社会资本对西部贫困地区农村老年人健康质量的影响路径——基于联立方程模型的中介效应检验

The Path about the Social Capital Effecting on Health of Elderly in Poverty Rural of the Western :A Testing Mediation Based on Simultaneous Equations Model

我国正处于人口老龄化的加速时期,老年人健康质量问题愈发突出。已有研究证实社会资本是影响健康的主要因素之一,但对于社会资本影响老年人健康质量路径的研究相对不足。文章基于西海固地区的微观数据,以生活方式为中介变量,采用联立方程模型,分析社会资本对老年人健康的影响效应及其路径。研究发现,社会资本对老年人总体健康质量具有显著影响,其中,社会资本的直接效应是0.638,生活方式产生的中介效应是0.108;社会资本不仅对老年人生理、心理、社会健康产生直接影响,且通过生活方式对老年人生理、心理健康产生间接影响,但是生活方式的中介效应弱于社会资本的直接效应。

Now the step of population aging is accelerating in China,and the health of elderly tends to be more concerned. Previous researches have indicated that social capital is one of the major factors affecting health,but it is rare to focus on the path of the social capital influencing on the elderly health. Based on survey data from Xi-Hai-Gu Area we use lifestyle as a mediator to study on the effect and path of social capital on the health of the elderly through simultaneous equations model. The empirical study shows that the social capital impacts on the health of the elderly significantly,of which directly effect is 0. 638 and mediating effect by the way of lifestyle is 0. 108.Not only are there direct effect on the physiological and the mental health of elderly by social capital,but also the indirect effect through lifestyle on the physiological and the mental health of elderly by social capital is significant. However,the mediation effect is less than the direct effect.
