环境公共治理政策的效果评价与优化组合研究

Research on the Effects Evaluation and Optimization of Environmental Public Regulation Policy

本文构建了包含环境治理体系的动态一般均衡模型,基于模型的研究发现,在经济增长方面生产者补贴较为有效;而技术研发补贴在技术进步中的作用十分显著,其通过"研发投入→绿色技术提升→降低污染物排放"的路径可以实现环境质量的改善。此外,本文还模拟了生产者补贴和技术研发补贴的政策组合对社会福利和污染排放的影响,结果显示,政府可以采用生产者价格补贴或技术研发补贴促进产出水平增长进而提高社会福利水平,同时增大生产者价格补贴和技术研发补贴的幅度则能够通过提高技术水平促使污染水平不断下降。最后,本文给出了社会福利增进与环境质量改善双重目标下生产补贴和技术研发补贴政策的可行性区域,进行了环境公共治理政策的优化组合研究。

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.
