如何有效率管理或執行組織間交易活動，是學術界及實務界有興趣的議題。以成本觀點觀之，交易組織管理交易活動愈多，即代表付出的管理成本愈高。 本研究以交易買方角度，思考組織間交易過程中，我方管理交易活動複雜度。故本研究焦點設定在我方在決定與他方進行交易後，交易過程中的協調與管理活動。研究問題主要欲瞭解我方在決定交易對象後，執行該交易的管理成本為何；即瞭解影響我方管理交易付出活動多寡的因素為何。 為能確認研究議題相關之實務現象，本研究先進行個案研究，訪談六家電子產業公司、十二個交易個案。與理論對話後，整理出「我方交易管理複雜度」構面，並建構出本研究架構﹕考量交易特性、交易重要性及交易經驗與知覺他方投機行為對我方交易管理複雜度之影響。進一步地進行實證研究。 本研究透過問卷調查，共蒐集電子製造業產業170個有效交易樣本，研究假設經檢測後，本研究結果發現，在組織間交易過程中影響我方交易管理複雜度之因素包括：(1)交易任務流程的相互依賴程度愈高，因作業流程彼此銜接或為合作的資訊取得需要，我方管理重點將置於流程的協調，故我方會付出較多的管理行為來溝通協調交易的作業，包括對內整合與對外(即他方)溝通協調的管理活動。(2)交易任務不確定程度，包括交易品質的不確定與交易數量的不確定，我方將增加管理複雜度，例如進行監督、增加互動頻率或溝通來降低品質與交期的不穩定。(3)交易的重要程度高，表示該交易標的物取得對我方具有潛在優勢。當交易的作業重要性愈高時，我方在管理該交易時將增加管理行為取得或增加我方權力、或降低對他方的依賴，故我方交易管理複雜度將提高。(4)當我方知覺到他方有投機行為時，因交易任務流程相互依賴高的情況下，我方擔心資訊不對稱可能造成我方損失、或擔心我方須不平衡地多付出，我方除加強溝通協調取得更多作業資訊外，也須付出其他監督他方行為成本，形成我方整體交易管理愈趨複雜。 / Managing inter-organizational transactions efficiently is an important issue in practice and in research field. From cost perspective, when an organization manages transaction activities more, it pays the management cost more. This study takes the view of the buyer organization on transactions, and it considers the management complexity for inter-organizational transactions. It focuses on coordination and management for inter-organizational transactions after buyer organizations decided the transaction party. In other word, this research wants to explore what influence buyer organization to manage inter-organizational transaction on management cost. In order to explore the issues, this study adopted two study researches. At first, this study took 12 case studies form 6 companies to develop the construct of management complexity and build this research framework. Secondly, the study collected 170 samples of transaction in electronic industry by questionnaire investigation. The findings include below. (1) The higher the task-process interdependency is, the more management complexity buyer organizations pay for coordinating, communicating inter-organizational operational process or gathering more transaction information. (2) Task gets more uncertainty, including quality uncertainty and quantity uncertainty of transactions, then buyer organization will do more management complexity, e.g., monitoring transaction party and interacting frequently to each other. (3) As the transaction is important to buyer operations, buyer organization would do more management complexity in order to get more power in inter-organizational relationship or reduce dependency on transaction party. (4) If buyer organizations feel the transaction party opportunism, they would pay more attentions to safeguard. Especially, buyer organization will do something more to prevent getting loss from asymmetric information, when the task-process is getting more interdependent. Hence, the higher task-process interdependency trends to make buyer organizations pay more management complexity, when buyer organizations perceive higher opportunism
