領導者之決策對於組織的影響甚大，不僅決定企業的獲利，更可能影響組織的存亡。在現今快速變遷的環境中，領導者經常面臨在時間壓力下需快速做出正確的決策，因此本研究著重於探討領導者才能對於領導者決策品質，以及團隊競爭力與績效之影響。具體而言，本研究從Sternberg所提出的WICS模式為出發點，探討「領導者智慧」、「領導者實用智力」、「領導者分析智力」及「領導者創新能力」對於「領導者決策品質」、「團隊競爭力與績效」之影響，並建構「領導者才能之競爭力模式」。至於領導者才能之競爭力模式，不僅可以做為後續相關研究之重要參考，亦可協助企業與領導者檢視其領導效能，進而做為改善競爭力與績效之重要依據。 本研究之問卷經嚴謹之程序編製，首先進行專家會議、信效度及因素分析之檢驗，之後再進行研究變項間之探討。研究樣本採立意取樣方式，以團隊為單位，每個團隊收集團隊領導者及其五位直屬部屬之調查問卷。本研究總計回收40位領導者與200位部屬之有效樣本，統計分析結果顯示，本研究所有量表皆具有良好之內部一致性信度（.754~.972）與效標關聯效度（.280~.820）。 此外，本研究根據結構方程模式驗證本研究之假設，綜合結果顯示：1. 領導者智慧、實用智力、分析智力及創新能力對於領導者決策品質具有顯著且正向之影響；2. 領導者決策品質對於團隊競爭力具有顯著且正向之影響；3. 團隊競爭力對於團隊績效具有顯著且正向之影響；4. 「領導者才能之競爭力模式」獲得實證支持。最後，研究者根據本研究結果，提出對未來學術研究與實務應用具體之建議。 / Leaders’ decisions have a great impact on organizations; they influence not only the revenue but also the survival of organizations. In this fast-changing environment, leaders always need to make fast and correct decisions under time pressure. Therefore, the focus of this study is the effect of leaders’ skills on the quality of leaders’ decisions so as to improve the competitiveness and performance of teams or organizations. The present study starts from WICS model which developed by Sternberg to examine the effect of leaders’ wisdom, practical intelligence, analytic intelligence, and creativity on the quality of leaders’ decisions, team competitiveness and performance, and to construct the competitiveness model of leaders’ skills. The development of competitiveness model of leaders’ skills could not only be used by following related studies, but also assist organizations and leaders to review leadership efficacy in order to improve the competitiveness and performance. The present study constructed the questionnaire through an expert committee, tests of reliability, validity, and factor analysis. The samples of team unit were collected using purposive sampling, and each unit included one leader and five immediate subordinates. A total of forty valid sample units which had forty leaders and two hundred immediate subordinates were collected. Through the statistical analysis, it shows the internal consistency reliability (.752-.972) and criterion-related validity (.280-.820) of all scales (leaders’ self-rating and subordinates’ other-rating) were excellent. Furthermore, according to the result of hypothesis testing and Structural Equation Modeling analysis, it shows: 1. Leaders’ wisdom, empirical intelligence, analytic intelligence, and creativity have a significant and positive influence on the quality of leaders’ decisions; 2. The quality of leaders’ decisions has a significant and positive influence on team competitiveness; 3. Team competitiveness has a significant and positive influence on team performance; 4. The constructed competitiveness model of leaders’ skills was supported. Finally, suggestions were proposed for further academic studies and practical application based on the result of the present study.
