,carbon emissions intensity change,and in the region of the carbon tax policy under the eight transfer flow and transfer between carbon intensity,and analyze the highly polluting enterprises will shift to a low tax area,resulting in partial carbon emissions and the phenomenon of regional carbon emissions increase of lower taxes.The research conclusions obtained in this paper are as follows :(1)from the perspective of the national total carbon emissions,the emission reduction effect brought by the differential carbon tax policy is not ideal,and the national total carbon emissions are not significantly reduced,or even slightly increased.(2)from the perspective of a single region,carbon tax policies have different impacts on different regions.Beijing and tianjin,the eastern coastal region,the northeast region and the southern coastal region show emission reduction effects,and carbon emissions have been reduced,and there are also spatial differences in emission reductions.However,carbon emissions increased in the central region,northwest region,southern coastal region and southwest region,especially in the central region and northwest region,and the implementation of differential carbon tax policy only caused local carbon emission reduction.(3)there is a phenomenon of pollution transfer between regions in China.Beijing and tianjin regions with high carbon tax rates and the economically developed eastern coastal areas are where carbon emissions are transferred,while the northwest and central regions with low carbon tax rates are where carbon emissions are transferred.(4)China’s carbon emission transfer path,on the whole,from the southeast coast to the northwest region,from the high tax rate region to the low tax rate region.
