摘要：

This article estimates the effect of industrial water pollution on agricultural productivity and its further consequences on labor reallocation in China, using a spatial design that exploits a high-resolution hydrological network. We show that industrial wastewater discharged within 150 km upstream significantly increases local water pollution and reduces crop productivity. The negative externality is mainly caused by firms in the highly polluting industries, and the pollution-induced productivity shock is magnified if the local village is closer to the river, has lower groundwater availability, and receives less precipitation. Rural households increasingly engage in non-farm work and migration in response to the environmental shock. Further quantification indicates substantial overall costs on food production and highly distributional effects on labor reallocation.
