一、大學生使用Facebook之習慣為短時間、多次數，且普遍有認為自己是其中一份子的經驗，在Facebook中分享個人知識或想法的信心程度普遍偏高。 二、大學生其分享行為傾向內控信念，當控制信念越傾向內控，其自我效能程度也會越高；而虛擬社群意識越強烈，其自我效能程度亦會越高。 三、大學生自我效能、虛擬社群意識與控制信念對於知識分享行為皆達顯著相關。 四、在所有衡量因素當中，以知識分享自我效能、歸屬感、個人態度與主觀規範對於大學生在Facebook中的知識分享行為最具有預測力。 This research aims to discuss the effect of self-efficacy, sense of virtual community and locus of control toward internet knowledge sharing behaviors.The researcher collects data through questionnaire survey,investigating the university student users''(N=447) feelings on knowledge sharing behaviors in virtual community with related variables.Then,the researcher finally carries on Pearson''s Correlation and Multiple Regression Analysis methods for data analysis.The major findings are as follows:
1.University students are used to use Facebook within short time,high frequency,and think of themselves as part of the community.In general,they have high confidence on sharing personal knowledge or ideas on Facebook. 2.University students'' knowledge sharing behaviors tend to be internal locus of control.The more tendency of internal locus of control they retain,the higher self-efficacy they have.And the stronger of sense of virtual community they retain,the higher self-efficacy they have. 3.There are significant correlations between university students'' self-efficacy and knowledge sharing behaviors;sense of virtual community and knowledge sharing behaviors;locus of control and knowledge sharing behaviors. 4.Among all factors, knowledge sharing self-efficacy,sense of belonging,and personal attitude are the most predictive of all toward university students'' knowledge sharing behaviors on Facebook.
