【摘要】：通過構(gòu)建城市人均污染排放—人口規(guī)模模型,運用我國285個地級以上城市的面板數(shù)據(jù),對不同等級城市人口規(guī)模與環(huán)境的關(guān)系進行了實證研究。結(jié)果顯示:小城市人均污染排放量隨著城市人口規(guī)模的增加呈遞減趨勢;中等城市人均污染排放量隨著城市人口規(guī)模的增加呈先增加再減少的"倒U型"關(guān)系;大城市人均污染排放量隨著城市人口規(guī)模的增加呈"正N型"關(guān)系;特大和超大城市人均污染排放量隨著城市人口規(guī)模的增加呈"倒U型"關(guān)系;從全國范圍看,城市人均污染排放量隨著城市人口規(guī)模的增加呈"倒U型"關(guān)系。
[Abstract]:Based on the model of per capita pollution emission and population scale, this paper makes an empirical study on the relationship between population size and environment of different grade cities by using panel data of 285 prefecture cities in China. The results show that the per capita pollution emissions of small cities decrease with the increase of urban population size, while the average per capita pollution emissions of middle-sized cities increase first and then decrease with the increase of urban population size. With the increase of urban population size, the per capita pollution emissions of large cities show a "positive N-type" relationship, and the per capita pollution emissions of mega-and mega-cities show a "inverted U-type" relationship with the increase of urban population size. From a national perspective, per capita pollution emissions of cities are inverted U-shaped with the increase of urban population size.
