Accelerating the synergy of pollution reduction and carbon reduction is a fundamental requirement for im-plementing the construction of ecological civilization in the new development stage,and it is an important tool for pro-moting the synergy of environmental protection and economic development,improving the efficiency of resource utili-zation,and promoting economic transformation and upgrading.This paper constructs a closed economy general equi-librium model with five sectors to simulate the dynamic effects of China's macroeconomic and ecological environment quality on the shocks of production technology,policy intensity,and emission reduction innovation technology under three different environmental policy scenarios:total control,carbon tax,and target intensity,and constructs a social welfare function to compare the differences in the welfare loss of Chinese residents under different shocks of the poli-cy of pollution reduction and carbon reduction.The results of the study show that:increasing the appropriate intensity of environmental policies in China can achieve synergistic efficiency,which is manifested in economic growth,declin-ing air pollutants and decreasing carbon stocks,and the"carbon reduction"effect is better than the"pollution reduc-tion"effect.The effect of"carbon reduction"is better than the effect of"pollution reduction".Under the aggregate control scenario,economic output responds better to exogenous shocks,and the synergistic effect of pollution reduc-tion and carbon reduction is more significant under the carbon tax policy scenario.In the aggregate control scenario,final goods production technology shocks have a structural effect on the energy consumption market,while the struc-tural effect is not obvious in the carbon tax and target intensity policy scenarios.The social welfare function examines the level of social welfare of residents under the three policy scenarios,and the social welfare of the three policy sce-narios,in descending order,is as follows:total control,target intensity,and carbon tax policy.Based on the conclu-sions of the study,this paper suggests that the existing environmental governance system should be changed from"di-vide and rule"to"combine and rule",and the environmental governance policy should be changed from"hard con-straints"to"soft incentives",and the environmental governance policy should be changed from"hard constraints"to"soft incentives".Environmental governance policies should be changed from"hard constraints"to"soft incentives",and environmental governance means should be changed from"end-of-pipe"to"source control".
