運用TAM模式探討個人動機與社會系絡影響使用者接受知識管理系統之因素－－以高科技公司為例

Using TAM to Study the Personal Motivations and Social Context Factors Influence the Acceptance of Knowledge Management Systems-Based on High Technology Firms＇ Samples

本研究係以Davis et al.（1992）所提出之修正後TAM以及Igbaria et al.（1996）的研究模型為基礎，並參酌知識管理系統具有獨特異質性的個人動機與社會系絡議題，建構使用者接受知識管理系統之模型。研究對象為台灣高科技產業員工共519份有效問卷，運用結構方程模式（SEM）驗證實徵資料與理論模型之契合度，研究結果顯示：（1）本研究所提出之模型與實徵資料檢測之後，證實在高科技產業環境脈絡下，具有相當優良之模型契合度，顯示本模型具極佳之理論穩健性與實務適用性；（2）社會系絡的兩個因素：主觀規範與信任均為影響知識管理系統使用者個人動機因素（有用性認知與愉悅性認知）之顯著直接影響因素；（3）社會系絡因素（主觀規範與信任）同時也是輸出品質、易用性認知與個人動機因素（有用性認知、愉悅性認知）之間的重要中介變項；（4）算計為基礎的信任、制度為基礎的信任、知識為基礎的信任為組成信任三個重要的子構面；（5）主觀規範、有用性認知、愉悅性認知為系統使用之顯著直接影響因素，其影響力順序為有用性認知、主觀規範、愉悅性認知。這個結果也與 Igbaria et al.（1996）之實證結果相同。本研究的結果闡述營造組織整體優質之社會系絡氛圍與提升組織成員正向之個人動機誘因在使用者接受知識管理系統因素中的重要性，實證的結果與意涵可提供高科技企業發展配套激勵方案之參考。

Based on revised TAM model (Davis et al., 1992) and Igbaria et al.(1996), the research aims at high technology firms in Taiwan to develop the user’s acceptance model of knowledge management systems. Using Structural Equation Modeling (SEM), we examined the proposed hypotheses to verify the fit of empirical data and model. The conclusions are (1) According to the statistical results, the proposed success model fits very well for the high technology samples of individual industry. (2) The two factors of social contexts: subjective norm and trust are the significantly direct antecedent of system user acceptance. (3) The effects of output quality, perceived ease of use on individual motivations are mediated by social contexts’ factors. (4) All of the three dimensions of trust: calculative-based trust, institution-based trust and knowledge-based trust have significant influences on trust. (5) Subjective norm, perceived useful and perceived enjoyment are the significantly direct antecedent of system user acceptance, and the influential order is perceived useful, subjective norm and perceived enjoyment. And the result is consistent with the research of Igbaria et al. (1996).
