다단계 공급망에서의 소싱 전략 최적화: 위임 소싱 vs. 직접 소싱

초록

This study examines the impact of sourcing strategies and inventory ownership on supply chain performance within a three-tier supply chain consisting of an OEM, a contract manufacturer, and a component supplier. Using a game theory-based model, the study compares delegated and directed sourcing strategies in terms of quality, pricing, and profitability. The findings indicate that directed sourcing leads to higher product quality, which in turn increases consumer demand and enhances overall supply chain profitability. Furthermore, directed sourcing enables firms to maintain higher prices when demand potential is strong, as the benefits of improved quality offset price increases. For OEMs, directed sourcing proves to be a more advantageous strategy when consumer demand is quality-sensitive or when market potential is high, as it ensures better quality control and stronger competitive positioning. Conversely, when cost efficiency is a primary concern due to high inventory costs or price-sensitive consumers, delegated sourcing may be a more viable option. Additionally, while directed sourcing reduces the inventory burden on suppliers, it increases the financial burden on OEMs, highlighting the importance of considering capital accessibility when selecting a sourcing strategy. This study contributes to supply chain management literature by integrating sourcing decisions with inventory cost considerations, providing insights into optimal sourcing strategies under different market conditions. From a managerial perspective, firms must balance cost efficiency with quality differentiation, carefully assessing risk factors and financial constraints when determining sourcing approaches. Future research should incorporate empirical validation and dynamic modeling to further explore the long-term implications of sourcing strategies in multi-tier supply chains.
