Abstract:

CostBenefit analysis is applied in our research to evaluate the performance of emission reduction policies in Guizhou Province,one of acid rain severely afflicted areas in China,during 11th FiveYear Plan period.The results from our research indicate:1) After the implementation of the 11th FiveYear SO2 reduction policies,the air quality of Guizhou Province is remarkable improved,the acidity and frequency of the acid rain are reduced significantly,and especially some frequency of acid rain in some cities has been reduced to zero.2) The cost of reduction is about 228 billion RMB,and the benefit of reduction is 27 billion RMB.The net gain of SO2 reduction policies in Guizhou Province is positive and the advantage effects of pollution reduction binding targets are emerging,such as the efficiency of energy utilization is improved and the economic structure is optimized.3) Installation rate of desulfurization in thermal power generation plant has reached more than 90%.It indicates that the potential of SO2 reduction contributed by engineering projects is limited.Thus,to achieve air pollution reduction binding targets,Guizhou Province needs to pay more attention to structural emission reduction and emission management
