Abstract
Based on the PM2.5 concentration values of 30 provinces in China from 1998 to 2016, this study empirically analyzes the influencing factors of smog pollution by using spatial Durbin model. The study found that smog pollution in China has significant spatial spillover effects and spatial characteristics of high-high (low-low) aggregation. And through the method of spatial Durbin model, it is found that the smog pollution in China is time-dependent due to the significant influence of its lag term. In terms of driving factors, it is found that there is a significant inverted U-shaped curve relationship between smog pollution and economic growth. In terms of driving factors, it is found that there is a significant inverted U-shaped curve relationship between smog pollution and economic growth. The industrial structure with high proportion of the second industry, urbanization measured by urban population, and coal-based energy structure significantly aggravate the smog pollution in our country. In view of the spatial spillover effect and time lag effect of smog pollution in China, it is necessary to strengthen regional joint prevention and control. And it is also supposed to optimize industrial structure, achieve clean and efficient use of resources, rationalize urbanization, and encourage public transportation and new energy vehicles.
Highlights
Since the reform and opening up, China’s economic development has grown rapidly, and the process of urbanization and industrialization has continued to advance
The results showed that the increasement of proportion of industrial added value would aggravate smog pollution, and the impact in coastal areas was worse
The analysis found that the energy structure had a significant correlation with smog pollution, and the sub-regional study found that the north smog pollution was more serious than the south
Summary
Since the reform and opening up, China’s economic development has grown rapidly, and the process of urbanization and industrialization has continued to advance. Along with the improvement of people’s living standards, environmental pollution has gradually become a problem that plagues society, es-. Y. Xue pecially in recent years, which has seriously threatened people’s daily life and health. The 2017 China Ecological Environment Bulletin shows that in 2017, only 99 of the 338 cities in China achieved environmental air quality standards, and the remaining 239 cities had excessive ambient air quality. Smog pollution spreads widely and it is difficult to control. Smog pollution becomes one of the most difficult problems in environmental protection. Sulfur dioxide, nitrogen oxides and respirable particulate matter are the main components of smog. These three pollutants especially PM 2.5 cause great harm to the human body, so smog will pose a great threat to public health
