摘　　要：功能多中心是城市群本质特征的反映,也是构建分工协作、功能完善的新型城镇化格局的重要举措。论文以中国19个城市群为研究对象,基于腾讯人口迁徙数据,分析了城市群在全国与区域尺度上的人口流动网络结构特征与功能多中心时空演化特征,并进一步探讨功能多中心的影响因素。研究发现:①中国城市群整体的区域功能多中心指数大于全国功能多中心指数,并朝多中心方向发展;优化提升、发展壮大和培育发展三种发展类型城市群的全国与区域功能多中心指数均存在较大差距。②大部分城市群的区域功能多中心指数大于全国功能多中心指数,符合尺度越大多中心指数越小的规律性;各城市群的功能多中心类型稳定,但演化方向具有差异性。此外,城市群功能多中心类型与城市群发展类型并没有明显的关系,城市群功能多中心类型具有复杂性。③人均GDP的提高降低了全国功能多中心指数,并且与区域功能多中心指数呈现“U”型关联;二三产业总值之比提高促进了全国功能多中心指数的提升;常住人口规模增加和互联网用户比重降低促进了区域功能多中心指数的提升。研究结果可为城市群空间结构发展战略的制定提供相关参考。Functional polycentricity is a reflection of the essential attributes of urban agglomerations,and an important way to build a new urbanization pattern of division of labor and cooperation with improved functions.Based on Tencent's population movement data from 19 urban agglomerations of China,this study analyzed the spatiotemporal change characteristics of population flow networks at the national and regional scales and functional polycentricity in urban agglomerations,and further explored the influencing factors of functional polycentricity.The results show that:1)The regional functional polycentricity index of urban agglomerations of China as a whole is larger than the national functional polycentricity index and evolves toward stronger polycentricity,and there is a large gap between the national and regional functional polycentricity indices of the three types of urban agglomerations.2)The regional functional polycentricity index of most urban agglomerations is larger than the national functional polycentricity index,which is in line with the general pattern that the larger the scale,the smaller the polycentricity index.The functional polycentricity type of each urban agglomeration is stable,but the direction of change differs.There is no obvious relationship between the functional polycentricity type of urban agglomerations and the type of urban agglomerations'development,and the type of urban agglomerations'functional polycentricity shows complexity.3)The increase in GDP per capita reduces the national functional polycentricity index and shows a"U"-shaped correlation with the regional functional polycentricity index.The increase in the ratio of the total value of the secondary and tertiary industries promotes the increase of the national functional polycentricity index,and the increase in the size of the resident population and the decrease in the proportion of Internet users promotes the increase of the regional functional polycentricity index.The results of this study can provide relevant references for th
