Facebook 社群網站快速擴張與活躍用戶數持續增長的現象中，Facebook 社群網站平台在過去文獻已被證實是能夠影響人際關係，而如何更進一步促進人際關係互動也是社群網站管理者的首要考量。社群網站使用者在網站中活動記錄，也如同一個人在現實生活中活動的記錄。在過去的文獻中，蒐集過去歷史記錄是使用生命史行事曆 (LHC) 來蒐集回顧性資料，從中可以發現運用過去生活記錄可以對現在的生活產生一定的影響力。 因此本研究以Facebook 所提供「我的這一天」的功能，這功能與生命史行事曆是相似的概念，探討分享個人過去回顧動態對社交關聯的影響。在研究模型中以社交分享為中心，加上「關係強度」、「同質」、「信任」、「規範影響」、「資訊影響」五個因素影響社交分享，進而探討社交分享對Facebook 社群環境與人際關係的心理認知結果。 研究結果發現，在社群網站中使用者對於朋友關係強度的程度沒有明顯的區分，因此無法證實使用者分享個人過去回顧動態會受到關係強度所影響；此外，可以證實分享個人過去回顧動態會受到「同質」、「信任」、「規範影響」、「資訊影響」所影響。也能證實分享個人過去回顧動態動對Facebook 環境與人際關係的心理認知有正向的結果。 在管理意涵方面，運用生命史行事曆到社群網站中是值得一再被探討的議題；在學術貢獻方面，在針對社群網站探討社交分享的文獻少之又少，期望本研究之結果對社交分享的研究領域，奉獻一己之力。;The phenomenon that social network site Facebook and active Facebook users have grown up, how to increase interpersonal interaction? Many literatures had confirmed that the Facebook platform can influence interpersonal. Social network sites managers should consider how to make interpersonal interaction continue to increase. Users do something on Facebook are similar to history of their real life. This history memory that we called ‘retrospective data’ in our research. In the past, most researchers have used Life History Calendar (LHC) as a tool to collecting retrospective data in their research, and make it more influential to users, but seldom researches use this concept on social network sites. Accordingly, we use Facebook ′on this day′ as a topic, this concept is similar to Life History Calendar. The purpose of research is to find the influence of sharing personal memory to look back on social connectedness. Specifically, our research model that use tie strength, homophily, trust, normative and informational influence as an important influential factor to social sharing. And then proof the influence of social sharing be associated with positive psychological outcomes. The results confirm that homophily, trust, normative and information influence are positively associated with user′s overall social sharing, whereas a negative relationship was found with regard to tie strength. This study suggests that sharing ′on this day′ on Facebook is a unique phenomenon with important social connectedness implications. According to the results of this study, we expect to dedicate own power in the field of social sharing.
