This case study analysed the global market expansion strategy of a domestic logistics company based on smart digital technology, focusing on Samsung SDS. The logistics industry is shifting from traditional logistics asset-based business models towards building and strengthening IT-based integrated logistics platforms due to accelerated digital transformation. Samsung SDS is a leading domestic company that has responded to these changes by establishing a Fourth Party Logistics (4PL) model. This study, based on the SER-M model, integrated a temporal dimension to analyse the dynamic evolution of its growth strategy in particular. From its full-scale entry into logistics in 2012 to the present day and looking ahead to 2025, Samsung SDS's strategy has evolved through three distinct phases: the “Logistics BPO (Business Process Outsourcing) Entry and Overseas Hub Establishment Phase”, the “Platform Solution Development and Overseas Business Expansion Phase”, and the “Cello Square-Centered Open Global Expansion Phase”. Analysis confirmed that the strategic choices and resource allocation mechanisms of the entity dynamically operated in response to environmental changes at each stage. These findings provide insights into the strategic elements required for digitally-based, non-asset logistics companies to secure global competitiveness, as well as the digital capability development and environmental response approaches for late-entrant logistics companies.
