Abstract：This study analyzed the effect of water pollution control charging policies (wastewater charging system, sewage treatment charging policy and staged water price policy) which were currently implemented in Dianchi Lake basin. And then the performance of water pollution control charging policies of Dianchi Lake basin from 2001 to 2012 were evaluated using the C2R model and BC2 model. The results showed that the policies of wastewater charging system, sewage treatment charging policy and staged water price policy had played important roles for reducing waste water emissions and improving the water using efficiency in the Dianchi Lake basin. The technical efficiency level of water pollution control charging policy in Dianchi Lake basin were high with a mean value of 0.902. The main factor affecting the water pollution control charging policy of Dianchi Lake basin was the industrial added value per unit COD discharge, therefore the government of Dianchi Lake basin could raise the standards of corporate sewage charges or levy discharge taxes in order to reduce pollutants emissions. Adjusting the impose standards of different policies appropriately, as the important environmental economic policies, would help to improve the implementation efficiency level of policies.
