本研究以Williamson(1975)之交易成本理論為基礎，探討製造商與專業物流業者間交易特性、交易成本及夥伴關係之關聯性。研究結果發現企業投入專屬性資產越多，交易成本越高，與主要專業物流業者夥伴關係越密切。企業之環境不確定性越高，交易成本越高，夥伴關係密切程度則越低。交易頻率則不影響交易成本與夥伴關係。關鍵字：交易特性、 Under the effect of the globalization and work specialization, a manufacturer has to use global supply chain to reduce cost further to gain competitive advantage. Therefore, it is important to build up a close trading relationship with logistic service providers to speed up distribution channel. Not only is it expensive but also time lasting to develop good trading relationship under environmental uncertainty. This study is based on by Williamson's (1975) Transaction Cost Theory to investigate the relationships among transaction characteristics, transaction costs and partnership between manufacturers and logistic service providers. The findings suggest that the higher asset specificity a manufacturer invest, the higher transaction costs and closer partnership it has with the major logistic service provider. The higher environmental uncertainty a manufacturer has the higher transaction costs it has. Furthermore, the higher trading frequencies with major logistic service provider, the lower transaction costs it has. Finally, the transaction costs a manufacturer has to build up relationship with the major logistic service provider have significantly positive impacts on their trading partnership.
