Spatial Spillover,Boundary Effect,and Spatial Convergence of Regional Economy in China:Based on Solow Enhanced Quantitative Model
The spatial spillover and the boundary effect are two important factors to evaluate the regional economic growth.This paper introduces the space variable to build a Solow enhanced quantitative model.Then,the spatial lag model and the spatial Doppler model are used to estimate the data of 280 cities in China from 2001 to 2016.The results show that there is a significant spatial spillover effect in China's urban regional economic growth convergence.The absolute convergence rate is the fastest in the western region's economy,while that of the Yangtze River Delta,the Pearl River Delta and the Bohai Sea Rim is basically the same,which suggests that there is a general spatial convergence effect in China's regional economy.And the urban regional economic growth has a significant boundary effect,but in recent years the boundary effect is on the decline.The regional research also shows that in China's eastern region there is no boundary effect which is noticeable in the central and western regions,the Yangtze River Delta,the Pearl River Delta and the Bohai Sea Rim.In addition,the spatial spillover effect of technology is the most significant in the eastern region,which indicates that the spatial spillover effect on economy is the most significant and the spatial convergence phenomenon is also more evident in the eastern region because of the highest degree of marketization and the fastest diffusion of technology in the eastern region.On this basis,this paper puts forward corresponding countermeasures and suggestions.
