Research on the Construction Mechanism of Enterprise Flexible Supply Chain Management and Competitive Advantage in Platform Economy

The platform economy uses data connections and rule collaboration to reshape supply chain organizations. Demand fluctuations and external disturbances make traditional chain management slow to respond and resources rigid. This article uses literature review and theoretical analysis to conduct research around enterprise flexible supply chain management and competitive advantage construction under the platform economy. First, define the organizational characteristics of the platform economy, flexible supply chain dimensions and the logic of competitive advantage formation; secondly, analyze demand fluctuations and forecast deviations, cross-subject collaboration and data barriers, platform dependence and risk transmission and other practical constraints; then build a "data perception - resource orchestration - collaborative performance - value feedback" mechanism framework, and propose an implementation path from the aspects of unified and scalable platform architecture, supplier portfolio and flexible operations, risk governance and performance evaluation, etc., and use organizational structure and talent capabilities, platform governance and interest coordination as guarantees. The study believes that the advantage of flexible supply chain is not the result of a single resource or technology, but the linkage effect of demand identification, resource reorganization and ecological synergy. The key is to achieve a dynamic balance between cost, speed, quality and resilience. Enterprises should coordinate platform governance, partner incentives and capability accumulation, and continue to improve the collaborative adaptability of the supply chain.
