论中国城市群的界定和作用

On the Definition and Roles of City Clusters in China

改革开放以来,中国城市化进程加速,形成了具有中国特色的城市群空间组织模式,并成为国家空间发展的重心。本文首先回顾了城市群研究进展,认为城市群界定必须建立在都市区基础之上,并提出了六项界定指标;而后利用"五普"数据界定了13个城市群,并采用"五普"和"六普"数据分析了城市群的人口增长动态和城市化趋势。对长三角、珠三角和京津唐三大城市群在国家中的经济地位进行分析,并以珠三角为例,分析了其人口和经济集聚过程,认为由于珠三角极化发展态势未发生根本改变,广东省内核心-边缘格局仍将持续。

The rapid urbanization of China has formed a new spatial form of city clusters, which has been the core of national spatial development. This paper firstly reviews the problems in the study of city cluster, and puts forward that the definition of city cluster must be based on the definition of metropolitan area. According to six indicators, the paper uses the data of China fifth census to definite 13 city clusters with a population of at least 10 millions in 2000, and analyzes the growth trend of population of 13 city clusters using the data of fifth census and sixth census. Then, the paper measures the economic concentration index of Yangtze River Delta, Pearl River Delta and Beijing-Tianjin-Tangshan in national economy, and taking Pearl River Delta as a case to analyze the spatial agglomeration and dispersion. The conclusion is that it is uncertain whether the city clusters as growth poles can play a role of trickling down to the peripheral areas so as to reduce regional disparity.
