中国农村劳动力流动对缩小城乡收入差距的实证研究——基于全国30个省级面板数据

An Empirical Study of China Labor Force Migration Influence on Narrowing Urban-rural Income Gap——Based on 30 Provincial Panel Data

针对我国劳动力跨地区乡城流动规模和城乡收入差距扩大的事实,利用全国30个省份面板数据,通过建立固定效应等计量经济模型,采用OLS和工具变量回归估计方法实证分析了中国跨区域的乡城劳动力流动对城乡收入差距的影响。研究表明:从分时间段来看,1992年之后,中国的劳动力流动对缩小城乡收入差距有显著作用;从分区域来看,中、西部的劳动力流动对缩小城乡收入差距有显著作用。

This empirical study, based on the scale of cross-regional rural-to-urban labor force migration and the widening of urban-rural income gap as well as the panel data from 30 provinces, analyzed the influence of China cross-regional rural-to-urban labor force migration on the urban-rural income gap by setting up an econometric model and adopting OLS and instrumental variable regression estimation method. The results show that in terms of time pe- riod China labor force migration has significantly narrowed the urban-rural income gap since 1992, and that in terms of areas the labor force migration in the middle and western areas has significantly narrowed the urban-rural income gap.
