This paper examined the effect of air pollution joint prevention and control on pollution emissions in China. Specifically, based on the panel data of 290 cities from 2007 to 2021, taking the implementation of the "Air Pollution Prevention and Control Action Plan" as a natural experiment, the difference-in-difference-in-difference (DDD) model was used to explore the effect of air pollution joint prevention and control on haze pollution. Results show that air pollution joint prevention has a significant impact on pollutant emissions either as a whole or as a single pollutant. In terms of individual urban agglomeration, whether the Yangtze River Delta or the Pearl River Delta urban agglomerations, the air pollution joint prevention and control policy has a significant impact not only on the overall reduction of pollutant emissions but also on the reduction of single PM2.5 or industrial sulfur dioxide emissions alone. Environmental regulations have also achieved the effect of haze control in general and have a significant impact on the reduction of PM2.5 or industrial sulfur dioxide emissions. Environmental regulations also significantly reduced PM2.5 emissions in these three urban agglomerations. These findings provide a scientific basis and essential reference for understanding the implementation effect of regional joint prevention and control policies comprehensively and objectively.
本文考察了大气污染联防联控对中国污染排放的影响。具体而言，基于 2007 年至 2021 年的 290 个城市的面板数据，以实施《大气污染防治行动计划》为自然实验，利用三重差分模型（Difference-in-Difference-in-Difference，DDD）探究了大气污染联防联控对雾霾污染的影响。结果表明，大气污染联防联控无论是整体还是单一污染物，都对污染物排放有显著影响。就单个城市群而言，无论是长三角还是珠三角城市群，大气污染联防联控政策不仅对污染物排放总量的降低有显著影响，而且对单独的 PM2.5 或工业二氧化硫排放的降低也有显著影响。环境规制也普遍实现了雾霾控制的效果，对 PM2.5 或工业二氧化硫排放的降低有显著影响。环境规制还显著降低了这三个城市群的 PM2.5 排放。这些发现为全面、客观地理解区域联防联控政策的实施效果提供了科学依据和重要参考。
