The Effect of Functional Polycentric Spatial Structure on the Economic Performance of Urban Agglomerations
The functional polycentric spatial structure based on the theory of"flowspace"and network enables cities to interact with each other in their processes,and is an important driving force for the economic improvement of urban agglomerations.This paper uses traffic flow to construct the functional polycentric index of urban agglomerations,and makes an analysis of the role and transmission mechanism of functional polycentric spatial structure on the economic development of urban agglomerations.The research results show that:The perfect functional polycentric spatial structure can promote the common progress of all cities in the urban agglomerations,but the population size has a inhibitory effect on the economic performance of the functional polycentric spatial structure of the urban agglomerations.The functional polycentric spatial structure of urban agglomerations can promote the economic performance of urban agglomerations through borrowing scale and borrowing function effects,but these two effects only play a partial intermediary role,and cities in small urban agglomerations are more likely to borrow scale and borrowing function from each other,while cities in large urban agglomerations are less able to borrow scale and borrowing function from each other.Therefore,the current development goal should be to improve the economic performance of urban agglomerations,and promote the development of"multi-center functional"spatial structure of urban agglomerations.
