近年來,在資訊科技進步與網路新興科技發展的浪潮下,各類型的行動社交網絡應用程式(mobile social networking application,以下簡稱MSNA)如雨後春筍般蓬勃發展,諸如Facebook、Twitter、LINE等越來越多的行動社交網絡應用程式(MSNA)已改變人們的溝通方式,透過網際網路人們可以跨越時空、地域的限制,基於不同目的作經驗、情感、價值觀、資訊及知識的交流。本研究主要是根據需求層次理論(Maslow’s hierarchy need theory ,1954)來探討成員使用MSNA的知識分享行為。本研究想了解自我提升及自我肯定等因素,是否為影響使用MSNA知識分享的重要前置因素 ? 同時,探討人們在MSNA中進行知識分享是否受到調節焦點理論而影響其知識分享的意願 ? 並探討人們在MSNA中進行知識分享是否能獲得幸福感 ? 此外,亦想了解過去的虛擬社群經驗是否會影響人們在MSNA中的知識分享及幸福感受。因此,本研究以Line代表行動社交網絡應用程式(MSNA)為研究標的,探討Line群組成員的知識分享及其對虛擬生活幸福感之影響。 As advancement and the development of information technology, various types of mobile social networking applications (MSNA) have sprung up, such as Facebook, Twitter, and LINE. The MSNAs have changed the way of people communication. Through the Internet people can exchange experiences, emotions, values, information, and knowledge across time and space for different purposes. This study is based on Maslow''s hierarchy of needs theory (1954) to explore the use of MSNA knowledge sharing behavior. We think that members are willing to share knowledge is based on Maslow''s hierarchy of needs. Therefore, this study would like to know whether Self-enhancement and Self-affirmation were an important prerequisites for knowledge sharing in MSNA, and whether knowledge sharing in MSNA is affected by different personality traits. Besides, we want to understand whether they will be able to share knowledge in MSNA, and whether they will be able to share knowledge and share their happiness in MSNA. Therefore, this study uses Line as the research object to explore the Line group members of the knowledge sharing behavior in MSNA and its impact on virtual life happiness.
