Managing extended supply chains
研究了如何管理超出第一级供应商的延伸供应链，强调低层级供应商的重要性，并提出了采购公司可能采取的管理策略。
Abstract We address how to manage extended supply chains that lie beyond the first‐tier suppliers. The first‐tier suppliers have their suppliers who provide them with goods or services. While lower‐tier suppliers are often not an explicit concern of the focal firm, the firm's performance not only depends on the performance of its first‐tier suppliers, but also on the performance of their suppliers and beyond. These lower‐tier suppliers are much less visible and may not even be known to the focal firm. Our intention is to bring awareness to the importance of these lower‐tier suppliers and capture possible strategies that buying companies may pursue to manage them. Extended supply chains are complex and involve evolving relationships between various buyers and suppliers that are located along different tiers of the chain and across different parts of the globe. We address several topic areas and suggest emerging research focuses that should be considered in coming years.
