Abstract: 本研究是以台灣地區電腦零組件的發展，來探討企業競爭策略形成要素與策略關係之研究。本研究採用Lin and Pao（2004）所提出的策略管理架構，透過個案公司的使命陳述，進行對內部環境、產業環境及總體環境的評估，以7S模型、五力模型及PESTEL模型等三大構面，建立本研究分析架構，歸納出企業競爭策略形成的重要關鍵因素，以提供交換式電源供應器產業中有關節能產品之參考。其主要結論如下：
一、本研究個案公司在使命陳述下，分析評估其內部環境、外部之產業競爭環境及總體環境，歸納出其競爭策略形成要素圖，當個案公司綜合考量三大環境各要素重點，將有助於其策略形成，可作為該公司特定競爭策略制定與修正參考。
二、在個案公司的使命陳述下，根據個案公司環境評估所形成的最適競爭策略必須藉由「技術發展」來加以實踐，所以其最適競爭策略與「專注高階產品研發」的特定策略相契合。個案公司必須藉由「專注高階產品研發」來提高獲利，進而達成企業使命，以成為在產業的領導地位。
This study concentrates on the current development of Computer parts Industry in Taiwan with emphasis on the relationship between business strategy formulation factors and strategies so as to assess the internal environmental factors and external environmental factors through the mission statement of target company and thus summaries the critical factors related to the strategy formulation, thereby initiating business strategies and presenting the findings to the Switching Power Supply Industry service providers. In this study, the strategy management structure suggested by Lin and Pao (2004) was adopted. Through the mission statement from the case study companies, evaluations on internal environment, industrial environment, and exterior environment had been performed. We generalize the conclusions with the explosive case study method as following：
