Title: Analysis of the Polycentric Structure of Yangtze River Delta Based on Passenger Traffic Flow
Abstract: Using flows of intercity buses and intercity CRHs(China Railway High-speed) in the Yangtze River Delta as proxies for the intercity passenger traffic flows,this paper analyzes the characters and trends of the polycentric structure of Yangtze River Delta from the perspective of relation intensity and organizational structure of urban node.It is found that the intercity relation network of the North and the South Wing in Yangtze River Delta is relatively independent,and the relations between the North Wing cities and Shanghai is more intensive than those between the South Wing cities and Shanghai.Furthermore,the relations among the North Wing cities are also more intensive than those among the South Wing cities. With regard to the city-region's spatial structure,Shanghai is the primary hub-city; Nanjing,Hangzhou and Ningbo are the secondary hub-cities;and Suzhou,Nantong and Wuxi are possibly the direct hinterland cities or even become included in the commuter zone of Shanghai metropolitan area.It is concluded that thenetwork + hierarchypattern is emerging in the Yangtze River Delta.This means that on the one hand,the polarization of Shanghai is strengthening,and on the other hand,the development of industries and infrastructure is going to be envened out in the whole city-region.
