中国工业二氧化硫排放变化指标分解研究

Decomposing Chinese industrial SO_2 emission change index

基于生产理论框架,应用基于Shephard输出距离函数的方法,将我国SO2排放变化指标分解为技术效率影响、技术变化影响、输入增加影响、输出结构影响等5项指标,并对中国28个地区2000~2006年SO2排放变化面板数据进行了实证分析.结果表明：引起我国2000~2006年SO2排放增加的主要因素是工业能源消耗、资本投入及产出结构变化,技术变化则在一定程度上减少了工业SO2排放＂.十五＂期间国家工业SO2排放控制政策,对工业SO2排放控制技术进步及技术效率的提高有明显的促进作用.在区域层面上,东、中、西3个地区的技术变化都促进了工业SO2的减排,其中东部地区由于技术变化所导致的SO2减排较为明显.

This study used a Shephard distance function method,which based on production theoretical framework,to decompose China＇s industrial SO2 emissions change index in 28 different regions during 2000 and 2006.The SO2 emission change index was decomposed to five factors,including technical efficiency change,technical change,inputs growth,and outputs mix.The increasing change of SO2 emission was primarily affected by industrial energy consumption,capital investment,and outputs mix change.Technical change was the only reason to cause industrial SO2 emission declining.The SO2 emission control policies also played an important role in promoting industrial SO2 control technical progress and technical efficiency during the 10th five year plan period.For different areas,the technical progress change in the eastern,central and western China resulted in the reduction of industrial SO2 emission,where the technical change index was a dominant contributor to SO2 emission abatement.
