摘　　要：在新型城市化稳步推进的过程中,城市群越来越受到政界和学术界的高度重视,但也毋庸置疑,我国城市群发展不平衡不充分现象比较突出,本文基于国家尺度和城市群尺度探索了我国19个城市群的空间分异特征。基于国家尺度,选取代表城市群基本特征的8个指标,定量测度了19个城市群的发展水平,研究表明:我国城市群发展水平存在“两强三高七中七弱”现象,空间分布极不平衡,总体上具有“南高北低,东西递减”的格局,“东、中、北、西”四大板块分异明显。基于城市群尺度,以构成城市群基本地域单元的城镇化率为变量,运用空间自相关等方法,判定了19个城市群的空间结构,研究表明:5个城市群呈聚集型空间结构,8个城市群呈非聚集型空间结构,6个城市群呈随机型空间结构。In the process of new urbanization,urban agglomerations have been paid more and more attention by the political and academic circles.However,there is no doubt that the unbalanced and inadequate development of urban agglomerations in China is quite prominent.This paper explores the spatial differentiation characteristics of 19 urban agglomerations in China based on the national scale and urban agglomerations scale.Based on the national scale,8 indicators representing the basic characteristics of urban agglomerations were selected to quantitatively measure the development level of 19 urban agglomerations.The research shows that:the development level of urban agglomerations in China has the phenomenon of"two strong,three high,seven medium and seven weak",and the spatial distribution is extremely unbalanced.On the whole,there is a pattern of"high in the south,low in the north,decreasing in the east and west",and the four plates of"east,central,north and west"are obviously differentiated.Based on urban agglomerations scale,this paper,taking the urbanization rate that constitutes the basic regional unit of urban agglomerations as the variable,using the method of spatial autocorrelation,determine the spatial structure of 19 urban agglomerations.The research shows that 5 urban agglomerations have clustered sptial structures,8 urban agglomerations have non-clustered spatial structures and 6 urban agglomerations have random spatial structures.
