【摘要】：利用2003—2013年中国十大城市群100个地级市的面板数据研究城市群规模和对外开放程度对环境污染影响的门槛效应。结果表明:1)城市群规模与环境污染之间呈倒"N"型曲线特征,经历了"逐步缓解——恶化——得到好转"三个阶段。当城市群规模小于5 919.6万人时,环境污染随城市群规模的扩大而减少,城市群规模在5 919.6—9 790.67万人之间时将不利于环境质量改善,跨过这一区间后则有助于环境污染减少。2)城市群对外开放程度对环境污染的影响呈倒"U"型曲线特征,当外资利用水平小于225.047亿美元时会严重影响环境质量,在225.047—4 195.32亿美元之间时影响作用开始减小,超过4 195.32亿美元时则会促进环境质量的改善;目前我国十大城市群,除了长三角跨过第二门槛值之外,其他城市群外资利用均处于对环境产生负面影响阶段。3)产业结构的调整、高科技人力资源培养都将对环境质量改善有极大的促进作用。
[Abstract]:Using panel data of 100 prefecture-level cities in 10 urban agglomerations in China from 2003 to 2013, the threshold effect of urban agglomeration scale and degree of opening to the outside world on environmental pollution is studied. The results show that: 1). The relationship between the scale of urban agglomeration and environmental pollution is characterized by inverted "N" curve. When the scale of urban agglomeration is less than fifty-nine million one hundred and ninety-six thousand people, the environmental pollution decreases with the expansion of urban agglomeration scale. The scale of urban agglomeration in the range of 5,919.6-9,790.67 million people will be detrimental to the improvement of environmental quality. After crossing this interval, it will help to reduce environmental pollution. 2) the influence of the opening degree of urban agglomeration on environmental pollution is characterized by inverted "U" curve. When the level of foreign capital utilization is less than twenty-two billion five hundred and four million seven hundred thousand US dollars, the environmental quality will be seriously affected, and the effect will begin to decrease in the range of 225.047-419.532 billion US dollars. More than $four hundred and nineteen billion five hundred and thirty-two million will improve the quality of the environment; At present, the top ten urban agglomerations in China, except the Yangtze River Delta crossing the second threshold, the other urban agglomeration foreign capital utilization is in the stage of negative impact on the environment. 3) Industrial structure adjustment. The cultivation of high-tech human resources will greatly promote the improvement of environmental quality.

【正文快照】： 一、引言我国“十一五”规划明确指出,要以城市群为城镇化发展的主要形式,将中国城市分布看作是由各城市群“圈层”式的组织形式,去除了以往的“条状”认识,提出了以核心带动边缘、大城带小城的发展模式。“十三五”规划更是强调应强化中心城区与周边城镇的一体发展,促进形成
