Study on the Influencing Factors of Haze Pollution from thePerspective of Space--Taking the Yangtze River Delta Urban Agglomeration as an Example

In recent years, haze frequently occurs in the Yangtze river delta region. In order to explore the influencing factors of haze pollution, the paper uses panel data from 2006 to 2016 and spatial lag model to explore the influencing factors of PM2.5. The results show that there is an inverted u-shaped relationship between haze pollution and economic development. The increase of the tertiary industry and the progress of science and technology can improve haze pollution, while the increase of foreign direct investment and the continuous expansion of population will exert pressure on the environment. Finally, according to the research results of this paper, the corresponding policies are proposed..
