This paper investigates the effect of a major water quality improvement program in rural China on the health of adults and children. Using panel data covering about 4500 households from 1989 to 2006, I estimate the impact of introducing village-level access to water from water plants on various measures of health. The regression results imply that the illness incidence of adults decreased by 11 percent and their weight-for-height increased by 0.835kg/m, and that children's weight-for-height and height itself both rose by 0.446kg/m and 0.962cm respectively, as a result of the program. And these estimates are quite stable across different robustness checks.
本文研究了中国农村一项重大水质改善计划对成年人和儿童健康的影响。利用 1989 年至 2006 年期间涵盖约 4500 户家庭的面板数据，本文估计了在村级引入水厂供水对各种健康指标的影响。回归结果表明，该计划使成年人的发病率降低了 11%，体重身高比增加了 0.835kg/m，儿童的体重身高比和身高分别增加了 0.446kg/m 和 0.962cm。这些估计在不同的稳健性检验中都相当稳定。
