The Business Logic of Capital Expansion of Cross-Border E-Commerce under RCEP Framework

《区域全面经济伙伴关系协定》(RCEP)的生效重塑了亚太区域数字贸易格局，而跨境电商作为资本扩张的核心载体，商业逻辑呈现出“制度赋能–效率异化–风险重构”的辩证特征。本文以马克思《资本论》中资本积累理论为分析框架，系统阐释RCEP框架下跨境电商资本扩张的动力机制、效率悖论与治理路径。为数字经济时代全球资本运动的批判性分析提供新的理论视角，亦对区域经济治理具有实践启示。The entry into force of the Regional Comprehensive Economic Partnership (RCEP) has reshaped the digital trade pattern in the Asia-Pacific region, while cross-border e-commerce, as the core carrier of capital expansion, presents the business logic of “institutional empowerment-efficiency alienation-risk reconstruction”. Grounding its analysis in Marx’s theory of capital accumulation from Capitalism, this study systematically examines the driving mechanisms, efficiency paradoxes, and governance pathways of cross-border e-commerce capital expansion under the RCEP framework. It offers a new theoretical lens for the critical analysis of global capital movement in the digital economy era, while also providing practical insights for regional economic governance.
