Decomposition of SO{sub 2}, NO{sub x} and CO{sub 2} emissions from energy use of major economic sectors in Taiwan
使用Divisia指数法分解台湾1980-1992年主要经济部门SO₂、NOₓ和CO₂排放变化，发现经济增长是最大正向驱动因素，工业部门SO₂排放因燃料质量改善和污染控制而下降，但NOₓ和CO₂排放全面上升。
In this paper we use the Divisia index approach to decompose emission changes of SO{sub 2}, NO, and CO{sub 2} from major economic sectors in Taiwan during 1980 to 1992. The study highlights the interrelationships between energy use and environmental quality, and provides insights for policy making. The emission changes are decomposed into five components-pollution coefficient, fuel mix, energy intensity, economic growth and industrial structure. Of all components analyzed, economic growth had the largest positive effect on emission changes for Taiwan`s major economic sectors. Emissions of SO{sub 2} in industry and other sectors showed a decreasing trend due to fuel quality improvements antipollution control. However, NO, and CO{sub 2} emissions increased sharply in all sectors. Comparisons were also made with Germany, Japan and USA. This study has shown that improvement in energy efficiency, pollution control and fuel substitution are major options to reduce SO{sub 2}, NO, and CO{sub 2} emissions.
