基于CGSS2013数据,本文考察了社会资本对个人健康的影响。研究使用了多个主观及客观健康指标以避免测量误差;同时还运用了工具变量、分位数回归、Ranked logit模型等方法控制可能存在的内生性和个体异质性。研究发现社会资本对健康有一定促进作用,但不如预期那么显著。强关系提升了城市居民健康水平,但对农村居民作用不大。弱关系对老年人和农村居民健康水平有促进作用。而社会资本对BMI改善的作用也主要集中在女性和城市样本上。本文证实了社会资本对不同社会群体健康状况的影响存在差异性这一观点,并进一步指出这种差异性还体现在不同类型的社会资本和健康指标上。
Based on CGSS 2013 data, this article examines the impact of social capital on personal health. Several subjective and objective measures of health were used to avoid measurement errors. Tools such as instrument variables, quantile regression, and quarter logistic models were used to control for possible endogeneity and individual heterogeneity. The study found that social capital has some health promotion effect, but not so significant as expected. Strong relationship to improve the health of urban residents, but not for rural residents. Weak relations have a positive effect on the health of the elderly and rural residents. The role of social capital in improving BMI is also mainly concentrated in the sample of women and cities. This article confirms the notion that social capital has different impacts on the health status of different social groups and further points out that this difference is also reflected in different types of social capital and health indicators.
