Study on the Influencing Factor of Haze Pollution About the City Along Chinese “The Belt and Roadâ€

Abstract

Relationships between china’s rapid urbanization and air pollution has been one of the most visible problems. This paper based on the monitoring data of prefecture-level cities from March 2016 to February 2017, gathered from 181 cities along “the belt and roadâ€, we used the arcgis software to make a visual analysis of the distribution of air quality index(aqi) and proposed a new kind of spatial weight based on gravity model to establish spatial autocorrelation and spatial regression model by r software to quantitatively estimate the comprehensive impact and spatial variations of air quality and socioeconomic factors of the cities along “the belt and road†in china. The results show that a significant seasonal change and positive spatial dependence existed in air quality. The model of southern coastal area is low-low aggregation while high-high aggregation model appears in inner mongolia, shanxi and gansu province. In the view of space return, the aqi of those cities shows remarkable spatial spillover effect. The increase of per capita gdp and civilian car ownership has a significant positive effect on the increase of haze pollution degree, however, population density, foreign direct investment and urbanization rate have remarkable passive effect; additionally, the greening rate of urban built-up area on air pollution nearly does not remarkable.
