排污权的设定对环境技术进步的影响

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。

CAN THE GENERATION OF EMISSION PERMITS LEAD TO #br# ENVIRONMENTAL TECHNOLOGY PROGRESS?

Since the reform and opening-up,China has made remarkable achievements in economic development.However,the rapid economic growth resulted in the environmental destruction to a certain degree.Thus,the government has taken some corresponding measures in order to change this situation.Then the emission permits gradually aroused people's attention,and has consequently grown in prominence as an important policy for environmental pollution control.The proper evaluation of its implementation effect is not only conducive to the policy implementation itself,but also instructive to the development of similar policies in other regions.Based on the panel data of 30 regions in China between 2004 and 2014,this paper established the measurement model of environmental technology progress,and discussed the effects of emission permits by employing the most internationally popular method (namely,Difference-in-Difference,DID) which can quantitatively evaluate policy implementation.In this study,we found that the generation of emission permits did not bring about a dramatical enhancement on China's provincial environmental technology progress immediately.Nevertheless,after 2 years,the implementation of emission permits did limit the pollution emission to a certain extent and presented a positive affect on pollution control.Thus,we can conclude that the establishment of emission permits can actually improve environmental technology progress and is conducive to the healthy and sustainable development of China's economy in the long run.In addition,policy recommendations were made at the end of this paper.
