排污权的设定是我国在治理环境污染过程中一项重要的政策。客观地评价这项政策的实施效果,不仅有利于政策本身的实施和完善,同时也可为其他地区开展相关工作提供借鉴。采用2004~2014年中国30个地区的面板数据,借鉴国内外评价政策实施效果的主流计量方法——双重差分法(Difference-in-Difference,DID),建立环境技术进步测度模型,探究排污权设定对环境技术进步的影响,最后提出政策建议。研究发现:当期排污权的设定并未对中国省际环境技术进步产生显著影响,但是在设定2 a之后,排污权在一定程度上控制了污染物的排放,其对我国环境污染的治理具有一定的促进作用,由此可以说明排污权确实能够提高环境技术进步。从长远来看,排污权的设定有利于我国经济健康可持续的发展。
The establishment of emission rights is an important policy in the process of environmental pollution control in our country. To objectively evaluate the implementation effect of this policy will not only be conducive to the implementation and improvement of the policy itself, but also provide reference for other areas to carry out relevant work. Based on the panel data of 30 regions in China from 2004 to 2014, this paper draws lessons from the Difference-in-Difference (DID) method, which is the mainstream measurement method for evaluating the implementation of evaluation policies at home and abroad, establishes a measure model of environmental technology progress and explores emission rights Set the environmental technology progress, the final proposed policy recommendations. The study found that the current emission rights setting did not have a significant impact on the progress of environmental technology in China’s provinces, but after a set period of 2 years, the emission rights control to a certain extent the emission of pollutants and its control on China’s environmental pollution Has a certain role in promoting, which shows that emission rights can indeed improve the environmental technology. In the long run, setting emission rights is conducive to the healthy and sustainable development of our economy.
