Inter-relationships among strategic purchasing buyer-seller relationship and logistics integration

[[abstract]]摘要 快速變化的商業環境下，企業與企業間以價格為導向的競爭，已經逐漸轉變為供應鏈與供應鏈間以速度為決勝點的競爭。企業的「採購」單位屬於前端體系，主要掌管產品的交易、追求最低的整體成本與最好的服務品質。主動及有效率的採購組織，能夠整合跨部門需求，進而運用供應商資源提昇供應管理的效率與效能。至於「物流」單位則負責產品在流通過程中所發生的相關作業、流程及活動，沒有流通的物流體系將會癱瘓供應鏈的運作。過去多數的研究多單獨探討採購或物流架構下的作業流程，而探討採購與物流間交叉關係的研究則不多。 本研究以結構方程模式對策略性採購、買賣關係及物流整合進行探討，研究這三個構面下彼此間是否存在正向影響。研究結果顯示，這三個主構面彼此間是正向地相互影響著，其中又以策略性採購的次要構面-聚焦，牽動著三個主構面間的關係，同時也是影響供應鏈活動的主要競爭因素。此研究結果可以提供給採購管理者及物流管理者一些參考，亦即明確長期的規劃及發展方向，能使得供應鏈之成員間相互信任彼此依賴，並進而透過良好的買賣關係來鞏固買賣雙方彼此的重要性，最終能夠提昇供應鏈中物流領域的整合價值，強化企業在供應鏈體系下的競爭力。[[abstract]]Abstract Under fast-changing business competitive environment, price-based competition between enterprises has been replaced by time-based competition between supply chains. Purchasing function plays a pioneering role in an enterprise, which is responsible for product transactions, cost control, and service quality. A proactive and efficient purchasing organization can make cross-functional integration easier. In contrast, logistics function takes the responsibility of physical transportation and warehousing activities, operations, and processes from vendors to factories. Without good supports from logistics, supply chain cannot work seamlessly. Most past researches focused only on either function. Researches focusing on the interaction of these two functions are lack of investigation. Structural equation model (SEM) is applied in this research to examine inter-relationships among strategic purchasing, buyer-seller relationships, and logistics integration. The results indicate that positive impacts among these three dimensions exist. Among individual factors, “focusing” under “strategic purchasing” dimension is the key factor for making supply chain integration successful. This implies that focusing on long-term development of purchasing strategy will have positive impact on buyer-seller relationship, which in turn affects logistics integration
