摘　　要：分析城市群空间结构的演变及驱动因素,是实现我国区域协调发展的重要内容。本文基于我国八大城市群的空间结构,详细刻画了城市群空间结构的演变特征,并探讨了影响城市群空间结构演变的驱动因素。研究结论如下:(1)京津冀城市群、长江三角洲城市群、珠江三角洲城市群、长江中游城市群、中原城市群和哈长城市群的空间结构趋于多中心,成渝地区双城经济圈和关中城市群的空间结构趋于单中心;(2)时间差异上,2014年前八大城市群空间结构趋于稳定结构,2014年后部分城市群趋于单中心的空间结构,区域差异上,东部和中部地区城市群空间结构相对偏向于多中心结构,西部地区城市群空间结构更偏向于单中心结构;(3)城市群空间结构的演变主要受自然地理因素、社会经济因素、政府干预、地区差异和城市群内部差距等因素的影响,其中人均GDP对城市群空间结构的影响呈现倒“U”型的非线性特征。因此,依托城市群中心城市带动周边发展,缩小城市群内部发展差距,尊重城市发展规律,是推动区域协调发展的关键举措。The analysis of the evolution and driving factors of urban agglomeration spatial structure is an important content to realize the coordinated development of our country's regions.Based on the spatial structure of eight urban agglomerations in our country,this paper describes the evolution characteristics of the spatial structure of urban agglomerations in detail,and discusses the driving factors affecting the evolu-tion of the spatial structure of urban agglomerations.The conclusions are as follows:(1)The spatial structure of the Beijing-Tianjin-Hebei metropolitan area,the Yangtze River Delta urban cluster,the Pearl River Delta urban agglomeration,urban clusters in middle reaches of the Yangtze River urban,the Central Plains urban agglomeration and the Harbin-Changchun megalopolis tends to be multi-center,the spatial structure of Chengdu and Chongqing economic circle and the Guanzhong plain urban cluster tends to be single-center.(2)In terms of time difference,the spatial structure of the eight urban ag-glomerations tended to be stable before 2014,and some urban agglomerations tend to be single-center af-ter 2014.In terms of regional differences,the spatial structure of urban agglomerations in the central and eastern regions is more polycentric,while that in the western region is more monocentric.(3)The evolu-tion of the spatial structure of urban agglomerations is mainly influenced by the factors of physical geogra-phy,social economy,government intervention,regional differences and the internal disparities of urban agglomerations,the impact of per capita GDP on the spatial structure of urban agglomerations shows an in-verted U nonlinear characteristics.Therefore,it is a key measure to promote regional coordinated develop-ment to rely on the central city of urban agglomeration to promote peripheral development,narrow the de-velopment gap within urban agglomeration,and respect the law of urban development.
