摘要利用2015—2018年腾讯人口迁徙大数据和社会经济统计数据,采用多中心结构测度等方法,对中国19个城市群的人口规模、流动特征和空间结构演化进行分析.结果表明:(1)从整体上看,中国城市群的形态多中心结构指数差异明显,且有微弱向单中心空间结构发展的态势,而功能多中心结构指数大多较低,但表现出不断上升趋势.(2)在多中心结构类型匹配方面,优化提升类城市群的功能多中心结构指数较高但形态多中心结构指数普遍偏低,发展壮大类城市群的形态多中心结构指数较高但功能多中心结构指数大多偏低,而培育发展类城市群内部存在不同匹配类型.(3)在多中心结构类型演替方面,优化提升类和发展壮大类城市群多中心化发展的趋势较为明显,而培育发展类城市群大多呈现单中心化发展趋势. Using the population flow frequency data and socio-economic statistics data from 2015 to 2018,this paper analyzes the population size,flow characteristics and spatial structure evolution of 19 urban agglomerations in China by using polycentric measurement methods.The main findings are as follows:(1)The morphological polycentric index among urban agglomerations has obvious differences and shows a weak monocentric trend,while the functional polycentric index of urban agglomerations is mostly low but shows an obvious rising trend.(2)In terms of the polycentric matching types,the functional polycentric index of upgrading urban agglomerations is relatively high,but the morphological polycentric index is generally low.The morphological polycentric index of developing urban agglomerations is relatively high,but the functional polycentric index is mostly low.However,there are different matching types within the fostering urban agglomerations.(3)In terms of the polycentric evolution,there is a clear trend of polycentric development in urban agglomerations for optimization and enhancement,as well as for development and growth.However,most urban agglomerations for cultivation and development exhibit a trend of monocentric development.The conclusions can provide support for formulating targeted polycentric development strategies for urban agglomerations.
