财产性收入增长、市场化进程与我国城乡收入差距——基于面板协整模型的实证分析

Property Income Growth,Marketization Process and China's Urban-rural Income Gap——Empirical Analysis Based on Panel Cointegration Model

使用1997～2009年中国30个省级行政区的数据,基于面板协整模型,对财产性收入增长、市场化进程与中国城乡居民收入差距的关系进行实证分析。结果表明:财产性收入的增长有利于缩小中国城乡间的收入差距;市场化水平的提高则加剧了城乡收入差距;从交互影响看,市场化水平的提高有助于增强财产性收入增长对城乡收入差距的抑制效应。对不同地区而言,上述影响从东部地区到西部地区呈递减趋势。

Based on panel cointegration model, the authors empirically study the relationship among property income growth, marketization process and China＇s urban-rural income gap by using data of 30 provinces from 1997 to 2009. Results show that property income growth can help to nar- row the income gap between urban and rural areas in China; the improvement of marketization lev- el widens the gap; from another angle, the improvement of marketization level is beneficial to en- hance the suppression effect of property income growth on urban-rural income gap. The above in- fluences decrease from eastern China to western China in different regions.
