基于面板门槛模型的我国金融发展对城乡收入差距影响机制研究

Analysis of the Influencing Mechanism of Financial Development on Urban-Rural Income Gap in China Based on Panel Threshold Model

本文依照八大经济区域的划分,利用面板门槛模型探寻我国金融发展对城乡收入差距作用的门槛特征及其区域差异。结果表明,我国金融发展对城乡收入差距的影响存在门槛效应,并且不同产业类型的地区存在方向与阶段上的差异。具体而言,商贸型地区出现完整的倒U型特征,工业型地区出现先扩大后放缓的形似倒U型左半部分的特征,其他地区则呈现线性正相关的特征。随着地区现代产业部门密集程度的上升,金融发展拉大城乡收入差距的效应展现出逐渐缩小的负相关规律。因此,政府在制定农村金融发展政策时应注意与地区产业相配合,以产业发展带动金融业的发展和居民收入的提高,以此减小城乡收入差距。

Dividing 30 provinces into eight areas according to their industrial agglomeration degree,this paper uses the panel threshold model to analyze the regional differences of financial development's threshold effect on urban-rural income gap in our country.The empirical results show that the threshold effect of financial development exists and differs in both directions and progress among regions.Specifically,a complete inverted-U curve has appeared in commercial regions while the industrial area has just shown the left side of the inverted-U curve.In the other regions,income inequality is in linear positive correlation with financial development.With the increase in intensity of modern industrial sector,the widening effect of financial development on urban-rural income gap gets weaker.Thus,the rural financial development policies should coordinate with the area's industry.In order to reduce the urban-rural income gap,rural industry should be developed so as to motivate the development of financial sector and the increase of income.
