虛擬社群已經被廣泛用於終身學習。然而，過去學者們著重在外在動機探討人們從事終身學習之意圖，而內在動機卻鮮少獲得學者們的關注。外在動機意指外在事物具有誘因促使人們被動地產生行為意圖，而內在動機意指人們主動地產生行為意圖。換言之，內在動機才是驅使人們自主的產生行為意圖，進而產生實際行為。因此，學習者若能瞭解人們透過虛擬社群從事終身學習意圖之內在動機，將可以促使更多人共同學習。本研究利用需求理論作為使用者的內在動機探討人們透過虛擬社群從事終身學習意圖的關鍵因素。研究結果證實(1)滿意度是人們持續使用意圖的重要影響因素。(2)自我實現需求是滿意度的主要影響因素，其次是自尊需求。(3)生理需求會顯著影響自我實現需求; 安全需求與社會需求會顯著影響自尊需求。其結果意謂著若社群網路服務開發者所設計的虛擬社群符合人們之滿意度，將能夠促使更多人透過虛擬社群從事終身學習。再者，人們若想聚集更多人透過虛擬社群之分享功能達成終身學習之成效，他們首先須試圖說服人們運用此方法從事終身學習能夠獲得所需之知識，以達成他們的理想、夢想。然而，本研究只著重在人們從事終身學習意圖之內在動機，但或許有其它潛在外在動機影響人們持續使用虛擬社群從事終身學習之意圖。因此，未來研究者可以整合內在動機與外在動機，並以更全面的方式探討人們持續使用虛擬社群從事終身學習意圖之影響因素。

Virtual communities have been widely used for lifelong learning. However, in the past, scholars focused on extrinsic motivation to explore people’s intention to engage in lifelong learning, while intrinsic motivation has rarely received the attention of scholars. Extrinsic motivation means that external things have incentives to urge people to passively generate behavioral intentions, while intrinsic motivation means that people actively produce behavioral intentions. In other words, intrinsic motivation is to drive people to produce behavioral intentions autonomously, which in turn produces actual behavior. This study uses needs theory as a user's intrinsic motivation to explore the key factors for people's lifelong learning intentions through virtual communities. The results of this study confirm that (1) satisfaction is an important factor in people's continuous use intentions. (2) The self-actualization needs is the main influencing factor of satisfaction, followed by the needs for self-esteem. (3) Physiological needs can significantly affect self-realization needs; Security needs and social needs can significantly affect self-esteem needs. The result is that if the social networking service developers designed the virtual community to meet people's satisfaction, it will enable more people to engage in lifelong learning through the virtual community. Furthermore, if people want to gather more people to achieve lifelong learning through the knowledge sharing function of the virtual community, they must first try to persuade people to use this method to engage in lifelong learning and gain the knowledge they need to achieve their ideal and dreams. However, this study focuses only on the intrinsic motivation of people engaged in lifelong learning intentions, but there may be other potential external motivations that affect people's intention to continue to use virtual communities for lifelong learning. Therefore, future researchers can integrate intrinsic motivation and extrinsic motivation, and in a more comprehensive way, explore the influencing factors of people's continuous use of virtual communities to engage in lifelong learning intentions.
