摘要
本文考察房价对出生性别比的影响及机制。基于2010年人口普查资料,发现当房价收入比上升1个单位,城乡地区出生性别比将显著下降0.2%,其中房价上涨显著降低农村地区的出生性别比,对城镇地区出生性别比没有显著影响。为克服潜在内生性问题,本文使用刀切法工具变量回归进行分析,研究结论稳健。进一步分析发现,房价上涨不仅通过性别替代机制直接降低各胎次出生性别比,而且通过生育数量机制降低各胎次生育率进而间接降低出生性别比。
In this paper we explore the impact of housing price on sex imbalance and the underlying mechanism. Using 2010 population census data, we find that when housing price to income ratio increases by 1 unit, sex ratio at birth will significantly decrease by 0.2%. While rising housing price has a significant negative impact on rural sex ratio, it exhibits an insignificant impact on urban sex ratio. We exploit Jackknife Instrumental Variables Approach to address the endogeneity issue, finding our main conclusion is robust. Further analyses indicate that rising housing price decreases sex imbalance not only through direct sex substitution channel, but also through indirect fertility rate channel.
