健康变化对中国老年人自评生活质量的影响--基于 CLHLS数据的固定效应模型分析

摘要

The previous studies have found that the health status of the elderly was closely related to self⁃reported quality of life. But these studies generally used the cross⁃section data, and also tended to choose the single dimensional index to measure the health status. Using “Chinese Longitudinal Healthy Longevity Survey” ( CLHLS) data, from multi dimensions of health including body health, mental health and self⁃rated health, this paper tested the effect of health changes on the self⁃reported quality of life of the elderly in China with the fixed effects model. Our study showed that the improvements of body health, mental health and self⁃rated health among the elderly could improve their levels of quality of life. However, three dimensional indexes exerted different influences. The mental health and self⁃rated health played a mediating effect between body health and self⁃reported quality of life.%以往研究发现，老年人健康状况与自评生活质量之间密切相关。但这些研究一般采用截面数据进行分析，对健康的测量也往往选择单维的指标。本文以“中国老年健康影响因素调查”（ CLHLS）的跟踪数据为基础，运用固定效应模型，从肌体健康、心理健康和自评健康三个方面分析老年人健康状况的改变对他们自评生活质量的影响。研究结果表明，老年人肌体健康、心理健康和自评健康的改善，均能够提高老年人自评生活质量的水平，但是三者的影响程度是不同的，同时，心理健康和自评健康在肌体健康和老年人自评生活质量之间发挥着中介作用。
