近年來社群網絡使用人數不斷增加，而在2012年台灣Facebook使用人數超過全台灣人口數的一半以上。社群網站的知識分享程度也隨著使用人數的增加而快速成長，並累積大量的知識。本研究欲探討社群網絡與知識分享的關聯，希望從一般使用者的角度分析社群網絡的使用行為對知識分享造成什麼影響 。
本研究採問卷式，有效樣本為152份，以SPSS及偏最小平方法（partial least squares, PLS）來進行本研究的敘述性統計與測量模型及結構模型的檢測。
主要研究結論可說明如下：(1)社群網絡使用行為與競爭優勢顯著正相關(2)社群網絡使用行為與知識交流顯著正相關(3)社群網絡使用行為與互相信任顯著正相關(4)社群網絡使用行為與達共同目標顯著正相關(5)社群網絡使用行為與互相學習顯著正相關(6)社群網絡使用行為與專業知識顯著正相關(7)社群網絡使用行為與知識數量顯著正相關(8)社群網絡使用行為與知識創造力顯著正相關(9)社群網絡使用行為與獲取知識顯著正相關。研究結論有助社群網絡產業有進一步的發展。

There are more and more people using social networking in recent years, and the users of Facebook in Taiwan have been over half population in Taiwan in 2012. With the increase of users, the knowledge sharing behavior in Facebook is not only growing rapidly but also accumulating a large amount of knowledge. This research aims to study the relationship between Social Networking and Knowledge Sharing, and to analyze the impact of user behavior of Social Networking on Knowledge Sharing in terms of average user’s perspective.
This research was performed through questionnaire survey and there are 152 valid questionnaires in this research. SPSS and partial least squares(PLS) method are applied to analyze the descriptive, measure model and structural model.
The main research findings are as follows: (1)there is significant positive correlations between the user behavior of Social Networking and competitive advantage；(2) there is significant positive correlations between the user behavior of Social Networking and Knowledge exchanged；(3) there is significant positive correlations between the user behavior of Social Networking and mutual trust；(4) there is significant positive correlations between the user behavior of Social Networking and reaching common goals；(5) there is significant positive correlations between the user behavior of Social Networking and learning from each other；(6) there is significant positive correlations between the user behavior of Social Networking and professional knowledge；(7) there is significant positive correlations between the user behavior of Social Networking and amount of knowledge；(8) there is significant positive correlations between the user behavior of Social Networking and knowledge Creativity；(9) there is significant positive correlations between the user behavior of Social Networking and obtaining knowledge. The aforementioned can provide insight for the further development of the social networking.
