About the Seminar
We set up a bilevel programming model for control of SO2 emissions by the tax mechanism. We discuss the existence of the model solution, prove the effectiveness of emission tax mechanism, and use the data from 2001-2010 of China to test the model and mechanism empirically. Our results show that emission tax mechanism could regulate the system towards the centralized optimization goals. We show that when emission tax rate increases, the SO2 emission rates in mining and power generation, and gas and water production and supply will decline while that of manufacturing will increase; at the same time, the pollution treatment cost in manufacturing will decrease while those of mining and power generation, and gas and water production and supply will rise compared with them current value. Because of bearing the pollution costs and also paying higher emission tax, it will impact not only the development of enterprises themselves but also the pricing system of national economy. Therefore, a reasonable redistribution of the tax revenue should be made together with emission tax mechanism.
