| Abstract: | The implementation of precise governance of haze pollution is an important measure to deal with haze pollution. Using the PM2.5 of 263 Chinese cities from 2001 to 2016, this study constructed a recursive partitioning analysis method of decision tree based on machine learning, quantified the interactions between haze pollution zoning factors and governance factors, and then identified the haze pollution governance regions and governance factors. The results show that: (1) Geographic location, administrative level, industrial structure, regional planning, and economic zone are the main factors to identify the precise governance regions of urban haze pollution in China. Based on these factors, four types of urban haze pollution governance regions were identified. (2) In coastal cities, increasing the level of economic development and reducing the proportion of the secondary industry are conducive to improving the level of haze pollution governance. In non-coastal cities, reducing population density is helpful for alleviating haze pollution. Furthermore, in non-coastal and non-provincial capital cities, improving the level of science and technology progress is beneficial for controlling haze pollution. (3) The long-term trend of urban haze pollution governance zoning factors in China is highly consistent with the national policies during the “Five-Year Plan” periods. Therefore, scientific policies and precise regulation are conducive to the Precise governance of haze pollution. |
