Using data from a survey in Songzi County of Hubei Province, this article analyzes the relationship between children's gender and marriage form and their provision of old-age support to their noncoresiding parents in rural China. The results show that children's gender and marriage form have significant influence on their likelihood of giving financial and housework support to their parents, but no significant influence on the amount of financial support or their likelihood of supporting their parents with agricultural labor in peak agricultural seasons. Thus, the authors find that in Songzi, where both virilocal and uxorilocal marriages have been historically accepted and commonly practiced, sons and daughters play basically the same role in providing old-age support for their noncoresiding parents, as do virilocal and uxorilocal couples. The article discusses how these findings relate to current and future problems of old-age security and son preference in rural China.

中国历史上一直存在嫁娶和招赘两种婚姻形式。由于各种社会、经济、文化和人口因素的影响，在农村中嫁娶式婚姻占绝对主导地位，而招赘式婚姻则非常少见。本文利用陕西省略阳县和三原县的调查数据，对于应时性和制度性两种类型的招赘式婚姻的影响因素进行了比较研究。

Using data from a survey in Songzi county of Hubei province, this paper studies the influence of children's marriage form and individual factors on the division from their natal parents after marriage in rural China. The results reveal that among children with a brother, sons in virilocal marriages are more likely to undertake family division and it will occur earlier than for daughters in uxorilocal marriages. However, among children without a brother, behaviours in family division are not significantly different between sons and daughters. The majority of family division occurs in the first five years after marriage for sons and is distributed more or less equally over the first five years after marriage for daughters. Some children's individual factors including number of siblings also affect their likelihood of family division. Demographic, socioeconomic and cultural causes underlying this phenomenon as well as its social implications are also discussed.
