Research on JD Logistics Cost Management under the Background of Digital Economy

数字经济背景下，自营式电商平台的发展，越来越倚重智能化和个性化，所以需要企业提供更高效、更精准的服务。本研究将京东物流当作研究对象，通过整合价值链理论和层次分析法(AHP)来剖析物流成本管理的关键难题与突围策略，给行业提供优化框架。通过构建起内外部价值链协同的层次分析模型，用专家问卷法对采购、仓储、供应商等环节的权重分布加以量化，并且将一致性检验和横向对比相结合，以此来揭示出京东物流现在面临的核心问题，从而为自营式电商企业在成本控制和服务品质之间达成平衡提供理论依据。In the context of the digital economy, the development of self-operated e-commerce platforms increasingly relies on intelligence and personalization, which requires enterprises to provide more efficient and accurate services. This study takes JD Logistics as the research object, integrates value chain theory and Analytic Hierarchy Process (AHP) to analyze the key issues and breakthrough strategies of logistics cost management, and provides an optimization framework for the industry. By constructing a hierarchical analysis model for internal and external value chain collaboration, using expert questionnaire method to quantify the weight distribution of procurement, warehousing, suppliers and other links, and combining consistency testing and horizontal comparison to reveal the current core problems of JD Logistics, this provides a theoretical basis for self-operated e-commerce enterprises to balance cost control and service quality.
