以UTAUT 2探討國中生智慧手機與平板電腦使用之研究

A UTAUT-based Study on the Usage of Smartphones and Tablet PCs 2 by Junior High School Students

瞭解個人對於資訊科技的接受與使用行為一直是資訊系統研究中的重要議題，本研究採用UTAUT 2模式剖析國中生對於智慧手機與平板電腦的使用行為，進一步說明UTAUT 2模式是否適合解釋台灣地區國中生使用智慧手機與平板電腦之行為。研究工具採問卷設計，樣本為臺南市某國中學生，共回收有效樣本342份。接著利用Smart PLS 3軟體進行結構模式潛在變數間的因果關係分析與檢定。結果發現：(1)行為意圖會受到績效期望、享樂動機、使用習慣的正向影響；(2)使用行為則受到促進條件、使用習慣、行為意圖正向的影響。(3)隨著經驗的增加會增強享樂動機對行為意圖的影響力。(4)國中女生會隨著使用習慣的增加而比國中男生更加強對智慧手機與平板電腦的使用行為。(5)研究模型在行為意圖的解釋力高達82.3%，對使用行為的解釋力亦有44%。研究結果可作為相關單位進一步應用於教育與商業用途之參考。

Understanding individual acceptance and use of information technology is one of the most developed streams of information systems research. This study, based on the Unified Theory of Acceptance and Use of Technology 2 (UTAUT 2), is to explore the behavioral intention and use behavior of the junior high school students regarding smartphones and tablet PCs. Furthermore, this study explored whether the UTAUT 2 mode is suitable for the verification of such a study on junior high school students in Taiwan. The research conducted a questionnaire survey, with study samples from junior high school students; 342 valid samples were collected. Smart PLS was used as the SEM analysis tool. The research results indicated that (1) Performance expectancy, hedonic motivation, and habit have positive impacts on behavioral intention. (2) Facilitating conditions, habits, and behavior intention have positive influences on use behavior; (3) Increased experiences strengthen the influence of hedonic motivation to behavioral intention. (4) As their habits increase, girls tend to use smartphones and tablet PCs more frequently than boys do; and (5) This model explained about 82.3% of the variance in behavioral intention to use smartphones and tablet PCs and about 44% of the variance in the use behavior. The relevant findings could be reference for application in education and business.
