中文摘要：

本文利用2002-2008年中国老龄健康长寿影响因素跟踪调查（CLHLS）数据,在倾向值加权的基础上,采用含有frailty因子的Cox回归分析法,考察居住安排变化对老年人死亡风险的影响。研究结果表明,居住安排变化对老年人死亡风险存在影响,其中＂与子女同住变为不同住＂老人的死亡风险最高。研究结果还表明,考虑了脆弱性因子的回归系数绝对值大于没有考虑脆弱性因子的回归系数绝对值。在本研究中,没有考虑脆弱性因子的＂同住变为不同住＂低估了其对死亡风险的作用,而＂不同住变为同住＂以及＂一直同住＂则高估了其对死亡风险的作用。

英文摘要：

Based on the CLHLS 2002-2008 data, this article uses propensity score weighting method and frailty Cox models to examine the effect of change of living arrangements to elderly mortality risk. Results show changes of living arrangements affects elderly mortality risk. From co-residence with their adult children to non-co-residence with their adult children, elderly mortality risk is highest in all change types. Resuits also show the absolute values of coefficient in frailty Cox models are higher than those in Cox models. In this article, effect from co-residence with their adult children to non-co-residence with their adult children is underestimated, while effect from non-co-residence with their adult children to co-residence with their adult children and always co-residence with their adult children are overestimated.
