文章主要分析劳动力流动与缓解贫困的关系。迁移从总体上改善了贫困地区的贫困程度。通过非参数分析,作者发现贫困家庭和富裕家庭的家庭特征差异对于迁移决策越发重要。而且,禀赋不足的贫困家庭即便有迁移行为发生,其在劳动力市场上的表现也与其他人有所不同。结合对工资方程的分析,作者发现改善贫困家庭的人力资本水平不仅有助于贫困家庭利用迁移,也有助于贫困家庭在劳动力市场上获得更好的收益。 The article mainly analyzes the relationship between labor mobility and poverty alleviation. The migration has generally improved the level of poverty in poor areas. Through nonparametric analysis, the author finds that the differences in family characteristics between poor and affluent families are more and more important for migration decisions. Moreover, impoverished poor families have different performance in the labor market from others, even when relocation takes place. Combined with the analysis of wage equation, the author finds that improving the human capital level of poor families not only helps poor families to make use of migration, but also helps poor families to get better returns in the labor market.
