Abstract: In this paper, we specified a dynamic general equilibrium model which including the environmental regulation policy system. We can obtain the conclusion that the impact of producer subsidies is relatively effective in the aspect of economic growth. The role of R&D subsidy in technological progress is very significant. Through the way that “R&D investment?Green technology promotion?Discharge of pollutants reduction”, the environmental quality can be improved. Additionally, in this paper, we also simulate the impacts of producer price subsidies and technical R&D subsidies on the social welfare and pollution discharge respectively. The results show that the government may promote the production level and thus the social welfare level by the ways of producer subsidies or R&D subsidies. Increasing the magnitude of the producer price subsidies and R&D subsidies simultaneously has positive effects on the technology progress which is helpful to the pollution level declining. In the end, this paper presents the feasible region of production subsidies and R&D subsidies under the dual objectives of social welfare and environmental improvement and does some research on the optimal combination of environmental public governance policies.
