世界投入产出网络
World Input-Output Network
摘要：
传统上被分析为几乎独立的国家系统的经济系统在全球范围内的联系日益紧密。世界投入产出数据库是最近才建立的，它是在全球一级编制多区域投入产出表的第一批努力之一。通过将世界投入产出系统视为一个相互依赖的网络，其中节点是不同经济体中的各个行业，边缘是行业之间的货币商品流动，我们研究了所谓的世界投入产出网络（WION）的网络特性，并记录了其随时间的演变。我们能够量化不仅是一些全球网络的属性，如迁移率，聚类系数，度和强度分布，但它的子图结构和动态使用社区检测技术。随着时间的推移，我们发现生产系统的跨国连通性显著增加，只是被2008-2009年的危机暂时中断。此外，我们还发现，以德国为首的欧洲投入产出区域共同体正在不断壮大，中国在全球生产体系中的地位也在上升。最后，我们使用基于网络的PageRank中心度和社区核心度来识别WION中的关键行业和经济体，其结果不同于传统的最终需求加权后向联系度量。
英文摘要：
Economic systems, traditionally analyzed as almost independent national systems, are increasingly connected on a global scale. Only recently becoming available, the World Input-Output Database (WIOD) is one of the first efforts to construct the multi-regional input-output (MRIO) tables at the global level. By viewing the world input-output system as an interdependent network where the nodes are the individual industries in different economies and the edges are the monetary goods flows between industries, we study the network properties of the so-called world input-output network (WION) and document its evolution over time. We are able to quantify not only some global network properties such as assortativity, clustering coefficient, and degree and strength distributions, but also its subgraph structure and dynamics by using community detection techniques. Over time, we detect a marked increase in cross-country connectivity of the production system, only temporarily interrupted by the 2008-2009 crisis. Moreover, we find a growing input-output regional community in Europe led by Germany and the rise of China in the global production system. Finally, we use the network-based PageRank centrality and community coreness measure to identify the key industries and economies in the WION and the results are different from the one obtained by the traditional final-demand-weighted backward linkage measure.
