【摘要】：各级政府贯彻落实绿色发展的理念,实现经济增长与环境保护的共赢,才能真正实现"绿水青山就是金山银山"。在经济"新常态"背景下,防治环境污染是个复杂而系统性的工程,需要进行经济追因与综合治理,其中,制定实施有效的环境政策工具尤为关键。本文把微观经济学中的双寡头产量竞争模型作为基准模型拓展用于环境经济分析,并把环境税、环境规制、排污权交易这三类主要环境工具对企业生产决策的影响纳入基准模型,旨在对比研究不完全竞争行业中环境工具的有效性问题。结果表明:主要基于市场机制的环境经济政策比行政色彩浓厚的环境规制更有效率。提高环境税率或排污权价格均能显著削减行业污染物排放量,如果环境税率恰好等于排污权价格,则环境税与排污权交易这两类环境工具的效力相等。这对进一步建立和完善我国尚处于探索或初始实施阶段的环境工具,促进石化、电力、钢铁等不完全竞争行业的主要污染物减排,具有一定参考价值和借鉴意义。
[Abstract]:Only when governments at all levels implement the concept of green development and achieve win-win results in economic growth and environmental protection can "green water and green mountains be called Jinshan Yinshan".Under the background of "new normal" of economy, prevention and control of environmental pollution is a complex and systematic project, which needs to carry out economic recovery and comprehensive management. Among them, it is very important to formulate effective environmental policy tools.In this paper, the duopoly model of production competition in microeconomics is used as the benchmark model for environmental economic analysis, and environmental tax, environmental regulation,The impact of three kinds of environmental tools, emissions trading, on enterprise production decision is incorporated into the benchmark model, which aims to compare and study the effectiveness of environmental tools in incomplete competition industries.The results show that the environmental economic policy based on the market mechanism is more efficient than the environmental regulation with strong administrative color.If the environmental tax rate is exactly equal to the emission price, then the environmental tax and emission trading are two kinds of environmental instruments.It is of certain reference value and significance to further establish and perfect the environmental tools which are still in the stage of exploration or initial implementation in our country and to promote the emission reduction of major pollutants in the incomplete competition industries such as petrochemical, electric power, iron and steel, etc.
