The level of nitrogen oxide tax rate has an important impact on the production enthusiasm of related industries and the results of ecological environmental protection.However,the self-repair and purification ability of the atmosphere can reduce the pressure of emission reduction and tax burden of enterprises.Therefore,the purpose of this study is to quantify the atmospheric self-cleaning capacity and construct a CGE model of relevant dynamic tax rate optimization,so as to simulate and optimize the nitrogen oxide tax rate setting under different atmospheric self-cleaning capacity scenarios.According to the research,on the premise of making full use of atmospheric self-purification capacity,the optimization results of nitrogen oxide tax rate in Inner Mongolia are as follows:8.36 yuan/pollution equivalent in 2021,7.691 2 yuan/pollution equivalent in 2022 to 2025,and 7.383 6 yuan/pollution equivalent in 2026 to 2030.In addition,tax rate optimization has a great impact on exports,but at the same time can increase investment,and the comprehensive impact on GDP is not big.Therefore,the nitrogen oxide tax rate in Inner Mongolia should be raised appropriately,and a dynamic tax rate regulation mechanism should be established.
