目前市面上有兩大類型虛擬社群工具：聊天交友網路社群工具（以MSN Messenger為例）以及交換訊息網路社群工具（以Facebook為例）。這類軟體對上班族影響甚鉅，畢竟，在上班的空閒時間，能利用虛擬社群軟體與朋友交流，可以消除上班的緊張氣氛，也可以藉此與友人分享喜怒哀樂，因此，這類虛擬社群軟體頗獲上班族的喜愛。然而，隨著後者市場的擴充，卻見到前者市場持平甚或逐漸衰退，而後者興起的趨勢。更於2013年初，微軟將MSN Messenger功能完全與Skype整併，並由後者取代前者名稱，以試圖挽回頹勢，可見一般。因此，本研究以上班族為研究對象，探討社群工具之轉換使用意圖，並利用科技接受模式（Technology acceptance model，TAM）作為主要研究架構，來進行研究分析。本研究發現，上班族是否會轉換社群工具會取決於使用態度，而使用態度又取決於他們對社群工具的認知有用性與認知易用性。本研究結果可供網路社群業者作為參考。
There are two types of community tools on the Internet: chatting with friends (e.g. MSN Messenger), and sharing information with friends (e.g. Facebook). In nowadays networking era, employees are used to use community tools to communicate with friends on working break. However, in these years, we found that the market of pure chatting tool is declining, but the sharing-information tool is thriving in these years. Such a phenomenon shown among employees is huge. What cause the market evolvement between chatting and sharing-information tools is important to discuss. This study used technology acceptance model (TAM) to find the causes. The results showed that employees would intend to use community tools based on use attitude, and use attitude is depended on their awareness of perceived usefulness and perceived ease of use.
