中国居民家庭脆弱性及因病致贫效应分析

Analysis on Household's Vulnerability and Effect of Catastrophic Health Expenditures on Poverty in China

为定量分析医疗支出对家庭经济水平的冲击,以贫困脆弱性指标作为家庭经济风险的代理变量,利用微观调查数据构造反事实框架估计就医行为对家庭经济境遇的冲击,验证了医疗与家庭致贫效应的因果关系和影响程度。家庭成员在过去半年内若因病住院,对家庭福利会造成损失,损失幅度因贫困标准、样本年份而不同。2012年在贫困线标准为2美元条件下,家庭经济风险概率值增加0.31。分城乡和收入高低不同组估计,农村居民以及低收入群体的福利水平受就医影响幅度大于对应的其他群体。
