摘要:Two taxation schemes were designed to be included in a multi-regional multi-sectoralGeneral Equilibrium model for reducing the use of commercial fertilizers, with the goal ofalleviating surface water pollution. Under the 500% tax rate, results showed that 0.1% of thenational income was given up in order to exchange for a 3% reduction in the fertilizer applicationused as an intermediate input. Furthermore environmental quality would be improved by 3%, if alinear relationship existed between the changes in intermediate fertilizer use and the improvementin environmental quality.
