The Beijing-Tianjin-Hebei, Yangtze River Delta, and Pearl River Delta urban agglomerations were used as experimental groups, and other prefecture-level cities were used as control groups. Based on the annual monitoring values of pm2.5 in various cities in 2008-2016, the double-difference model was used to test the implementation effect of the Air Pollution Prevention Action Plan. The study found that the promulgation of “Ten of the Atmosphere” significantly improved the air quality of the Beijing-Tianjin-Hebei, Yangtze River Delta and Pearl River Delta urban agglomerations, and the emission reduction effect of the northern city pm2.5 was better than that of the southern cities, which may be common with winter heating in northern cities. The environmental pollution is more serious than in the south, and the policy effect is more significant. At the same time, environmental pollution has spatial relevance. It is necessary to strengthen regional collaborative governance, innovative mechanism measures, and play an important role in environmental pollution control in air pollution. |
