使用者可以透過知識地圖系統來蒐集與分享知識，進而促進內隱知識關係的建立。然而，過去有關這部份的研究大都集中於知識地圖系統的設計，有關預測使用者使用知識地圖系統的行為研究則相對較少。本研究除了參考科技接受模式外，更加入系統特性與知識地圖系統自我效能等因素，建構更完整的模式來瞭解社群知識分享過程中使用知識地圖系統的行為。透過理論與實證分析，瞭解使用者對於知識地圖系統的認知，並找出影響使用者知識地圖系統採用的要素。本研究經由網路虛擬社群的資料蒐集，共獲得有效問卷 179份，以AMOS進行模式之驗證，相關數據顯示: 研究模式除了有良好的適配度外，相關假說亦都達到統計上的顯著水準。系統特性與知識地圖系統自我效能兩者對使用者的認知與行為意圖呈現正向的影響，使用者採用知識地圖系統的態度與行為意圖亦具有正向的關係，本研究結果希望能提供組織在建構與推動知識地圖系統時有效的參考。

Knowledge map systems gather explicit and acquired knowledge which can be shared, and
facilitate the emergence of tacit knowledge of new relationships. A variety of people use
knowledge map systems to engage in knowledge sharing. However, while most studies focus
on system design for knowledge map systems, predictors for a knowledge map system
adoption have seldom been addressed. This paper proposes a model to facilitate knowledge
sharing in communities of practice for a knowledge map system. Both theoretical and
empirical analyses were undertaken and are reported here to explain the factors that influence
users’ adoption of knowledge map systems to share knowledge using the technology
acceptance model (TAM) which incorporates system characteristics and knowledge map
system self-efficacy. The proposed model was empirically evaluated using survey data
collected from 179 virtual community users about their perceptions of knowledge map
systems. Overall, the data used fit well with the hypothesized relationships in the model, as all
relationships in it were statistically significant. The findings suggested that both system
characteristics and users’ knowledge map system self-efficacy positively affected user
perceptions and behavioral intention. The results also revealed a positive relationship between
attitude and intention in the adoption of knowledge map systems. Implications of these results
are discussed.
