There has been some research on factors affecting China's rising sex ratio at birth (SRB), but the spatial dependence has been largely neglected. With China's census and sample survey data and the dynamic spatial Durbin model; we analyzed the changes in SRB in China. We found that SRB and its influencing factors were spatially correlated at the provincial level. For direct effects; urbanization significantly reduced SRB in this region; while strict family planning policies increased SRB in the local region. For indirect effects; the increase in per capita Gross Domestic Product and urbanization led to an increase in the SRB of the neighboring regions through population mobility. By comparison; educational improvement in one region benefited the neighboring provinces and reduced SRB.
已有一些研究关注影响中国出生人口性别比升高的因素,但这些研究在很大程度上忽略了空间相关性。本文利用中国的普查和抽样调查数据以及动态空间杜宾模型,分析了中国的出生人口性别比变化情况。研究发现,省级水平的出生人口性别比及其影响因素存在空间相关性。具体而言,在直接效应方面,城市化显著降低了该地区的出生人口性别比,而严格的计划生育政策则提高了当地的出生人口性别比。在间接效应方面,人均国内生产总值和城市化水平的提高通过人口流动导致周边地区的出生人口性别比上升,而一个地区教育水平的提高则有利于周边省份,降低了出生人口性别比。
