论文摘要
在本文中，我们提出了一种适用于全球体现的能量流槽的综合分析的方法。为此，我们扩展了现有文献，根据环境扩展的输入输出分析提供了多层框架。关于传统方法，多层结构使我们能够揭示系统和经济在系统中的不同作用。为了确定关键部门和经济体，我们通过适应我们的框架来扩展Kleinberg算法（称为多维命中（MD-HITS）），利用集线器和权威分数。基于多区域输入输出表的数值分析显示了建议的方法如何提供有意义的见解。
In this paper we propose a methodology suitable for a comprehensive analysis of the global embodied energy flow trough a complex network approach. To this end, we extend the existing literature, providing a multilayer framework based on the environmentally extended input-output analysis. The multilayer structure, with respect to the traditional approach, allows us to unveil the different role of sectors and economies in the system. In order to identify key sectors and economies, we make use of hub and authority scores, by adapting to our framework an extension of the Kleinberg algorithm, called Multi-Dimensional HITS (MD-HITS). A numerical analysis based on multi-region input-output tables shows how the proposed approach provides meaningful insights.
