金融发展加剧了中国收入不平等吗？——基于门槛回归模型的证据

摘要

As a central variable of modern economy,the effect of financial development on income distribution is an emerging issue in macroeconomic field.This paper makes a systematic review of related studies,and summarizes the function mechanism of the effect of financial development on income inequality.Using China＇s provincial-level panel data from 1996 to 2009,it employs the threshold model proposed by Hansen in 1999 to estimate the effect of financial development on income inequality.The results show that financial development significantly intensifies income inequality in China and the effect of financial development on income inequality is featured by the threshold effect.Especially,in provinces whose economic variable cross a certain threshold value,the effect of financial development on income inequality is greater.%作为现代经济的核心变量,金融发展的收入分配效应是宏观经济领域的一个新兴议题。文章系统梳理了国内外研究文献,总结金融发展影响收入不平等的传导机制,并利用中国1996-2009年省际面板数据和Hansen（1999）的门槛模型,对金融发展的收入分配效应进行了估计。研究结果表明,在样本期间内金融发展显著加剧了中国收入不平等,而且金融发展的收入分配效应表现出鲜明的门槛特征,跨越特定门槛值省区的金融发展对收入不平等的影响更大。
