近年來隨著網際網路的發展，透過網路虛擬社群平台，使用者不僅能夠快速獲取需要的資訊，還能不受時間和地點的限制，隨時隨地與其他社群使用者互動交流、分享經驗、交換知識。而社會資本理論常被用來探討知識管理相關議題，並解釋虛擬社群的知識分享行為，因此本研究以社會資本理論為基礎，以社會資本的結構、關係、認知等三個構面，實際探討虛擬社群成員們的互動關係對知識品質之影響，並探討虛擬社群知識品質對使用者滿意度與知識貢獻之關係。

本研究以「背包客棧自助旅行論壇」之註冊會員作為研究對象，以網路問卷的方式進行調查。研究結果顯示：(1) 社會資本關係構面之「互惠規範」、認知構面之「共享語言」、「共享願景」對虛擬社群知識品質有正向且顯著之影響；(2) 虛擬社群「知識品質」與使用者「滿意度」之間具有正向且顯著之影響；(3) 使用者「滿意度」與「知識貢獻」之間具有正向且顯著之影響。因此，虛擬社群會員之間有共同的價值觀、目標與願景時，會員彼此互相幫助、互動交流與分享知識，進而增加虛擬社群之知識品質，而對於虛擬社群感到滿意的會員，將更有動力參與知識貢獻行為。

With the development of the Internet in recent years, users can not only quickly access the information through the virtual communities, but also interact with other users, share experiences and exchange knowledge regardless of time and location. Social capital theory has been proposed by many scholars in order to discuss the issues of knowledge management, and explain the knowledge sharing behavior in virtual community. Therefore, this study aims at investigating the relationships between knowledge quality, user’s satisfaction and knowledge contribution in virtual community from the perspective of the social capital theory.

This study conducted a questionnaire survey from the members of Taiwan Backpakers.com online community. The research results reveal that: (1) “Norm of reciprocity” of relational capital, “shared language” and “shared vision” of cognitive capital all have significant and positive effects on knowledge quality of the virtual community. (2) “Knowledge quality” of the virtual community has a significant and positive effect on user’s “satisfaction”. (3) User’s “satisfaction” has a significant and positive effect on “knowledge contribution”. Therefore, if members of a virtual community have common values, goals and vision, they will help each other, share knowledge and have good interaction with other members. Users who are satisfied with the virtual community will be more motivated to participate in knowledge contribution.
