留守经历对新生代农民工工作流动的影响--基于2015年北京市数据的实证检验

本文基于2015年北京市新生代农民工的微观调查数据，在利用倾向得分倒数加权法纠正样本的选择性偏差以后发现：（1）新生代农民工过高的工作流动频率在一定程度上与其普遍的留守经历有关；（2）不同类型的留守形式和留守时间对工作流动的影响有所不同，完全留守、长期留守者表现出更高的工作流动性；（3）相同的留守行为对工作流动的影响存在明显的性别差异，男性农民工更易受到童年时期留守经历的影响。上述结论的政策启示在于：在关注留守经历及其所带来的影响差异的同时，也应避免留守问题的代际传承。

The Effcet of Left-Behind Experience on Job Mobility of New Generation of Migrant Workers:A Survey in Beijing in 2015

Based on the data of a survey of the migrant workers of new generation in Beijing in 2015 , and using propensity score weighting method to correct the sample selection bias, the paper finds that: 1. The job mobility frequency of the migrant workers of new generation correlate with their Left-Behind experience;2. The differences in Left-Behind experience in types and and time affect their job mobility, i.e. Those completely Left-Behind, or Left-Behind long time show a higher job mobility; 3. There are significant gender differences in the effect on job mobility in those with same left-behind experiences, and the male migrant workers are more likely to be influenced by the Left-Behind experience of childhood. The above mentioned findings have some policy implications: social policies concerned should both focus on the effects of left behind experience of the children and its inter-generational transition.
