本研究係以Davis et al.(1992)所提出之修正俊TAM以及Igbaria et al.(1996)的研究模型爲基礎，並参酌知識管理系統具有鐲特異質性的個人動機舆社會系絡議题，建構使用者接受知識管理系統之模型。研究對象爲台灣高科技產業員工共519份有效問卷，連用結構方程模式(SEM)驗證實徵资料舆理諭模型之契合度，研究結果顯示：(1)本研究所提出之模型與實徵资料檢测之後，證實在高科技産業環境脈絡下，具有相當優良之模型契合度，顯示本模型具佳之理喻稳健性舆實務適用性；(2)社會系絡的兩個因素：主颧規範舆信任均這影響知識管理系統使用者個人動機因素（有用性認知舆愉悦性認知）之顯著直接影響因素；(3)社會系絡因素（主颧規範與信任）同時也是輸出品質、易用性認知舆個人動機因素（有用性認知、愉悦性認知）之間的重要中介變项；(4)算計爲基礎的信任、制度爲基礎的信任、知識爲基礎的信任爲組成信任三個重要的了構面；(5)主颧規範、有用性認知、愉悦性認知篇系統使用之顯著直接影響因素，其影響力顺序爲有用性認知、主颧规範、愉悦性認知。這個結果也舆Igbaria et al.(1996)之實證結果相同。 本研究的結果闡述營造組識整體優質之社會系絡氛圍興提升組識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，實證結果舆意涵可提供高科技企業發展配套激勵方案之参考。

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).
