摘要(Abstract)：

可持续消费研究是产业生态学的重要内容。居民消费包括城镇居民消费和农村居民消费。本研究首先采用综合生命周期分析方法(Hybrid LCA)核算1997、2002和2007三年的居民消费隐含的二氧化碳排放总量,发现2007年的碳排放量已经达到18.01亿吨。城镇居民消费已经成为居民消费的主要组成部分,到2007年城镇居民消费的碳排放量达到总量的76.44%。采用结构分解分析(SDA)方法对影响居民消费碳排放量变化的五项驱动因素进行分析,发现排放强度因子是"减缓"居民消费碳排放量增加的主要力量,而人均消费水平因子是推动碳排放量迅速增加的主要因素。同时,发现居民消费结构的变迁对碳排量的增加有一定促进作用。在未来应该通过持续降低能耗强度和加快研发低碳能源技术,来持续降低碳排放强度。另外,要充分挖掘居民生活方式和消费行为的减排潜力,引导消费结构,提倡适度消费,促进居民消费模式向低碳方向转变。
