摘要
如何减少经济增长中的污染排放是中国新时期面临的重要任务。就区域角度来说,理论上存在技术引致的降低污染和排污产业转移的降低污染,后者尤其需要引起警示。同时,实现中国区域协调发展中,城市群的作用日渐突出,以城市群扩容的区域一体化合作方式成为区域经济协调发展的重要政策工具。尽管已有研究表明城市群扩容的区域一体化显著促进了城市经济共同增长,但在环境治理层面上,是否也会带来污染转移而影响不同地区的经济高质量发展,还缺乏有效的实证研究。本文以长三角城市群扩容的"准自然实验"为考察对象,首先通过理论模型提出政府之间推进区域一体化合作导致污染转移的理论机理,随后采用2003-2015年中国地级以上城市数据,通过双重差分(DID)方法对扩容带来的污染排放变化进行了实证检验。研究发现,通过城市群扩容的区域一体化具有显著的减排效应:从总量上看,污染排放通过原位城市向外围新加入城市转移,显著降低原位城市排污水平的同时,新加入城市的污染排放增加了;从结构上看,在降低原位城市污染密集度的同时并未增加新加入城市的排污密度,因而有利于新加入城市的经济规模总量上升;从整体上看,区域一体化合作显著带动了城市群的减排效应,有利于提高城市群经济发展的整体质量。本文研究结论的重要意义在于:通过地方政府一体化合作推动中国区域经济协调发展过程中,不仅要关注经济层面的合作,更要强调污染排放的协同治理与绿色发展合作,从而实现经济与环境的双赢效果。
It is an important task faced by China that how to reduce pollution emissions in economic growth in the new era.From a regional perspective,there are two ways to reduce pollution emissions which can be called technology-induced pollution reduction and transfer the polluting industry out.The latter in particular needs to be alerted.At the same time,the role of urban cluster has become increasingly prominent under the background of promoting regional coordinated development in China,and the enlargement of urban cluster with aims of regional integration and cooperation of local government has become an important policy tool in China’s regional development.Although studies have shown that the regional integration of urban cluster significantly promotes the common growth of urban economy.However,from an environmental perspective,whether regional integration will also bring about pollution transfer and therefore affect the development quality of different regions remains a question.This paper took the‘quasi-natural experiment’of the enlargement of the Yangtze River Delta urban cluster as the object of investigation.Firstly,the theoretical model was proposed to promote the theoretical mechanism of pollution transfer caused by regional integration cooperation between the governments.Then,the data of 286 cities in China from 2003 to 2015 was adopted.The differenc E-in-difference(DID)method was used to empirically test the pollution emission change caused by the enlargement.The study found that regional integration through enlargement of urban cluster had significant emission reduction effects:From the total amount,pollution emissions were transferred from incumbent cities to new cluster cities and as a result,pollution emission significantly reduced in incumbent cities while it increased in new cluster cities.From the structural point of view,the pollution intensity of incumbent cities reduced without increasing the pollution intensity of new cluster cities.Overall,regional integration had significantly driven the e
