A Case Study on the Synergy Measurement of the Polycentric Spatial Structure in Shenzhen
This paper builds a theoretical framework for measuring the synergy of polycentric urban spatial structure based on centrality,functional connectivity and agglomeration level indexes,and conducts an empirical study using Shenzhen as an example.The study finds that the polycentric spatial structure is evolving towards a trend of networkization,the agglomeration capacity of major urban centers continues to strengthen,the independence of peripheral groups is growing,and the importance of hub centers is increasingly evident.Furthermore,by using functional connectivity and agglomeration level indexes to measure the degree of connectivity and flow of elements between centers,and to evaluate each center's agglomeration capacity,the paper effectively measures the spatial structural synergy of polycentric cities.This is a comprehensive measurement method that reflects the characteristics of functional connectivity and spatial agglomeration.It has excellent theoretical and practical significance for solving the problem of collaborative measurement of polycentric spatial structures within mega cities.
