标题： The Topology of Inter-industry Relations from the Portuguese National Accounts

摘要： 在近几年，葡萄牙经济经历了一个严重的调整过程，影响了几乎所有工业部门，这些部门是经济结构的基石。 关于经济结构变化的研究利用了投入产出表来定义工业关系的网络。 在这里，这些网络是从葡萄牙国家会计系统的产出表中推导出来的，每个产业间的关系由任何两个产业为其共同生产的产品所做出的产出来定义。 对这些网络的拓扑分析能够揭示出在葡萄牙调整计划期间出现的一种特定结构。 工业网络的演变显示在2011-2014年间发生了重要的结构性变化，证实了从产出表中推导相似性网络的有用性，以及随后图形式在产业间关系分析中的潜在优势。 显示英文摘要

摘要： In last years, the Portuguese economy has gone through a severe adjustment process, affecting almost all industrial sectors, the building blocks of economic structures. Research on economic structural changes has made use of input/output tables to define networks of industrial relations. Here, these networks are induced from output tables of the Portuguese national accounting system, being each inter-industry relation defined by the output made by any two industries for the products that they both produce. The topological analysis of these networks allows to uncover a particular structure that comes out during the Portuguese adjustment program. The evolution of the industrial networks shows an important structural change in 2011-2014, confirming the usefulness of inducting similarity networks from output tables and the consequent promising power of the graph formulation for the analysis of inter-industry relations.
