“成本”视角下购房对家户生育行为的影响研究

The Impacts of House Purchasing on the Fertility Behavior in the Cost Constraint Perspective

本文以"成本"作为分析视角,通过建立生育行为存活模型对购房对家户生育行为可能产生影响的两种情况——"没房子不生孩子"与"买房子不敢生孩子"进行了分析探讨。研究发现,生育前购房较未购房的家户有相对较长的婚后至生育时间,且在房价高峰期购房的家户由于占据了较多的家庭资源,使房子对孩子的挤压效果更为明显,进而拖延生育时间;对于未购房在外租房的家户,由于需负担租金、难以获取家庭代际资源等其婚后生育时间较与原生家庭同住的家户有较长的婚后生育时间。

This paper tries to explore the potential effects of house purchasing on the family＇s fertility behaviors including that of no house and no kids and that of house purchasing disable the couples＇ children-bearing by establishing a survival model of fertility behavior in the perspective of cost constraint. It finds that the couples who purchased house have much late children-bearing behavior than the couples who purchase no house, and the couples who purchased house in the price peak have even late children-bearing and stronger squeezing effect of house purchasing on children bearing for its high occupation of family resources. The coupes renting house have late children-bearing behavior than the couples living with their parents,because the couples renting house to live need to afford the rents within their limited income while no resources support from their parents.
