农村转移劳动力的供给弹性——基于微观数据的估计

Labor Supply Elasticity of Migrant Workers

增加农村转移劳动力的供给是促进工业化和城市化的必然要求,本文考察工资上涨能否增加转移劳动力供给。将劳动供给弹性区分为外出持续时间弹性和外出的参与弹性。基于微观调查数据,发现外出持续时间弹性远小于外出参与弹性,提高工资可以增加外出打工的可能性,但对外出持续时间影响较小,男性的时间弹性为0.40,女性为0.68。时间弹性在不同群体间表现出较大差异,工资对较高教育程度者、老一代的外出时间并没有影响。

Industrialization and urbanization call for more supply of migrant workers. We investigate whether increasing wage can lead to more migrant work- ers and longer stay in urban areas. Labor elasticity is distinguished into two as- pects, duration elasticity and participation elasticity. Using rural household sur- vey data, we find that the duration elasticity is much smaller than participation e- lasticity. Increasing wage will increase the probability of working out, but has lit- tle effect on the duration of staying outside. Duration elasticity is 0.40 and 0.68 for male and female migrant workers respectively. There are differences of dura- tion elasticity across groups. Those of lower human capital and younger generation have higher duration elasticity than those of higher human capital and older gener- ation.
