社群網站在全球掀起一股熱潮，成為人際聯繫互動之新平台；隨著社群網站功能日增，使得社群網站更容易收集、儲存和發送個人的資訊，隱私也成為使用者與網站經營者關心的議題。經營者為追求利潤最大化，需考量如何充分運用使用者的資訊於行銷和其它網站功能上，同時，使用者也關心於揭露詳細個人資料於社群網站的同時，個人資訊被濫用的程度；由於社群網站經營者亟欲充份利用資訊之企圖與使用者對於資訊揭露之顧慮往往存在差距，因此產生「隱私悖論」相關議題，而隱私悖論於使用者對社群網站之信任與進一步接受該社群網站亦產生直接影響。雖然「隱私悖論」議題對於社群網站之經營管理日益重要，但少有學者探討「隱私悖論」如何影響社群使用者對社群網站之信任與接受，因此，本研究擬探討社群網站中使用者與網站經營者間對使用者的隱私關注程度是否存在顯著差異，並分析此關注程度的差異是否將進一步影響使用者未來持續使用社群的意願。為達成此目的，本研究擬導入技術接受模型 (Technology Acceptance Model)，以使用者對社群網站之隱私顧慮、制度信任(含情境常態與結構保證)、計算性信任、與熟悉度做為外在變項，探討「隱私悖論」是否將影響使用者未來持續使用某社群網站；此外，研究發現「認知有用性」與「認知易用性」亦影響新型資訊科技產品之使用意圖，因此，本研究亦導入此二因素作為研究變項。為分析影響使用者信任並進而接受社群網站，持續使用的因素，本研究擬針對社群網站之一般使用者與專家分別以偏最小二乘法 (Partial Least Square，PLS)與基於決策實驗室之網路流程法(Decision Making Trial and Evaluation Laboratory Based Network Process) 建構影響社群網站技術接受因素與使用者行為間之關係架構，並比較專家與一般使用者對於「隱私悖論」於使用者信任社群網站並進一步接受網站、持續使用之重要因素。本研究之結果將可作為社群網站經營者於行銷與服務策略之用。

Social network sites surged recently all over the world and have become new platforms for intimate communications. As the functionality of social networks was enhanced, users’ own information can be collected, stored, and manipulated much more easily. Privacy concern has thus become the most concerned issue by both users and website operators. The operators intend to maximize the profits and need to consider how users’ confidential information can be fully utilized in marketing and aspects of social network operations. At the same time, users usually concern over the misuse of private information by the website operations at the moment when disclosing individual details on social networking sites. Apparently, a significant gap exists between the website operators’ intention to fully utilize the private information as well as the users’ privacy concerns about disclosing information on the social networking sites. Such cognition gap, or the "privacy paradox", influences users’ trust on a specific social networking site directly and further influence users’ acceptance and continuous usage of the site Albeit such privacy paradox issues have been becoming daily important for the social network operators as well as users, very few scholars tried to uncover how privacy paradox influences users’ privacy concern and the social network sites structural assurance, which will influence the user whether to accept of social network sites or not. In this study, TAM (Technology Acceptance Model) is the theoretical basis, applying users' private disclosure behavior; disclosure risks perception, and the extent of privacy settings in the social networking sites as main variables. Whether it influences users continued interactive in the social networking sites in the future. In addition, in the past study found that perceived usefulness, perceived ease of use and the interaction strength for modern technology services or products influencing use intention, so adding these factors as research variables. It conducted a questionnaire survey targeted at end users and experts, respectively, with Partial Least Square (PLS) and "new multi-criteria model" (Decision Making Trial and Evaluation Laboratory Based Network Process, DNP) as the construction and analysis. To explore which variables influence users in social networks in the future continued interaction intention, and comparing the two methods, end users and experts to that site's privacy concerns for the social networking site, privacy setting mechanism, and technology acceptance at the similarities and differences. Results of this study, the author hopes to provide the site operators in the marketing and service strategies to develop privacy and competitive ref.
