城市能源代谢包括能源的开发、转化和消费过程，以及副产品和废物的回收过程。消耗的能量是在所有这些活动中直接和间接消耗的能量。多区域投入产出（MRIO）分析可以计算多个城市或地区的部门间流动所体现的能源消耗。我们的目标是解决以前研究中存在的一个问题，即对间接能源流动的关注不够。我们将MRIO分析与生态网络分析相结合，使用2002年和2007年的数据，计算了京津冀三个地区五个部门的隐含能源消费和能源相关碳足迹。我们的分析从最终消费的角度追踪了部门的代谢过程。基于体现能分析，量化了部门间交易所隐含的间接能源消耗及其分布，并识别了间接能源消耗所形成的关系，分析了系统中供应者和接受者的角色。结果表明，2002年至2007年，京津冀地区的隐含能源消费增加，天津和河北的能源消费增加的结果。整体而言，北京的消费下降可能是由于政府政策在此期间转移产业以迎接奥运会。行业之间的关系发生了变化：北京从净出口国转变为进口国，河北从北京的能源净进口国转变为北京的能源出口国，天津在这两年都是进口国。
Urban energy metabolism includes processes for exploiting, transforming, and consuming energy, as well as processes for recycling by‐products and wastes. Embodied energy is the energy consumed during all of these activities, both directly and indirectly. Multiregional input‐output (MRIO) analysis can calculate the energy consumption embodied in flows among sectors for multiple cities or regions. Our goal was to address a problem apparent in previous research, which was insufficient attention to indirect energy flows. We combined MRIO analysis with ecological network analysis to calculate the embodied energy consumption and the energy‐related carbon footprints of five sectors in three regions that comprise the Jing‐Jin‐Ji agglomeration, using data from 2002 and 2007. Our analysis traced metabolic processes of sectors from the perspective of final consumption. Based on the embodied energy analysis, we quantified the indirect energy consumption implied in exchanges of sectors and its distribution and identified the relationships formed through the indirect consumption to analyze the roles of providers and receivers in the system. Results showed that the embodied energy consumption for the Jing‐Jin‐Ji region increased from 2002 to 2007 as a result of increased energy consumption in Tianjin and Hebei. Overall, consumption of Beijing decreased likely attributable to the fact that government policies relocated industries during this time in anticipation of the Olympic Games. The relationships among sectors changed: Beijing changed from a net exporter to an importer, whereas Hebei changed from a net importer of energy from Beijing to an exporter to Beijing, and Tianjin served as an importer in both years.
