普惠金融减贫效应的区域差异及门槛特征研究——基于省级面板数据的实证分析

Study on the Regional Differences and Threshold Characteristics of the Poverty Reduction Effect of Inclusive Finance——An Empirical Analysis Based on Provincial Panel Data

本文基于2005—2017年全国31个省份的面板数据,运用空间面板模型对普惠金融发展与贫困减缓的关系进行实证检验,结果表明,普惠金融发展和贫困程度都存在空间集聚特征,从全国层面来看,普惠金融发展具有显著的减贫效应;从区域层面来看,普惠金融的减贫效应存在异质性,呈现出东强西弱的区域特征。在此基础上,进一步运用面板门限回归模型对普惠金融减贫效应的门槛特征进行实证分析,结果表明,普惠金融减缓贫困还存在显著的门槛效应,当经济发展越过某一门槛时,普惠金融的减贫效应会显著增加。

Based on the panel data of 31 provinces from 2005 to 2017 in China,this paper uses spatial panel model to have an empirical test on the relationship between inclusive financial development and poverty alleviation.The results show that both the development of inclusive finance and the degree of poverty in China have the characteristics of spatial agglomeration.From the national perspective,inclusive finance has a significant effect on poverty reduction;from the regional perspective,the poverty reduction effect of the inclusive finance has heterogeneity,which presents strong in the eastern China but weak in the western ones.Based on this occasion above,the panel threshold regression model is further used to analyze the threshold characteristics of inclusive financial poverty reduction effect.It is found that there is still a prominent threshold effect in inclusive financial poverty alleviation.When economic development crosses a certain threshold,the poverty reduction effect of inclusive finance will increase significantly.
