摘　　要：我国钢铁能源强度与世界先进水平相比存在明显差距。该文比较了我国、日本、韩国三个国家在产值能耗和吨钢能耗两类能源强度指标上的发展趋势,并利用分解分析方法计算了1996-2005年中日韩三国产品及工艺结构和能源效率的变化对各国钢铁吨钢能耗的影响,最后将各国产值能耗与吨钢能耗作进一步比较,并对比较结果进行分析。研究结果表明:能源效率的提升对中国和韩国吨钢平均能耗的下降有重要作用,结构的变化则对日本的吨钢平均能耗的下降有显著影响。因此,产品及工艺结构和效率是影响钢铁能源强度偏高的根本原因,在对产品及工艺结构调整和效率改进的过程中,不仅要注重能耗的降低,还应注重经济性的提高。There is an obvious gap about the energy intensity of China＇ s iron and steel with the woad＇ s advanced level. Tiffs paper compares energy, intensity and specific energy consumption of China, Japan, South Korea, and uses a decomposition analysis to calculate the affects on three countries＇ specific energ） consumption of the changes of products and technology structure and energy efficiency from 1996 to 2005. At last, the paper compared every country’s energy intensity with specific energy consumption, and analyzed the result. The study conclusion showed that products and technology structure and energy efficiency are the root causes for iron and steel energy intensity. In the process of adjusting product and technology structural and improving energy＇ efficiency, we must not only focus on the reduction of energy consumption, but also pay attention to the improvement of the economy.
