农村地区分家时间研究:基于生命表的分析

Study on the Time of Family Division Based on Life Table

利用2012年"陕西省农村婚姻家庭变动研究调查"数据,本文采用生命表的分析方法构建了儿子(女儿)初婚后离开父母(公婆)的分家生命表,对农村地区分家时间的变动态势、分家时间在不同维度的分布特征进行了定量分析。研究结果表明:分家时间集中在初婚后三年之内,且分家比例随着结婚年数的增加逐渐减少。父母做主的婚姻方式和较高的彩礼比重推迟了分家时间;分家时间随兄弟个数增加提前且分家比例增加。

Based on the data of Marriage and Family Survey of the Rural Area in Shaanxi Province 2012, this paper constructed a life table of family division of son or daughter separating from parents or parents-in-law after their marriage to analyze the changing trend of family division time and its distribution characteristics in different dimensions. The results show that the majority of family division occurs within three year after marriage, and proportion of family division decreases gradually with the year increase of marriage. The marriages decided by parents and the marriages with higher betrothal gifts can postpone the time of family division, the less brothers there are in the family, the more delayed time of family division will be.
