完全隐含能源与碳强度研究进展综述

Reviews of Studies on Aggregate Embodied Energy and Carbon Emission Intensities

节能减排是应对全球气候变暖的重要举措。由于不同国家和地区的经济发展水平存在明显差异,近年来能源与碳强度成为度量节能减排绩效的重要指标,受到了社会各界的广泛关注。在生产端强度控制的基础上,如何从根源上在消费端降低完全隐含能源与碳强度的研究越来越受到重视。针对消费端完全隐含能源与碳强度的研究特征与发展趋势展开综述,结果发现:(1)主要呈现出国家层面研究为主、全球层面研究显著增加、省市层面研究开始出现的特征,且国家或省市层面主要聚焦于中国;(2)相比完全隐含能源强度,现有文献更为关注完全隐含碳强度;(3)研究由不区分终端消费向细分各终端消费发展,隐含在出口中的完全隐含碳强度受到了重点讨论;(4)部分研究侧重于局部,比如深度参与到全球生产网络的部分经济部门或能源消费与碳排放在生产网络中传输的关键层级;(5)进行完全隐含碳强度变动的驱动因素的研究主要基于乘性结构分解分析模型,从时间轴和空间轴展开剖析。现有研究框架未来可以扩展到能源环境相关领域的其他指标。

Energy saving and carbon reduction are crucial to global climate change mitigation.As the economic developments of countries and regions are of great difference,energy and emission intensities,which have drawn wide public attention,become significant indexes to measure energy saving and carbon reduction.On the basis of production-side intensity control,how to fundamentally curb the aggregate embodied energy and emission intensities from the consumption side has attracted increasing attention.Thus,this study conducted a literature review on consumption-side intensities.It is found that:(1)Studies at national level are dominating,those at global level increase significantly,and those at provincial and city levels have begun to emerge.In particular,the studies at national,provincial,and city levels are chiefly about China.(2)Compared with aggregate embodied energy intensity,aggregate embodied emission intensity has received greater attention.(3)Existing studies on consumption-side intensities extend from indistinguishable final demands to distinguishable final demands,while those embodied in exports attract hot discussions.(4)Some scholars focus on local areas,such as economic sectors which heavily participate in global production networks,as well as the critical transmission layers of energy consumption and carbon emissions within the production network.(5)The temporal and spatial determinants of consumption-side intensities are measured by multiplicative structural decomposition analysis.The current framework can be extended to other indicators related to energy and environmental fields in the future.
