借助环境投入产出-生命周期分析,对消费者生活方式方法(Consumer Lifestyle Approach,CLA)进行了改进,进而基于改进后的CLA计算了中国八区域城镇居民的嵌入式碳足迹(Embedded Carbon Footprints,ECF),并采用结构分解分析(SDA)估计了各区域技术和消费模式对ECF的影响。研究发现,技术进步起到了较好的减排作用,但消费模式变化的增排效应强于技术进步的减排效应,进而造成总的ECF增加。基于以上分析,作者认为,仅依靠技术进步来减排是不够的,我国还应把消费领域的节能作为“节能减排”一个重要内容。最后,本文根据不同区域的技术和消费模式对ECF影响的差异,给出了针对性的政策建议。
Based on the environmental input-output-life cycle analysis, Consumer Lifestyle Approach (CLA) was improved, and based on the improved CLA, the embedded carbon footprints of urban residents in eight regions of China were calculated. ECF) and using Structural Decomposition Analysis (SDA) to estimate the impact of regional technology and consumption patterns on ECF. The study found that technological progress played a good role in reducing emissions, but the incremental effect of changes in consumption patterns was stronger than that of technological progress, resulting in an increase in total ECF. Based on the above analysis, the author believes that it is not enough to rely solely on technological progress to reduce emissions. Our country should also regard energy conservation in the consumption area as an important part of “energy saving and emission reduction.” Finally, according to the difference of the influence of technology and consumption patterns in different regions on ECF, this paper gives some suggestions on policy.
