Research on the Coordinated Development Effect of Urban Function Division——Empirical evidence based on satellite lighting data of Guangdong-Hong Kong-Macao Greater Bay Area
As the economic factors in China continue to display a trend of classification agglomeration in central cities and peripheral cities,the division of labor within urban clusters is gradually shifting from traditional product division to spatial functional division.This paper utilizes satellite light data from the Guangdong-Hong Kong-Macao Greater Bay Area to construct an income gap indicator,exploring the coordinated development effect of urban functional division.The study finds that urban functional division can significantly narrow the income gap between central and peripheral cities in the Greater Bay Area.Even after considering different measurement methods and endogeneity issues,the conclusion remains robust.The efficiency of resource allocation is identified as an important mechanism by which urban functional division reduces the income gap between central and peripheral cities in the Greater Bay Area.Based on this,it is recommended to optimize the industrial structure and promote the alignment of industrial layout with urban functional positioning;strengthen industrial collaboration to leverage the radiative driving effect of central cities;and enhance inter-city government cooperation to eliminate barriers to factor mobility.
