Value Co-Creation Model for Sustainable Supply Chain: A Case Study of B2B Platforms Empowering SMEs

As the international community enters Digital Upgrade 3.0, small and medium-sized enterprises (SMEs), originally focused on offline business, are exposed to shortcomings such as insufficient capital, monolithic business models, the imbalance between supply and demand, and trust-building behaviors. To address these challenges, this study examines the role of the B2B platform model in facilitating the high-quality development of SMEs. Taking SMEs as the object of study, this study examines the role of the B2B platform model in promoting the high-quality development of enterprises. The impact of sustainable supply chain management and value co-creation theories on SMEs is analyzed by combining theoretical and practical cases. A case study of Alibaba's B2B platform 1688 reveals how the value co-creation model empowered by the platform promotes cooperation and innovation between SMEs and consumers. This study also explores the role of third-party logistics (3PL) in shaping the value co-creation model. Finally, this study provides recommendations for optimizing management models and enhancing collaboration to support the sustainable development of SMEs in the digital era.
