英文摘要:
Quantifying the importance and power of individual nodes depending on their position in socio-economic networks constitutes a problem across a variety of applications. Examples include the reach of individuals in (online) social networks, the importance of individual banks or loans in financial networks, the relevance of individual companies in supply networks, and the role of traffic hubs in transport networks. Which features characterize the importance of a node in a trade network during the emergence of a globalized, connected market? Here we analyze a model that maps the evolution of trade networks to a percolation problem. In particular, we focus on the influence of topological features of the node within the trade network. Our results reveal that an advantageous position with respect to different length scales determines the success of a node at different stages of globalization and depending on the speed of globalization.

中文摘要:
根据各个节点在社会经济网络中的位置,量化各个节点的重要性和影响力,这在各种应用中都是一个问题。例如,个人在(在线)社交网络中的影响力、个人银行或贷款在金融网络中的重要性、个别公司在供应网络中的相关性以及交通枢纽在交通网络中的作用。在全球化、互联市场出现期间,贸易网络中节点的重要性体现在哪些特征上?在这里,我们分析了一个模型,该模型将贸易网络的演化映射为一个渗流问题。特别地,我们关注贸易网络中节点拓扑特征的影响。我们的结果表明,不同长度尺度的优势地位决定了节点在全球化不同阶段的成功与否,这取决于全球化的速度。
