摘要：We investigate the agricultural and economic impacts of China’s South-North Water Diversion Project, a massive initiative that channels water from the abundant southern regions to the drier north. Using a difference-in-differences approach, we find the project leads to an 8.2% increase in total grain output and a 4.7% boost in agricultural productivity for water-receiving counties. Additionally, the project mitigates the adverse effects of drought shocks, resulting in modest increases in local incomes. We find no evidence that areas providing water experience significant losses. Back-of-the-envelope calculations indicate an internal rate of return of 6.4%, highlighting the project’s economic viability.
