摘要

隨著資訊科技的進步，點對點網路(Peer- to-Peer Networks)傳輸的使用情況已經漸漸普及。然而，由於點對點網路軟體的使用日趨盛行，許多使用者用來下載有版權的音樂或電影，因此點對點網路軟體經常伴隨著一些爭議性的話題，例如:智慧財產權。事實上，每個使用者在點對點網路裡都擁有高度自主權去決定要將資訊分享給誰、分享什麼樣的資訊、什麼時候分享資訊，我們不禁思考除了有版權爭議的多媒體檔外，知識是否可以在點對點網路裡被有效地分享呢?使用者的意向會決定使用者是否產生知識分享的行為，而使用者態度、主觀規範、使用者控制能力將會影響使用者的意向。本研究採用計畫行為理論來試著解釋點對點網路裡的使用者知識分享行為。由於缺乏現有點對點網路實際使用資料，本研究採用實驗法的方式在一個點對點網路的平台：SOKUL， 利用合作式學習活動來進行實驗以驗證根據計劃行為理論所提出的研究假說。
經由實驗結束後的47份問卷調查與在SOKUL平台資料庫所記錄的使用者真正活動行為，實驗結果顯示主觀規範顯著地影響使用者知識分享的意向。此外，實驗結果也顯示使用者行為和使用者意向有正面的顯著關係，符合計畫行為理論所提出的論點。進而，根據個案訪談，本研究討論導致實驗結果的因素。最後，提出相關後續修正與繼續探討的研究方向。

Many peer-to-peer (P2P) networks have been popularly used for file sharing. However, P2P applications have also been notorious for sharing copyrighted digital goods besides for the free riding problem. Inherent in the characteristics of P2P networks that a peer acts both as a content provider and a consumer, a peer is granted autonomy to decide what, with whom, and when to share. Is it possible that a user can effectively share knowledge with others via a p2p network? A user’s attitude, normative, and control believes may influence a user’s intention to share knowledge through P2P networks. This study adopts the Theory of Planned Behavior (TPB) to attempt to explain the knowledge sharing behaviors on a P2P network. Due to the lack of empirical data, this study conducts experiments on a P2P network platform, SOKUL to test the hypotheses derived from TPB in collaborative learning activities.
Through the survey of 47 subjects and transaction log data of SOKUL, experimental results indicate that subjective norm significantly influences peers’ intention for knowledge sharing under a collaborative learning circumstance, and behavior of knowledge sharing is indeed positively related to intention which matches with what TPB model claims. Based on these results, implications of the findings and future research directions are also discussed in this study.
