Power in the U.S. political economy: A network analysis
分析了美国大型政治与经济机构之间的所有权、捐赠和交易三类关系网络，发现金融组织在所有权网络中处于核心，政府机构在交易网络中处于核心，而捐赠网络没有明显的核心领域。
Abstract Many features of the U.S. political economy arise from the interactions between large political and economic institutions, and yet we know little about the nature of their interactions and the power distribution between these institutions. In this paper, we present a detailed analysis of networks of U.S.‐based organizations, where edges represent three different kinds of relationships, namely owner–owned (ownerships), donor–donee (donations), and service provider–payee (transactions). Our findings suggest that in the ownerships network, the financial organizations form the core, and banking organizations hold strategic locations in the network. In the transactions network, the government organizations and agencies form the core, and defense‐related organizations form the backbone. In contrast, with the donations network, no specific domain of organizations forms either the core or the backbone.
