As the largest and the most expensive inter-basin water transfer project in the world, the Chinese South-North Water Transfer (SNWT) project has diverted 50 billion cube meter of water from the Yangtze river to Northern China, which raised extensive debates. In this paper, we attempt to justify the SNWT by providing ex-post evidence on the causal effects of the project on public health. We rely on the natural experiment of the middle route to implement a spatial Regression Discontinuity Design (RDD) with the longitudinal survey data of the Chinese Family Panel Studies (CFPS). The RDD estimates suggest that the SNWT reduced health expenditure of affected residents by at least 54%, which is primarily due to the reduced waterborne diseases, cancers and hospitalization for residents in Northern China. The effects are more pronounced for residents live in urban area, arid area and for those with access to tap water. The robust results provide a scientific base for the cost-benefits analysis of water infrastructure in arid and semi-arid areas.

作为世界上规模最大、造价最高的跨流域调水工程,中国南水北调工程将500亿立方米长江水调入北方,引发了广泛的争论。本文试图通过项目对公共健康的因果影响来证明南水北调工程的合理性。利用中国家庭追踪调查(CFPS)的面板数据,通过中间路线的自然实验,进行空间回归间断设计(RDD)。RDD估计表明,南水北调工程使受影响居民的卫生支出至少减少了54%,这主要是由于中国北方居民减少了水传播疾病、癌症和住院治疗。这种影响对居住在城市地区、干旱地区和有自来水的居民更为明显。研究结果为干旱半干旱地区水利基础设施的成本效益分析提供了科学依据。
