知覺關鍵多數與物聯網科技採用－干擾與中介混合模式
Perceived Critical Mass and the Adoption of IoT Technology : A Moderated Mediation Analysis
摘要
研究目的：隨著工業4.0時代來臨，物聯網（Internet of Things,IoT）成為發展產業重要的科技運用。本研究從「知覺關鍵多數」角度探討大學生採用物聯網的行為意向，並以科技接受模式（Technology Acceptance Model）中之「知覺有用性」作為中介變項，瞭解是否具有中介「知覺關鍵多數」對採用物聯網行為意向的影響；並以「性別」為干擾變項，了解干擾變項對中介效果的影響，進行所謂的「干擾型中介」探討。研究方法：本研究採調查研究法，針對大學圖文傳播藝術科系學生進行施測，以結構方程模式進行驗證性因素分析（Confirmatory Factor Analysis,CFA）、結構模型分析；前者進行收斂效度、及區別效度檢定；後者則檢視各項配適度指標，並計算各路徑的效果。研究結論：知覺關鍵多數對「物聯網」新科技使用意向具有直接效果，且能藉由「知覺有用性」中介的間接效果產生對行為意向的影響。同時，男、女性群組無顯著性差異，表示「性別」對知覺有用性於影響知覺關鍵多數與採用物聯網行為意向之間「不具干擾效果」。研究建議：建議可以進行多重中介效果研究，並由大學生的師長和同學之間多加推廣物聯網的知識、功能性及其相關之應用，形成一種多數人使用的氛圍，再由此因勢利導，讓更多相關科系的大學生提高採用物聯網的行為意向。

Purpose of Study: The study aims to investigate the factors that influence college students' intentions to adopt Internet of Things (IoT) technologies, explores ＂Perceived Usefulness, PU＂ as a mediator of the impacts of ＂Perceived Critical Mass, PCM＂ on behavioral intentions and examines gender as a moderator of the effects of PCM, PU on college students' intentions to adopt IoT. Methodology: The proposed model was empirically evaluated using questionnaire survey data collected from 209 survey respondents to test the research model through the use of structural equation modeling. Findings/Conclusions: The results indicate that PCM, PU significantly affect behavioral intentions to adopt IoT directly. The PCM also impact PU, which in turn impacts college students' intentions, PU mediates the effects of PCM on behavioral intentions to adopt IoT. At the same time, there is no significant difference between the male and female groups, indicating that PU affecting the relationship between PCM and behavioral intentions to adopt IoT are not moderated by gender. Suggestion: The college students' willingness to use IoT technology from the perspective of Multiple Mediation Analysis should be conducted in the following research. More future directions for methodological and empirical research on the Adoption of IoT are presented.
