公用服務事業員工的e化科技接受意圖－－以TAM與TTF探討

The Behavioral Intention to Use E Systems for Employees in Public Utility Company: Analysis Based on TAM and TTF

組織成員的e化科技接受意圖，是企業e化成敗的關鍵因素之一。TAM與TTF被許多學者認為是最適當的解釋理論之一。然而，過去的研究大多以民營企業為對象，比較少觸及公用事業。根據創新理論，實施新科技的過程常引發組織學習的需要，其效果對員工接受新系統的意圖有顯著影響。然而，公用事業的官僚式情境往往抑制組織學習的效果。本研究以上述論點為基礎，發展一組假說，採用問卷調查法收集資料，並以LISREL8.5檢驗模型配適度。研究結果發現TAM與TTF只能部分解釋公用事業員工的e化科技接受意圖。僅有少部分功能簡易之系統功能，如電子郵件，被頻繁使用且被視為工作上重要工具。因此，易用性是影響接受意圖的主要因素，個人自願程度與電腦效能則是影響易用性的主要外生變數。有用性甚至會抑制員工之意圖。最後，本研究提出管理與研究建議。

One of the key factors to successfully deploy e business systems lies in the employees' behavioral intention. TAM and TTF have been claimed to be appropriate explanatory theories of this issue. However, previous studies mainly focused on enterprises within private sectors. Public utility companies have been neglected by most research. Innovation theory argues that the performance of innovation implementation is highly related with the results of organizational learning induced from innovation adoption. The bureaucracy inside public utility companies, however, may retard the effects of organizational learning. A model and a set of hypotheses were derived based on the above arguments. A survey was conducted. LISREL was used to verify the research model. The results indicated that TAM and TTF can only partially explain the intention to adopt e systems. Simple functions such as e-mail were the most frequently used and important part of the system. The motives for employees of such companies to use e systems, hen ce, were not the usefulness of the system; instead, ease of use was the primary antecedent of behavior intention, and the degree of voluntariness and computer self-efficacy were antecedents of ease of use. Finally, managerial implications and future research suggestions are proposed.
