从1996年到2006年，台湾的二氧化碳排放量增加了约60%，其中工业部门占50%。在所有工业部门中，钢铁、石化、电子、纺织、纸浆和造纸以及水泥约占工业二氧化碳排放总量的四分之三。确定这六个部门二氧化碳排放量增加背后的驱动力可能对制定有效的环境政策很有价值。本文采用双层KLEM投入产出结构分解分析法（I-O SDA）分析了CO2排放变化的影响因素。在台湾的实证结果表明，增加出口水平和提高国内自主最终需求水平的主要原因，CO2排放量的增加。材料和劳动力的技术变革倾向于减少CO2排放，而发电组合对增加贡献显著。还强调了减少能源密集型部门CO2排放的相关战略。
Between 1996 and 2006, CO2emissions in Taiwan increased by approximately 60%, with the industrial sector accounting for 50% of that increase. Among all industrial sectors, iron and steel, petrochemicals, electronics, textiles, pulp and paper and cement accounted for approximately three-quarters of the total industrial CO2emissions. Identifying the driving forces behind increased CO2emissions in these six sectors could be valuable for the development of effective environmental policy. This study used two-tier KLEM input–output structural decomposition analysis (I-O SDA) to analyze the factors that lead to changes in CO2emissions. Empirical results obtained in Taiwan reveal that increased exports level and elevated domestic autonomous final demand level were the main reasons for increases in CO2emissions. Technological changes in materials and labor tended to decrease CO2emissions, while the power generation mix contributed significantly to the increase. Relevant strategies for reducing CO2emissions from energy-intensive sectors are also highlighted.
