摘要

The paper builds a dynamic computable general equilibrium model (Dynamic CGE Model) to evaluate the impact on carbon emissions reduction and haze with different scenarios of coal resource tax rate adjustment. The results shows that: Overall speaking, coal resource tax reform can be conducive to promote CO2 emission reduction and environmental benefits from a longer time rang, but the impacts are different with the three kinds of policy design which are 2%,5% and 10% respectively. Increased coal resources tax inhibits resources consumption, improves resource utilization efficiency, and reduces haze emission; meanwhile, the implementation of resource value compensation policy plays a more positive role in improving the environment quality. Compared with the impact by 2% and 10% tax rate, 5% Ad valorem tax should be a reasonable and effective choice for decreasing CO2 emission and PM2.5&PM10, and improving environment welfare. Therefore, some suggestions are given as following: 1) it is necessary to choose coal resource tax rate properly and scientifically. 2) Integrating the policy of resource compensation into the category of resource tax, and further clarify the form of resource compensation standards. 3) Paying more attention to the coordination of resources policy; 4) important mineral resources, forest resources should be incorporated into the resource tax policy.
