Evaluating PM2.5 -Related health costs in China-Evidence from 140 Chinese cities.

Abstract

In recent years, China's economy has grown rapidly, and the health condition of Chinese residents has significantly improved. However, this rapid economic and social development has also brought a series of environmental problems, such as serious haze pollution, of which the main contents are PM2.5 particles. The objective of this study is to quantitatively estimate the PM2.5 -related health costs in China. Based on city-level data from 140 major Chinese cities as well as the Beijing-Tianjin-Hebei, Yangtze River Delta, and Pearl River Delta city clusters in 2010, the value of a statistical life method based on willingness to pay was employed. Moreover, global and local Moran's I values were calculated to examine the spatial distribution of the health cost of haze pollution in China. In areas with heavy haze pollution or a high level of economic development, residents' health costs will also be higher. In addition, there is a spatial aggregation phenomenon in the spatial distribution of health costs in China, which is mainly in the form of "high-high" aggregation, with high-value cities converging with other high-value cities. The health cost of haze pollution in China is very considerable, and there are regional differences.
