Against the backdrop of frequent adjustments to U.S. tariff policy, the global trade system is undergoing structural reconfiguration, with traditional trade spatial patterns facing profound transformations. From the perspective of trade geography, this paper systematically reviews several frontier topics that merit close attention in the evolution of trade patterns: the geographical reorganization of global value chains, the reshaping of industrial location by regional trade agreements, the spatial effects of digital trade barriers, the resilience assessment of trade networks under geopolitical tensions, and the regionally heterogeneous impacts of tariff policies coupled with environmental sustainability. The paper highlights that enterprises are realigning their production layouts globally, driven by multiple geo-economic factors. At the same time, regional agreements and institutional arrangements significantly influence the logic of value chain construction. Digital barriers are imposing new spatial constraints on information flow and innovation networks, and geopolitical uncertainties exacerbate global trade networks’ fragility. Moreover, the differentiated regional effects of tariff policies may lead to new developmental imbalances, with environmental externalities remaining a critical concern. This paper underscores the vital role of trade geography in the evolving landscape of global governance and advocates for a spatial analytical framework that combines theoretical depth with policy relevance to support the construction of a more resilient, equitable, and sustainable global trade system.
