Description
Moving water from the Yangtze River to the Han River helps supply dry areas, but it also mixes water of different quality and spreads pollution duties across regions. Junhua Zhang and co-authors modeled that governance problem in 2026 for the diversion project in China. Players in their model include the central government, the water supply area, polluting firms, and the diversion company, each choosing how hard to work on pollution control.
A two-tier cost-sharing plan, where the center pays part of the cost at two levels, beat both fully separate and fully central decisions in simulations. It raised total pollutant removal by about forty-five percent and total benefits by about thirty percent. The authors offer the design for large water transfer systems.
