摘 要: | In this study, reduction in sulfur dioxide (SO2) emission is decomposed into three parts: source preven- tion, process control and end-of-pipe treatment, using the Logarithmic Mean Divisia Index method (LMDI). Source prevention and process control are defined as process- integrated treatment. It is found that from 2001 to 2010 the reduction of SO2 emission density in China was mainly contributed by end-of-pipe treatment. From the 10th Five Year Plan (FYP) period (2001-2005) to the llth FYP period (2006-2010), the Chinese government has attempted to enhance process-integrated treatment. How- ever, given its initial effort, the effect is limited compared with that of the end-of-pipe treatment. The effectiveness of environmental regulation and technology in the reduction of SO2 density in 30 provinces (municipality/autonomous regions) from 2001 to 2010 is also investigated. This implies that environmental regulation and technology promote process control and end-of-pipe treatment sig- nificantly, but does not influence source prevention. Furthermore, environmental technology will only take effect under the circumstances of stringent environmental regulation. Therefore, to fulfill the whole process treat- ment, environmental regulation should be strengthened and environmental technology upgraded at the same time.
