我国水污染严峻，水质恶化每增加1级，因消化道疾病死亡率增加9.7

China’s rapid industrialization has led to a severe deterioration in water quality in the country’s lakes and rivers. By exploiting variation in pollution across China’s river basins, I estimate
that a deterioration of water quality by a single grade (on a six-grade scale) increases the digestive cancer death rate by 9.7 percent. The analysis rules out other potential explanations such
as smoking rates, dietary patterns, and air pollution. I estimate that doubling China’s levy rates
for wastewater dumping would save roughly 17,000 lives per year but require an additional
500 million dollars in annual spending on wastewater treatment.
