| Emission Trading is one of the popular economic measures in the field of environmental management nowadays. Because it makes it possible to accomplish "win-win" strategy: saving economic cost and make environmental effect. After part of developed countries, especially the United States, have been benefit from this kind of measure, more attentions have been paid on its application in developing countries. In combination with a specific issue of SO2 emission cutting in the electric power sector, this paper takes cost-bast economic analysis as the core. More than 2000 power plants in 31 provinces are the target and two scenes of emission cutting, FGD and low sulfur coal, are set where the unit cost of SO2 emission cutting are calculated and the effect of emission trading has been forcasted. What's more, a method of cost-benefit plan of emission cutting for regions and enterprises has been put forward, which is considered as reference for policy makers and researchers. The result indicates that national-wide emission trading is possible to carry out because the difference among the cost of SO2 emission cutting in various areas exists. The compensatory electric price for cost of desulfurization, 1.5 fen/kwh, is a little cheap. In the scenes of FGD and low sulfur coal, the possible range of cost saving is about 34%-45%. According to their own targets of SO2 emission cutting, specific areas or electric power enterprises have opportunity to cut their cost of emission cutting by the way of emission trading and to search for cost-benefit plans to cut SO2 emission, which strives for more development. |
