京津冀城市群城市规模分布及演进机制研究

Research on Hierarchical Distribution and Evolution Mechanism of the City Size of Beijing, Tianjin and Hebei Urban Agglomeration

基于1992～2016年京津冀城市群城区人口数据,运用等级钟理论、城市首位指数、位序规模法则等方法深入分析城市体系规模分布时序演化轨迹的特征。结果显示,京津冀城市群首位城市虹吸效应过于明显,对周边地区的辐射效应较弱,以至于首位城市与中小城市规模差距较大,城市体系规模结构不均衡。在此基础上,从自组织机制和他组织机制两个方面,探析京津冀城市群城市规模演化的内在机制与规律,这对于京津冀城市群城市体系规模结构的合理优化具有现实意义。

This paper studies the evolution mechanism of the city size distribution of Beijing,Tianjin and Hebei urban agglomeration from 1992 to 2016 through an analysis of the rank-clock,the first city index and the rank-size distribution.The results show that the siphon effect of the first city in the Beijing,Tianjin and Hebei urban agglomer.ation is too obvious,and the"radiation effect"on the surrounding areas is weak,resulting in a large gap between the size of the first city and the small and medium-sized cities,and an unbalanced scale structure of the urban system.On the basis of this,the paper analyzes the internal mechanism and regularity of urban scale evolution of Beijing,Tianjin and Hebei urban agglomeration from the two aspects of self-organization mechanism and other organization mechanism.The results will produce far significance for the rational optimization of urban scale structure of Beijing,Tianjin and Hebei urban agglomeration.
