使用供應鏈管理，建立密切的夥伴關係，以降低成本，進而提升經營績效，儼然成爲企業最關注的議題。本研究對國內製造業者進行調查研究，並著重於投機主義的探討。大部分的過去研究著重於一些構念對投機主義的影響，例如資產專屬性、環境不確定性、信任、承諾，並未更深入的探討構念中的構面，因此本研究目的在於分析資產專屬性、不確定性、資訊不對稱性的構面，對投機主義的影響，以供企業在進行供應鏈管理時有一適當之方針。研究方法採調查研究法，共寄出350份問卷，有效回收問卷爲96份，回收率27.42%。以複迴歸分析進行假設檢測，主要結果如下：一、上游供應商與下游製造商間的有形與無形專屬性投資，對其整體專屬性投資有顯著地影響。二、上游供應商與下游製造商間的供給與需求不確定性，對其整體不確定性有顯著地影響。三、上游供應商與下游製造商間的策略與作業資訊不對稱性，對其整體資訊不對稱性有顯著地影響。四、上游供應商與下游製造商間的整體專屬性投資、整體不確定性、整體資訊不對稱性，對其合作關係的投機主義具有顯著地影響。

Using the supply chain management, establishing the close partnership, reducing the cost, and then raises management performance, has become the issue which enterprises most care about. Thus, this research aims to investigate the domestic manufacturing industry, and focuses on the discussion of opportunism. Most research in the past emphasized the influence of some constructs on opportunism, for example, the asset specificity, the environmental uncertainty, trust, commitment; few research explore dimensions in those constructs. Therefore, the research is focusing on the influence of dimensions of the asset specificity, the uncertainty, and the information asymmetry on opportunism in order to offer the enterprises having suitable policy when they are managing supply chain. The research uses the investigation method, in all mails out 350 questionnaires, acquires 96 effective questionnaires, and effective return ratio is 27.42%. Research hypotheses are tested by multiple regressions. The main results are as follows: 1. Visible and invisible specificity investments between upstream supplier and downstream manufacturer have significant influences on overall specificity investment. 2. Demand uncertainty and supply uncertainty between upstream supplier and downstream manufacturer have significant influences on overall uncertainty. 3. Strategic information asymmetry and operational information asymmetry between upstream supplier and downstream manufacturer have significant influences on overall information asymmetry. 4. The overall specificity investment, the overall uncertainty, and the overall information asymmetry have significant influences on opportunism in cooperation relationship between upstream supplier and downstream manufacturer.
