摘要:

大气污染具有流动性,跨区域特征明显,协同治理至关重要。基于2010-2015年275个城市的面板数据,运用三重差分法(DDD)研究了大气污染协同治理对污染物减排的影响。从全样本分析结果来看,大气污染协同治理降低了工业二氧化硫排放量和工业烟(粉)尘排放量,而此结果并没有通过显著性检验。从子样本分析结果来看,大气污染协同治理显著降低了工业二氧化硫排放量,但对工业烟(粉)尘排放量没有产生显著影响。城市在促进不同污染物减排时存在差异,减排难度较低的污染物往往被优先完成。从时间效应来看,大气污染协同治理对污染物减排的影响存在时滞性,而且这种时滞性在不同污染物减排之间存在差异。

Abstract:

Air pollution has fluidity, with obvious cross-regional characteristics. Therefore, cooperative governance for air pollution is very important. Based on the panel data of 275 cities in mainland China from 2010-2015, this paper uses Difference-in-Difference-in-Difference (DDD) method to explore the effect of air pollution collaborative governance on the reduction of pollutant emission. The results of the whole sample analysis show that air pollution collaborative governance is negatively related with the emission of industrial sulfur dioxide and indus-trial soot, and this result can not pass the significant test. From the result of subsample analysis, air pollution collaborative governance is significantly negatively related with the emission of industrial sulfur dioxide, but it is not significantly related with the emission of industrial soot. Cities have differences in promoting emission reduction of different pollutants, and the pollutants with lower emission reduction diffi-culty are often given priority to be completed. Seeing from time effect, there is time lag for the influence of air pollution collaborative gov-ernance on the reduction of pollutant emission, and the time lag is different among various pollutants reduction.
