摘要|Abstract
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 over 50 billion cubic meters 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.
