摘要

醫院是一種非營利為主的事業，近年來由於多項醫療政策的實施，使得醫院必須在成本上做有效的控制。醫院的資材存貨成本佔整體醫院的營運成本約31.0%~37.7%，因此如果醫院可以在資材成本上做好管理，可以更有效的節省空間、降低成本。近年來，供應商管理存貨(Vendor-managed inventory, VMI)不斷的被討論，VMI透過資訊分享的方式可以有效降低長鞭效應的發生，也可以降低存貨水準。因此，本研究以交易成本理論與資源依賴觀點探討醫院導入VMI之前因，找出醫院是否願意與供應商資訊分享的影響因素，提升VMI在醫院的使用率。本研究透過問卷郵寄的方式，共寄回收128份有效問卷。問卷資料分析結果顯示，在交易成本理論的部分，資產專用性、交易不確定性、交易頻率是會提升醫院資訊分享的意圖；在資源依賴理論的部分，資源關鍵性、資源替代性亦會提升醫院資訊分享的意圖。而醫院採購人員對VMI系統可以提升存貨管理效率、降低存貨水準都有正向的結果。

Hospital is a non-profit-oriented business. Recently, a number of medical policies have been implemented. Therefore, each hospital must to control their cost. In recent years, VMI(Vendor-managed inventory) has been constantly discussed. VMI can reduce the the occurrence of bullwhip effect through information sharing, and it also can reduce the inventory cost. Therefore, this study combines transaction cost theory with resource dependence theory to explore VMI adoptions in hospital. In this study, a total of 128 valid questionnaires have received. Questionnaire data analysis shows that. In transaction cost theory part, asset specificity, frequency and uncertainty would affect hospital’s information sharing intension. In resource dependence theory part, resource criticality and resource replaceable also affect hospital’s information sharing intension. The results show that hospitals are willing to share their inventory information with suppliers those with commitment relation, also VMI can really inventory levels and affect hospital to manage inventory more efficiency.
