探讨子女留守决策对农民工家庭的经济影响,对解决留守儿童问题有重要意义。本文使用CHIP2013流动人口数据,使用工具变量法克服能力偏差导致的内生性问题,讨论了农民工子女留守对父亲收入与家庭支出的影响,探究留守问题产生的根源。研究发现:子女随迁会提高父亲的收入,但控制了内生性问题后发现,子女是否随迁对父亲的收入没有影响。暗含着能力高的父亲,更可能让子女随迁。同时子女随迁会增加农民工家庭的支出,尤其是教育和住房支出,不利于进行经济积累。此外,子女在县城、地级市以及省会城市读书对家庭支出的影响差别较大。
Studying the economic impact of left-behind children’s decisions on migrant workers’ families is of great significance to solving the problem of left-behind children. This paper uses the CHIP2013 floating population data to overcome the endogenous problems caused by capacity deviation using the tool-based variable method. It discusses the impact of left-behind children’s income on father’s income and family expenses, and explores the root causes of the left-behind problems. The study found that: children with relocation will increase his father’s income, but control of the endogenous problems found that whether the child’s relocation of the father’s income has no effect. Implied ability of high fathers, more likely to allow their children to move with them. At the same time, children’s relocation will increase the expenditure of migrant workers’ families, especially education and housing expenses, which is not conducive to economic accumulation. In addition, children’s reading in the county, prefecture-level cities and provincial capitals has a far-reaching impact on household expenditure.
