全球企业网络的社区结构

The Community Structure of the Global Corporate Network

Stefania Vitali, Stefano Battiston

摘要:

我们研究了跨国公司全球所有权网络的社区结构。我们在社区中发现了一种明显的组织,这种组织不能用随机性来解释。尽管这一网络具有全球性质,但社区首先反映了公司的地理位置,而工业部门只起着边缘作用。我们还分析了网络中的节点是社区和链接是通过聚合属于社区对的企业之间的链接。我们分析了前50个社区的网络中心性,并首次对金融业在连接全球经济中的作用进行了定量评估。

英文摘要:

We investigate the community structure of the global ownership network of transnational corporations. We find a pronounced organization in communities that cannot be explained by randomness. Despite the global character of this network, communities reflect first of all the geographical location of firms, while the industrial sector plays only a marginal role. We also analyze the network in which the nodes are the communities and the links are obtained by aggregating the links among firms belonging to pairs of communities. We analyze the network centrality of the top 50 communities and we provide the first quantitative assessment of the financial sector role in connecting the global economy.
