This study analyzes the current research status and existing issues in logistics cost management among domestic and international enterprises, summarizing the composition and influencing factors of logistics costs. Leveraging the foundation of “Internet plus,” this research conducts an analysis and study on enterprise logistics costs by optimizing the supply chain model for Company YX. It proposes optimized supply chain logistics models based on activity-based cost indicators and joint distribution, designing four optimization strategies: logistics cost control at nodes, optimized transportation routes, management pathways, and supply chain coordination. The optimization and implementation focus on logistics transportation routes. This provides a reference for other enterprises in managing logistics costs.
