| 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。 |

| The effective policy methods are very important for pollution abatement. Based on the duopoly product quantity competition model, this paper incorporated environment tax, environment regulation, pollutant emission trading into the bench model and built an unified theoretical frame to compare the effectiveness of these three environmental methods in imperfect competition industry. The study found that market mechanism based environmental economic policy is more effective than environment regulation. Besides that, the environment tax is as effective as emission permits trading, the higher the environment tax or permission price is, the less pollutants will be emitted by the industry. These conclusions will be helpful to improve current policy methods for pollution abatement in China, reduce the energy consumption and pollutants emission in some imperfect competition industries like petrochemical, electricity and steel etc. |
