区域一体化政策实施的民生福祉增进效应--基于“长江经济带发展战略”的研究

The Enhancement Effect of Regional Integration Policy Implementation on People's Well-Being--A Study Based on the Development Strategy of Yangtze River Economic Belt

基于2010-2020年285个地级市的面板数据,将“长江经济带发展战略”这一区域一体化政策的实施视为一项准自然实验,运用双重差分法研究区域一体化政策实施的民生福祉增进效应。结果表明:(1)长江经济带民生福祉水平呈现出下游>中游>上游的趋势,且2014年以后高于全国水平;(2)区域一体化政策的实施可以显著增进民生福祉,且具有城市规模异质性;(3)人口流动、外贸市场、产业结构升级与数字普惠金融是区域一体化政策实施增进民生福祉的关键路径。据此,应深化实施“长江经济带发展战略”,打造区域协调发展新样板;加快转变特大超大城市发展方式,有效促进人口合理流动;着力推动更高水平对外开放,扩大内需以增强国内大循环内生动力和可靠性;创新发展数字普惠金融,以数字技术支撑区域产业转型升级。

Based on the panel data of 285 prefecture-level cities from 2010 to 2020,this paper considers the implementation of Yangtze River Economic Belt development strategy as a quasi-natural experiment to study the enhancement effect of regional integration policy implementation on people's well-being using the difference-in-differences method.The results show that the level of people's well-being in the Yangtze River Economic Belt has a trend of downstream>midstream>upstream,and it is higher than the national level after 2014.Regional integration policy implementation can significantly enhance people's well-being and has city-scale heterogeneity.Population mobility,foreign trade market,industrial structure upgrading,and digital inclusive finance are the key paths for the enhancement effect of regional integration policy implementation on people's well-being.Therefore,it is necessary to deepen the implementation of the Yangtze River Economic Belt development strategy to create a new model of coordinated regional development,accelerate the transformation of the development of mega cities and effectively promote the reasonable flow of population,promote a higher level of opening up to the outside world,expand domestic demand to enhance the endogenous power and reliability of the domestic cycle,innovate and develop digital inclusive finance,and support the transformation and upgrading of regional industries with digital technology.
