With the rapid development of international e-commerce, cross-border e-commerce platforms play a significant role in the global trade supply chain system. However, issues such as complex multi-node collaboration and high transportation costs often lead to an imbalance in inventory distribution and a decline in fulfillment efficiency, thereby restricting the operational benefits and profit margins of platform enterprises. This article mainly focuses on the structural characteristics of the supply chain of cross-border e-commerce platforms and the major problems they are currently facing. It proposes an integration mechanism centered on platform leadership, technology empowerment, and intelligent collaboration, and puts forward cost optimization strategies to provide theoretical references and practical path guidance for cross-border e-commerce platform enterprises.
