城市蔓延、生产性服务业集聚与污染排放——基于京津冀、长三角和珠三角城市群的实证研究

Urban Sprawl,Producer Services Agglomeration and Pollution Emission: Based on the empirical study of Beijing Tianjin Hebei,Yangtze River Delta and Pearl River Delta Urban Agglomeration

在我国城市化加速推进过程中,土地城市化快于人口城市化的城市蔓延问题日益凸显,引发土地低效利用、公共设施浪费和生态环境破坏等突出问题。本文分析城市蔓延、生产性服务业集聚与污染排放之间的内在联系,并利用2003~2015年京津冀、长三角和珠三角城市群的面板数据进行了实证研究。结果表明:城市蔓延加重了城市的污染程度,但生产性服务业的集聚发展、市场自由度的提高和经济发展水平的提升为实现污染减排创造了条件。因此,强化环境规制,发挥生产性服务业的支撑作用,使城市的空间扩张和产业结构调整相契合,有利于缓解城市生态压力,提升城市经济可持续发展能力。

In the process of accelerating urbanization in China,the urbanization of land is faster than that of population urbanization,and the problem of urban sprawl is becoming more and more prominent,resulting in inefficient use of land,waste of public facilities and destruction of ecological environment. This paper analyzes the internal relationship between urban sprawl,producer services agglomeration and pollution emission,and makes empirical research on panel data of Beijing Tianjin Hebei,Yangtze River Delta and Pearl River Delta Urban Agglomeration in 2003-2015 years. The results show that the urban sprawl aggravates the pollution level of the city,but the agglomeration development of the producer services,the improvement of market freedom and the promotion of economic development have created conditions for pollution reduction. Therefore,to strengthen environmental regulation,play the supporting role of producer services,the city space expansion and adjustment of industrial structure fit, thecity will help alleviate the ecological pressure,enhance the ability of city economic sustainable development.
