摘要本文提出了一种基于产品寿命累积分布的结构分解分析方法，以估计产品寿命变化和能源效率变化对隐含能源消耗的影响。实证分析的重点是1990-2000年期间日本的汽车使用（普通客车、小型客车和轻型客车）。结果表明，在研究期间延长现有旧车的使用寿命比购买燃油经济性相对较高的新乘用车对环境更有利，因为延长使用寿命在经验上有助于降低生产和最终使用阶段的体现能源消耗。我们还发现，寿命延长一年的节能效果大约是发电部门最重要的技术改进的1.3倍。在此基础上，作者在伊斯坦布尔举行的第16届国际投入产出大会上获得了第三届Leontief纪念奖。他们获得了这个奖项，这是由泰勒和弗朗西斯，为最佳会议论文的作者年龄在40岁以下。
Abstract The presenft paper develops a structural decomposition analysis with cumulative product lifetime distributions to estimate the effects of both product lifetime shifts and energy efficiency changes on the embodied energy consumptions. The empirical analysis focuses on automobile use (ordinary passenger vehicles, small passenger vehicles, and light passenger vehicles) in Japan during the period 1990–2000. It reveals that the lifetime extension of existing old vehicles during the study period was more beneficial to the environment than purchasing new passenger vehicles with a relatively high fuel economy, because the lifetime extension empirically contributed to reducing the embodied energy consumption at the production and end-use stages. We also found that the energy-saving impact of a one-year lifetime extension was approximately 1.3 times larger than that of the most significant technological improvement in the electric power generation sector. Editor's NoteOn the basis of this paper, the authors were awarded the third Leontief Memorial Prize at the 16th International Input–Output Conference in Istanbul. They received this prize, which is sponsored by Taylor & Francis, for the best conference paper by authors younger than 40 years.
