現今社交媒體的使用在企業組織中極為盛行，而不同的社交媒體具備不同的特性，造成不同社交媒體使用上的差異。在臺灣，社交媒體LINE已成為許多人重要的溝通管道。本研究主要探究某企業員工使用LINE作為工作相關的人際溝通及資訊傳遞管道時，員工感知使用社交媒體的可供性特徵（包含：可見性、持續性、編輯性及關聯性）、工作群組的組織權力及感知使用社交媒體價值之間的關係。本研究以問卷調查的方式，回收共234份有效問卷，採用探索性因素分析萃取出可見性、持續編輯性、組織權力、實用價值及享樂價值等五個構念。此外，企業員工參與LINE工作群組，感受到的LINE可見性、持續編輯性及工作群組的組織權力分別能正向預測感知實用價值及享樂價值。然而，本研究採取單一時間點的自陳式問卷，無法推論變項之間的因果關係，有待後續研究彌補此不足之處。

The use of social media for work has become more and more popular in companies and organizations. Different social media possess different characteristics also called affordances which result in different application forms of social media by users in various contexts. In Taiwan, LINE is one of the most popular social media. This study explores the relationships between the affordances of LINE (i.e., visibility, editability, persistence, and association), the organizational power in the work-related LINE groups, and employees’ perceived value of LINE. Using the survey method, 234 valid responses were analyzed, and the EFA results identify five constructs: visibility, persistent editability, organizational power, perceived utilitarian value, and perceived hedonic value. Additionally, the visibility and persistent editability of LINE and the organizational power perceived in the LINE work-related groups can positively predict the employees’ perceived utilitarian value and hedonic value of LINE use. Yet, employing the one-shot self-report survey method, this study cannot verify the cause-effect relationship between the variables, and future research could further tackle this issue.
