中、西部金融发展对城乡收入差距的影响研究

The Impact of the Central and Western Financial Development on Urban-Rural Income Gap

基于2009-2018年中国中、西部19个省份的面板数据,构建面板门槛模型与空间计量模型,研究中、西部金融发展对城乡收入差距的门槛性和空间依赖性.研究表明:中、西部金融发展与城乡收入差距呈非线性关系,金融发展对城乡收入不平等存在单门槛效应,当金融发展水平提高且跨过门槛值时,拉大收入差距的作用将会增强;中、西部省份城乡收入差距存在空间依赖性,且出现负向空间溢出;贸易发展、经济发展水平缩小城乡居民收入差距.

Based on the panel data of 19 provinces in central and western China from 2009 to 2018,the panel threshold model and spatial measurement model are constructed to study the threshold and spatial dependence of the financial development of central and western regions on the urban-rural income gap.This research shows that the financial development of the Midwest and the urban-rural income gap is nonlinear.Financial development has a single threshold effect on the inequality of urban-rural income.As the level of financial development increases and the threshold is crossed,its role in widening the income gap will increase;the urban-rural income gap in the central and western provinces is spatially dependent,and there is a negative spatial spillover;the trade development and economic development has narrowed the income gap between urban and rural residents.
