中文摘要：

本文基于中国老年人健康长寿调查项目的数据,采用Maddala的处理效应模型,研究亲子居住模式对老年人心理健康的影响。亲子共同居住显著改善了老年人的心理健康状况;老年人的身体健康状况、婚姻状况、日常生活能力、生活水平等因素都对其心理健康状况存在显著的影响;政府提供的养老和医疗保障也显著改善老年人的心理健康状况;传统上的“儿子偏好”和“多子多福”观念受到挑战。在中国家庭规模、结构和稳定性转变的背景下,要提高规模庞大的老龄人口的福利水平,政府在加大社会保障的范围和力度的同时,还需采取措施延续和拓展家庭的保障功能。

英文摘要：

This paper uses 2008 ＂Chinese Longitudinal Healthy Longevity＂ survey data and Maddala＇ s treatment effects model to conduct empirical study of the effect of parent-child living mode on the subjec- tive well-being of the elderly. In general, parent-child living together significantly contributes to active sub- jective well-being of the elderly, and helps restrain the negative side, and restrains the subjective negative well-being of the elderly. At the same time, the health status, marital status, abilities to perform ADLs （ac- tivities of daily living）, and living standard all have also remarkably improve the mental status of the elder- ly; the pension and medical insurance can significantly improve the subjective well-being of the elderly; the traditional ＂son preference＂ and ＂more sons more happiness＂ is challenged. Based on the background of family scale, structure and stability transformation of Chinese families, in order to improve the welfare of the elderly, it requires the government not only to strengthen the social security, but also take measures to continue and expand the family security functions.
