Evolution Models of Urban Connectivity in the Yangtze River Delta in the Perspectives of Urban Hierarchy and Network:An Analysis of Big Data on Population Flows
摘要
Abstract
This paper examines inter-city population flows in the perspectives of ur-ban hierarchy and network through leveraging spatial and temporal big data.Based on a theoretical analysis of the methodology and standards for measuring urban con-nectivity as well as an assessment of their applicability,the paper highlights the fo-cal point of urban connectivity and proposes an index system for measurement.Uti-lizing the Yangtze River Delta urban agglomeration as an example,the paper quanti-tatively tracks the changes in urban connectivity from 2015 to 2020.Through hierar-chy analysis and cluster analysis,it distills six evolution models of urban connectiv-ity in the Yangtze River Delta and identifies exemplary cities for each model.Major findings are summarized in three aspects.First,the overall development trend of the Yangtze River Delta urban agglomeration is characterized by a weakening hierarchi-cal structure and stable network connectivity.Second,a relatively balanced hierarchi-cal structure has been formed within the Yangtze River Delta urban agglomeration,and in the national population mobility network,a few provincial capitals continue to play pivotal roles.Third,from the dual perspectives of hierarchy and network,cit-ies in the Yangtze River Delta can be categorized into six types according to the connectivity evolution model.Among them,Shanghai and Suzhou feature top and stable connectivity and a hierarchy-network equilibrium;Hangzhou and Nanjing dem-onstrate high and stable connectivity with the dominance of network over hierarchy;Hefei,Wuxi,Jinhua,and Ningbo are characterized by high and fluctuating connectiv-ity with the dominance of network over hierarchy.Three other models coexist with the aforementioned three.关键词
