能源消耗一直是可持续城市评估和规划的核心问题。不同形式的能源分析可以为能源政策制定提供各种见解。本文汇集了三种能源消费核算方法，即，能流分析（EFA）、投入产出分析（IOA）和生态网络分析（ENA），并比较了它们的不同观点及其对城市能源利用的政策含义。以北京为例，说明了不同的能源分析流程，并将该市的42个经济部门汇总为7个组成部分。已确定的是，全民教育通过跟踪城市经济使用的不同类型的燃料，对城市组成部分的初级和最终能源消费进行量化。IOA占体现能源消耗（直接和间接）用于生产商品和服务的城市，而ENA的控制分析量化的具体体现能源，是由城市的边界内的活动。网络控制分析还可以应用于确定哪些经济部门驱动能源消耗以及这些部门在能源方面相互依赖的程度。所谓“可控能源”是城市能源消费分析中的一个新概念，指的是各部门可调节的能源消费。从所有三个会计角度的见解的整合进一步我们对城市可持续能源利用的理解。(C)2014爱思唯尔有限公司版权所有。
Energy consumption has always been a central issue for sustainable urban assessment and planning. Different forms of energy analysis can provide various insights for energy policy making. This paper brought together three approaches for energy consumption accounting, i.e., energy flow analysis (EFA), input-output analysis (IOA) and ecological network analysis (ENA), and compared their different perspectives and the policy implications for urban energy use. Beijing was used to exemplify the different energy analysis processes, and the 42 economic sectors of the city were aggregated into seven components. It was determined that EFA quantifies both the primary and final energy consumption of the urban components by tracking the different types of fuel used by the urban economy. IOA accounts for the embodied energy consumption (direct and indirect) used to produce goods and services in the city, whereas the control analysis of ENA quantifies the specific embodied energy that is regulated by the activities within the city's boundary. The network control analysis can also be applied to determining which economic sectors drive the energy consumption and to what extent these sectors are dependent on each other for energy. So-called "controlled energy" is a new concept that adds to the analysis of urban energy consumption, indicating the adjustable energy consumed by sectors. The integration of insights from all three accounting perspectives further our understanding of sustainable energy use in cities. (C) 2014 Elsevier Ltd. All rights reserved.
