Digital Collaboration‑Oriented Supply Chain Management for Fast‑Fashion Enterprises: A Case Study of UNIQLO

In the post-pandemic era, global supply chains have shifted from prioritizing efficiency to placing equal emphasis on efficiency, safety, and resilience. The push-based supply chain model in the fast fashion industry can easily lead to a series of problems, including stockouts and excess inventory, insufficient supply chain resilience, poor cash flow between upstream and downstream sectors, and an amplified bullwhip effect. This paper examines how fast fashion companies can match supply with demand across the chain and enhance chain-wide resilience through optimization of the chain network, digital collaboration, and digital financing. The paper analyses the SPA vertically integrated network of the company, the digitally enabled information-sharing mechanisms and the company's core-enterprise-credit-based "1+N" supply chain finance model by conducting a literature review and analysing one case study of UNIQLO (Fast Retailing Group). The findings show that integrating digital collaboration, network optimization, and supply chain finance enables fast fashion firms to better match supply with demand and build resilience.
