With the development of global logistical systems to coordinate the movement of goods, cities around the world are being reconceived as nodes in circuits of commodity capital. These efforts are reshaping urban environments and provoking novel forms of political resistance. They are also bringing distant places and subjects into new relations of interaction and interdependence. This article traces the web of urban change and contestation that has taken shape around the expansion of the Panama Canal, an infrastructure megaproject with reverberations that have been felt in port cities throughout the Americas. Drawing on research conducted in the Panama City, Los Angeles, and New York City areas, I examine efforts to remake urban space in the name of smooth, efficient circulation—what I call supply-chain urbanism—and the struggles that have ensued over land, labor, and environments. The concept of supply-chain urbanism calls attention to the life-damaging impacts of goods movement on communities and workers, impacts that are unevenly distributed across space, race, and class. Crucially, it also underscores the connections between seemingly disparate episodes of urban change and resistance. Beyond shedding light on emerging forms of logistics-based urbanization, the article illustrates the value of relational methodologies for the study of networked urban dynamics. In disclosing the wider forces, processes, and flows that connect far-flung experiences of urban transformation and struggle, such approaches can apprehend the interlinked character of contemporary urbanization processes in ways that purely local perspectives cannot.

随着协调货物流动的全球物流系统的发展，世界各地的城市正在被重新设想为商品资本循环中的节点。这些努力正在重塑城市环境并引发新形式的政治抵抗。它们还将遥远的地方和主题带入了新的互动和相互依存关系中。本文追溯了围绕巴拿马运河扩建形成的城市变化和竞争网络，巴拿马运河是一个基础设施大型项目，在整个美洲的港口城市都感受到了影响。借鉴在巴拿马城、洛杉矶和纽约市地区进行的研究，我研究了以平滑、有效流通——我称之为供应链城市化——以及随之而来的土地、劳动力和环境斗争。供应链城市化的概念提请关注货物流动对社区和工人的生命破坏影响，这些影响在空间、种族和阶级中分布不均。至关重要的是，它还强调了看似截然不同的城市变化与抵抗之间的联系。除了阐明以物流为基础的城市化的新兴形式之外，本文还说明了关系方法论对研究网络化城市动态的价值。在揭示将城市转型和斗争的广泛经验联系起来的更广泛的力量、过程和流动时，
