人口流动与儿童心理健康的异质性

利用中国家庭动态调查（ CFPS）2012年数据，以儿童问卷中心理健康量表的测量结果为因变量，以反事实因果推论框架为基础，利用倾向得分匹配方法和异质性效应模型，探讨了人口流动对儿童心理健康的异质性影响作用。分析结果表明，儿童自身的流动会改善部分儿童的心理健康，但并不适用于全部儿童；越不可能流动的儿童，如果他们流动以后，其心理健康改善的幅度也越大；而父母亲的流动在某种意义上并不会影响留守儿童的心理健康。这些结果反映了人口流动的异质性影响作用。

The Heterogeneous Effect of Migration on the Psychological Status of the Relative Children

The paper employs the survey data of Chinese Family Panel Studies ( CFPS) in 2012 to describe the heterogeneous effect of migration on the psychological status of the respective children, based on the counter?factual causal inference framework. The results show that the migration of children could benefit for part of the children, but not for the whole migrant children: the less possible to move, the more beneficial return of psychological status from the movement; but the effect of parents’ migration do not have significant effects on the psychological status of left?behind children. The findings show the heterogeneous effect of migration, to which should be paid more attentions.
