This paper combines differences-in-differences with propensity score matching to estimate the impacts of a health reform project in China that combined supply-side interventions aimed at improving the effectiveness and quality of care with demand-side measures aimed at expanding health insurance and providing financial support to the very poor. Data from household, village and facility surveys suggest the project reduced out-of-pocket spending, and the incidence of catastrophic spending and impoverishment through health expenses. Little impact is detected on the use of services, and while the evidence points to the project reducing sickness days, the evidence on health outcomes is mixed.
本文将双重差分法与倾向得分匹配法相结合，以评估中国一项医疗改革项目的影响。该项目结合了旨在提高医疗服务有效性和质量的供给侧干预措施，以及旨在扩大医疗保险覆盖范围并为极贫困人口提供财政支持的需求侧措施。来自家庭、村庄和医疗机构调查的数据表明，该项目降低了自付费用，以及因医疗费用导致的灾难性支出和贫困发生率。未发现该项目对服务利用有显著影响，虽然有证据表明该项目减少了患病天数，但关于健康结果的证据好坏参半。
