摘要
文章利用2005-2014年我国省会城市面板数据,通过主成分分析法构造城市规模综合指标,全面考察了城市规模对全国总体和对超大城市、特大城市和大城市地区雾霾污染的影响。研究发现:城市规模的扩大在全国整体范围上加剧了雾霾污染,但对超大城市、特大城市和大城市地区的雾霾污染均体现出抑制作用;无论是全国范围还是分地区看,经济增长与雾霾污染之间皆呈现U型曲线关系,环境库兹涅茨假说在我国并不成立;不同控制变量对雾霾污染的影响也具有不同表现。
The paper,using the panel data of China’s provincial capitals from 2005 to 2014,constructs the urban scale com？prehensive index by employing the principal component analysis and comprehensively investigates the impacts of city scale on the smog pollution of the whole country,large cities,mega cities and metropolitan areas. The study finds that the expansion of the scale of cities intensifies the smog pollution in the whole country,but presents the inhibitory impacts on the smog pollution in large cities,mega cities and metropolitan areas. The economic growth and the smog pollution show a U-shaped curve rela？tionship whether from the perspectives of country of region,the environmental Kuznets hypothesis is not established in China. Moreover,the impacts of different control variables of smog pollution are also different.
