摘 要 ：1992年联合国提出可持续消费的概念，经过10几年的发展，生命周期分析已经成为可持续消费的主要研究方法。由于传统生命周期分析方法需要大量基础数据支持，因此目前综合生命周期分析方法被广泛应用于可持续消费研究中。以1997年中国投入产出表为基础，建立了包括CO2排放量的投入产出表延长表。并对居民终端消费产生的CO2排放总量及其与产业部门的关系进行了分析。结果表明，1997年城市居民终端消费人均CO2排放量为1576.62kg，是农村居民CO2排放量的24.96倍，城市居民每个单位货币消费量所产生的CO2的排放量也远远高于农村居民，电力生产部门对居民消费环境影响的贡献率最大。对该方法中存在的一些问题进行了讨论，这些问题主要产生在价值量与物理量转换过程及分配过程中。

Abstract:In 1992, the United Nations brought forward the concept of sustainable consumption and called for life cycle thinking as an important approach in promoting sustainable consumption. After more than 10 years development, life cycle analysis (LCA) has been accepted as the main method in sustainable consumption research. To overcome the limition of traditional LCA, hybrid LCA, which is a method that combine economic input-output analysis and traditional LCA is now widely used in sustainable consumption research. In this paper, we use an example to explain the method of hybrid LCA and its usages in sustainable consumption research. We first established an extended Chinese input-output table with CO2 emission. Then we analyzed the CO2 emissions of final consumption and their interaction with industrial sectors. Our calculations showed that in 1997, per capita CO2 emission from urban households were 1576.62kg, 24.96 times higher than rural households. The electricity production and supply sector is the main CO2 emission contributor to final consumption. Uncertainties in using hybrid LCA were reviewed.
