Abstract:

By means of spatial analysis and econometric models, the spatio-temporal correlation characteristics and effects between PM2.5 pollution and industrial eco-efficiency of prefecture-level cities in China from 2004 to 2016. The results show that: (1) Industrial eco-efficiency and PM2.5 shows a pattern of spatio-temporal staggered distribution. Areas with high PM2.5 pollution are mainly concentrated in the North China Plain and the middle and lower reaches of the Yangtze River, while high industrial eco-efficiency areas are distributed in coastal cities such as the Yangtze River Delta, the Pearl River Delta and the Bohai Rim Economic Zone, and a few major cities in the urban agglomerations of central and western China. (2) There is reciprocal interaction relationship between industrial eco-efficiency and PM2.5 pollution. Industrial eco-efficiency has a negative cumulative effect on PM2.5 pollution, and shows a "U-shaped" pattern, while the influence of PM2.5 pollution on industrial eco-efficiency is manifested by the positive cumulative effect of "inverted U-shaped" change. (3) Industrial eco-efficiency and PM2.5 pollution have significant spatio-temporal association, and the evolution of different types of spatio-temporal correlation keeps higher stability. Thereinto, the high industrial eco-efficiency and the high PM2.5 pollution regions are mainly concentrated in the urban agglomerations of the Beijing-Tianjin-Hebei region, the Shandong Peninsula and the Yangtze River Delta; the low industrial eco-efficiency and the low PM2.5 pollution regions are mainly distributed in the urban agglomerations of the Poyang Lake, the Guanzhong and the western region, as well as in a few cities in the northeast region. (4) Overall, industrial eco-efficiency has a significant and robust positive effect on PM2.5 pollution, but shows significant spatial heterogeneity. Specifically, the industrial agglomeration level, technological innovation and urban greening rates have a significant negative impact on PM2.5 pollution, while the effect of other variables is not significant.
