| 摘 要： | 随着居民生活水平的提高和生活方式的转变，居民消费所产生的温室气体排放引起越来越多的关注.利用环境投入产出生命周期分析方法（EIO-LCA），基于中国2007年投入产出表，核算了中国省域层次城乡居民消费所产生的直接和间接碳排放.研究结果表明：1）省域层次居民消费的碳足迹，总体呈现从东南沿海向西北内陆逐渐递减的趋势；2）各省域城镇居民消费的碳足迹明显高于农村居民，其中城镇居民消费的间接碳排放是居民消费碳足迹中主要贡献因子；3）省域之间人均消费碳足迹城乡差距较大，省市的经济发展水平越高，其城乡人均间接碳排放差异越小.

| Abstract: | With the development of household living standards, the increasing carbon emission of household consumption has gradually turned into one of the hot research subjects in recent years. In this paper, the carbon footprints of urban and rural household consumption in China's 30 province-level regions are calculated based on the economic input-output life cycle analysis method. The results are described in the following aspects. In the aspect of total quantity, the general trend of the household carbon footprint in the 30 province-level regions gradually decreased from the southeast coastal regions to the northwest inland. Meanwhile, the urban household consumption is significantly higher than that of the rural residents. In the other aspect of the per capita household carbon footprint, it is noteworthy that the gap which increases with proportion of the urban per capita indirect carbon emission shows a trend of increase in the higher economic level of province-level regions. |
