Abstract: Based on the evolution of the megalopolis theories and the analyses of population census and statistical yearbook data，this study explores the issues of coordination development of Megalopolis’s population．Based on a clear distinction between the concept of core area and core city，and using methods of spatial autocorrelation and industrial structure deviation analyses for comparing the spatial scale，space structure of population and spatial coordination of industry between Northeast megalopolis in USA and Beijing-Tianjin-Hebei megalopolis in China，this study shows that for a typical megalopolis，its incubation process presents a significant stage development pattern．The population proportion of its core city rises at the beginning，and then declines．The spatial distribution of population shows a changing trend from single pole to multi growth poles．The spatial structure of population has both characteristics of aggregation and dispersion．The adjustment of industrial structure in core region has major implications to the coordination development within Megalopolis．

摘要： 基于城市群理论的演变过程,文章从空间视角出发,利用人口普查和统计年鉴数据分析了城市群人口发展的协调问题,讨论了典型世界级城市群的发展路径对新兴城市群孵化的借鉴价值。在明确区分城市群"核心区域"和"核心城区"概念的基础上,使用空间自相关分析和产业结构偏离度分析等方法,对美国东北部城市群和京津冀城市群人口空间规模、分布、结构以及产业空间协作状况进行了比较。结果表明:典型世界级城市群的孵化过程具有显著的阶段性特征,核心城区人口占比经历了"先升后降"的过程;人口空间分布存在由单核向多极转变的趋势;人口空间结构兼具聚集和分散的双重特性;核心区域的产业结构调整对于城市群的空间协作发展具有引导作用。
