长三角地区金融发展影响城乡收入差距的门限效应研究

A Study on the Threshold Effect of Financial Development in the Yangtze River Delta Region on the Income Gap between Urban and Rural Areas

城乡收入差距受多种因素影响,金融作为现代经济的核心是否会对城乡收入差距产生影响以及如何影响等问题值得研究。文章选用长三角地区1990-2015年的面板数据作为样本构建门槛模型,研究结果表明:从整体上看,在样本观测期内,金融发展对城乡居民收入差距的影响呈现出明显的非线性特征,当金融相关系数FIR为1.3593时出现了明显的拐点。同时研究发现:长三角地区金融发展和城乡收入差距的关系正位于倒"U"型曲线的附近,处于由正相关关系向负相关关系转变时期。为此建议在未来金融改革过程中,应更多地将金融资源投向有利于缩小城乡收入差距的部门,使更多的低收入群体享受金融的服务,缩小城乡居民收入差距。

The gap between urban and rural income is affected by many factors, and whether financial as the core of modern economy will affect the income gap between urban and rural areas and the specific impact mechanism is worth studying.This paper selects the panel data of the Yangtze River Delta region during 1990-2015 as samples to build the threshold model, the results show that : on the whole, in the sample period, the impact of financial development on the income gap between urban and rural residents showed obvious nonlinear characteristics, when the financial correlation coefficient FIR is 1. 3593 when the turning point was obviously. Meanwhile, the relationship between financial development and urban-rural income gap in the Yangtze River Delta is close to the top of the inverted "U" curve, which is in the positive correlation from negative correlation to negative related period of change. To this end, this paper suggested future financial reform process should be more financial resources to invest will help to narrow the urban-rural income gap between departments,so that more low-income groups access to financial services and narrow the income gap between urban and rural residents.
