摘要
本文利用中国健康与养老追踪调查四期数据(CHARLS 2011-2018),以村庄中老年群体为参照对象,实证检验农村中老年人的健康同群效应及其作用机制。研究结果表明,在我国农村地区,中老年群体存在显著的健康同群效应,本村中老年群体的健康水平越高,个体的健康状况越好。采取不同健康衡量指标、构建虚拟同群、寻找工具变量进行参数估计,结果依然稳健。从群体特征来看,健康的同群效应更为显著地发生在女性、文盲和低收入的农村中老年群体,信息获取能力和行为决策水平的差异是同群效应发挥作用的条件。通过考察本村中老年人吸烟、饮酒、健身和参与医疗保险等行为表现,本文证实健康行为在群体内存在显著的示范效应,进而合理解释了健康同群效应的作用机制。本文的研究结论对制定中老年群体健康干预政策以及推进中国健康老龄化战略的实施具有重要的现实意义。
This study examines peer effects on the the middle-aged and older people's health status and its mechanism based on the data of 4 surveys of the China Health and Retirement Longitudinal Study from 2004 to 2011 by individual fixed effects methods.The finding show there is a significant peer effects on the health of the middle-aged and older adults,and the more health status of the older people in the village,the more health the individual is.This conclusion is keep robust by varied self-rated health measurement and the construction of virtual peers group,and the parameter estimation of instrumental variables.The peer effects is more significant among the females,the illiterate and low-income middle-aged and older adults and the ability of information acquisition and decisionmaking is the main mechanism of peer effect.This peer effect and its mechanism are further explained by the demonstration effect in the health and risky behaviors of the villagers such as smoking,alcohol drinking,fitness,and medical insurance decisions.
