摘　　要：本文采用中国2008-2019年285个地级市相关数据,运用PSM-DID方法研究长江经济带区域一体化提升城市经济增长的机制与效果。研究发现:(1)区域一体化显著推动长江经济带城市经济增长,一体化进程将人均地区生产总值提升了0.2399个单位。一体化进程对长江经济带上游城市经济增长推动作用不显著,而对中、下游城市经济增长推动作用显著;(2)区域一体化通过资本流动、金融发展为中介,间接促进城市经济增长。Based on the relevant data of 285 prefecture-level cities in China from 2008 to 2019,this paper uses PSM-DID method to study the mechanism and effect of regional integration of the Yangtze River Economic Belt on promoting urban economic growth.The findings are as follows.First,regional integration of the Yangtze River Economic Belt significantly advanced the growth of cities along the belt,and increased Gross Regional Product per capita by 0.2399 units.The integration process played an insignificant role in promoting economic growth of cities in the upper reaches of the Yangtze River Economic Belt,but the contrary was the case for those in the middle and lower reaches.Second,regional integration also promoted urban economy through such indirect intermediaries as capital flow and financial development.
