农民工过度劳动行为的同群效应研究

Peer Effectsin Overwork of Migrant Workers

基于劳动者的群体决策特征探讨农民工过度劳动问题,可以为缓解过度劳动创设有效政策干预提供参考。本文使用中国流动人口动态监测调查数据,从同群效应角度研究农民工过度劳动行为的群体特征和作用机制。利用两阶段最小二乘法估计发现,其他情况不变的条件下,同区县农民工过度劳动比例每增加1个百分点,农民工个体过度劳动的概率显著增加0.73个百分点。机制分析发现,同群农民工之间的信息传递和社会模仿以及形成的收入渴求是同群效应发挥作用的重要机制。异质性分析发现,男性且低学历农民工的过度劳动行为具有更强的导向效应。本文研究证实了过度劳动行为决策的群体性特征,利用同群效应可以实现劳动力市场治理效果的延展性。

Exploring the issue of migrant workers’overwork based on the group decision-making characteristics of workers can create effective policy interventions to alleviate overwork.This paper uses China Migrants Dynamics Survey to study peer effects in overwork of migrant workers,and analyzes the group characteristics and mechanism of the peer effects.Using 2SLS estimation,we find that,all else being equal,for a 1%increase in the proportion of overwork by migrant workers in a county,the individual overwork of migrant workers increases significantly by 0.73%.The mechanism analysis shows that information transmission,social imitation,and income craving formed by migrant workers in the same community are important mechanisms of the peer effects.The heterogeneity analysis shows that,on average,the overwork of male migrant workers with low education in the same county has a stronger guiding effect.Thisstudy confirms the group characteristics of overwork,and that the peer effects can be used to generate an extended effect ofthe labor market governance.
