本文利用我国2005-2014年间的省级面板数据,构建了全国整体以及东、中、西和东北部地区城镇发展对空气质量的影响因素模型。结果显示,无论在全国层面还是区域层面,经济增长与空气污染综合指数均呈U型关系,这与环境库兹涅茨曲线的倒U型假说相反;城镇化与空气污染综合指数呈倒U型关系;第三产业比重对空气质量的影响是正向的;建成区绿化覆盖率对空气质量的作用并不显著;私人汽车拥有量的增加则显著降低了空气质量。
Based on the provincial panel data from 2005 to 2014 in our country, this paper constructs a model of the influencing factors on urban air quality in urban areas as a whole as well as in eastern, central, western and northeastern China. The results show that both at the national and regional levels, the economic growth and the air pollution index show a U-shaped relationship, which is contrary to the inverted U-shaped hypothesis of the Environmental Kuznets Curve. The composite index of urbanization and air pollution is inverted U-shaped The relationship between the proportion of the tertiary industry and the air quality is positive. The effect of green coverage in the built-up area on air quality is not significant. The increase of the private car ownership significantly reduces the air quality.
