选择机制,技能溢价与人口迁移——基于全国流动人口动态监测数据的经验分析

Selection Mechanism,Skill Premium and Population Migration:An Empirical Aalysis of the Floating Population Data National-wide Monitored Dynamically in China

本文运用全国流动人口动态监测数据检验了劳动力在迁移过程中的自选择假设,即低技能劳动力通常倾向于从技能回报率与收入差异较大的地区迁往技能回报率与收入差异较小的地区。实证结果表明:在我国,受教育程度较高的人群较受教育程度较低的人群有着更高的迁移倾向,而且地区间收入差距的扩大会降低迁移率,其主要原因在于受教育程度较低的人群的迁移倾向会下降;迁入地与迁出地的收入水平也是影响迁移动机的重要因素。

This paper tests the self-selection hypothesis that low-skilled labor are more likely to migrate out from the areas with lower and undifferentiated income expectance to the areas with higher and differentiated income expectancy based on the floating data collected by dynamic monitoring national-wide in China. The test shows a contrary tendency against the self-selection hypothesis. The population with higher education and skills boast of comparatively are more likely to migrate and the regional income gap can decrease the migration rate because of the lower migration intention of the population with lower eduction.
