华北地区城市大气环境质量影响因素的空间计量经济分析——基于自然地理要素的拓展

选择气象条件相似的华北地区28市(盟)作为研究样本,在验证了城市大气环境质量之间的空间关系后,将自然地理要素抽象化并引入空间计量经济模型,基于传统EKC模型论证了经济、社会和自然地理要素对地区大气环境质量的影响。分析结果表明:地形种类应是华北地区大气环境质量(PM 2.5、PM 10、SO 2)的主要影响因素,资源型城市属性在一定程度上会加重PM 10和SO 2的污染程度,其他诸如人均收入、人口密度、毗邻沙漠、拥有海岸线等因素对大气环境质量的影响总体上不太显著;仅在对NO 2污染物指标的回归中,可以发现显著的EKC效应。

Spatial Econometric Analysis of the Influencing Factors of Urban Atmospheric Environmental Quality in North China--An Extension Based on Physical Geographic Elements

The essay selects 28 cities(leagues)in North China with similar meteorological conditions as the research samples.After verifying the spatial relationship of atmospheric environmental quality among cities,the physical geography elements are abstracted and introduced into the spatial econometric model,and then the impact of economic,social and physical geography factors on regional atmospheric environmental quality is explored based on the traditional EKC model.It’s concluded that:the topography should be the main influencing factors of atmospheric environmental quality(PM2.5,PM10,SO2)in North China;the resource-based urban attributes will aggravate the pollution degree of PM10and SO2to a certain extent,and other factors such as per capita income,population density,being adjacent to desert,and coastline have less significant impact on atmospheric environmental quality;a significant EKC effect can be found only in the regression of NO2pollutant indicators.
