论文摘要
国际贸易网络是一个复杂的系统，在该系统中，多个大小不同的贸易集团共存并彼此重叠。但是，贸易网络中社区发现的结构通常是不一致的，并且无法捕捉国际贸易的复杂景观。为了解决这些问题，我们提出了一个多分辨率框架，该框架汇总了一系列分辨率的所有配置信息。这使我们能够考虑具有不同规模的贸易社区，并阐明贸易网络及其构成区块的基本层次结构。此外，通过衡量每个国家的成员不一致（MEI）并使用各种经济和政治指标进行多重回归分析，我们证明了国家的外部不稳定与网络拓扑之间的结构不一致之间存在正相关。
The international trade network is a complex system where multiple trade blocs with varying sizes coexist and overlap with each other. However, the resulting structures of community detection in trade networks are often inconsistent and fails to capture the complex landscape of international trade. To address these problems, we propose a multiresolution framework that aggregates all the configuration information from a range of resolutions. This allows us to consider trade communities of different sizes and illuminate the underlying hierarchical structure of trade networks and its constituting blocks. Furthermore, by measuring membership inconsistency (MeI) of each country and conducting multiple regression analysis with various economic and political indicators, we demonstrate that there exists a positive correlation between the external instability of countries and their structural inconsistency in terms of network topology.
