人口流动对江苏省基本公共服务供给水平的门槛效应研究

Threshold Effect of Population Flow on the Supply Level of Basic Public Services in Jiangsu Province

人口流动是精准配置公共服务资源的重要参考。基于江苏省2008—2020年的面板数据,研究人口流动对基本公共服务供给水平的门槛效应。结果显示,人口流动对基本公共服务供给水平具有双门槛效应,即基本公共服务供给水平随人口流动规模的扩大而降低,降低幅度随着人口流动变量跨过门槛值而下降。经济发展水平与产业结构均能显著提升基本公共服务供给水平,财政自主权提升不利于公共服务供给水平的提高。

Population flow is an important reference for accurately allocating public service resources.The study analyzes the threshold effect of population flow on the supply level of basic public services based on the panel data of Jiangsu Province from 2008 to 2020.The results show that population flow has a double threshold effect on the supply level of basic public services,i.e.the supply level of basic public services decreases with the expansion of the scale of population flow,and the reduction range decreases with the population flow variable crossing the threshold value.Both the level of economic development and industrial structure can significantly improve the level of public service supply,but the improvement of financial autonomy is not conducive to the improvement of public service supply level.
