发布时间：2018-07-13 19:19

【摘要】：本文通过构建包含环保政策因素的三部门动态随机一般均衡(DSGE)模型,研究环保政策、政府治污支出及环境消费偏好等措施对宏观经济的动态效应,尤其是对实际碳排放量和生态环境质量的影响,并在此基础上分析各项措施的传导机制。研究发现:(1)环保技术改善能够在保持经济增长的基础上,显著降低碳排放,提高环境质量;(2)征收碳税以及提升环境消费偏好均能够显著改善环境质量,但对经济增长存在一定的负效应;(3)政府治污支出能够显著降低碳排放量和提高环境质量,但中长期内会对宏观经济产生负效应,通过调整政府治污支出转化系数,能够显著提高政府治污支出措施的有效性。总体上,环保技术与治污支出是保持经济增长与环境质量协调发展的关键,提升厂商的环保技术研发水平与加大治污力度应是现阶段政策制定的参考重点。
[Abstract]:By constructing a dynamic stochastic general equilibrium (DSGE) model with environmental policy factors, this paper studies the dynamic effects of environmental protection policies, government pollution control expenditure and environmental consumption preference on the macro economy. In particular, the effect on actual carbon emissions and ecological environmental quality is analyzed, and the transmission mechanism of various measures is analyzed. The results show that: (1) environmental technology can significantly reduce carbon emissions and improve environmental quality on the basis of maintaining economic growth; (2) levying carbon tax and increasing environmental consumption preference can significantly improve environmental quality. But there are some negative effects on economic growth: (3) the government pollution control expenditure can significantly reduce carbon emissions and improve environmental quality, but in the medium and long term will have a negative effect on the macroeconomic, by adjusting the conversion coefficient of government pollution expenditure, It can significantly improve the effectiveness of the government's pollution control spending measures. In general, environmental protection technology and pollution control expenditure are the key to maintain the coordinated development of economic growth and environmental quality. Therefore, to improve the R & D level of environmental protection technology and to strengthen pollution control should be the key point of policy formulation at the present stage.
