本研究旨在探討旅遊網站使用者持續採用行為，以「期望確認理論」（Expectation Confirmation Theory，ECT）為基礎，並透過整理過去有關旅遊網站特性、科技採用 與資訊系統成功的相關文獻，歸納出影響旅遊網站持續採用之相關因素，藉以提出一 套能夠適用於旅遊網站情境之理論模式。在「期望確認理論」相關文獻中，尚未有研 究以「背包客」（Backpackers）為研究對象來探討系統使用者之持續採用行為，本研 究延伸期望確認理論之相關變數，以讓此理論應用在旅遊網站的情境上更臻完整。本 研究以臺灣地區的背包客為研究對象，指非透過旅行社安排，曾經進行國內、外自助 旅遊者為主，經由網路問卷的方式，共回收251 份有效問卷，並使用LISREL 軟體進 行統計分析資料，結果顯示多數假說均獲得支持。本研究有以下發現：(1)旅遊網站品 質特性（資訊品質、系統品質及服務品質）對「確認程度」有正向顯著之影響；(2) 「確認程度」對旅遊網站使用特性（知覺有用性、知覺易用性）與「使用者滿意度」 有正向顯著之影響；(3)旅遊網站使用特性（知覺有用性、知覺易用性）對「使用者滿 意度」有正向顯著之影響；(4)旅遊網站使用特性（知覺有用性、知覺易用性）對「持 續使用意願」沒有正向顯著之影響；(5)「使用者滿意度」對「持續使用意願」有正向 顯著之影響。 最後，根據研究結果提供旅遊網站業者一些有效管理旅遊網站系統營 運之實務建議。

In this study, a research is conducted on backpackers’ continuing use in travel websites based on Expectation Confirmation Theory (ECT). Efforts are made to generalize factors that influence continuing use behavior through the literature review on the topic of websites´ characteristics, information technology adoption, and Information systems success. So far, there hasn’t been any research in ECT investigating continuing use in subjects of backpackers. Therefore, we extended the variables of ECT to better explain the continuing use of travel websites under different context. This research subjects were mainly focused on backpackers in Taiwan who used to travel domestically or internationally on their own rather than traveling through the arrangement of travel agency. Data analysis is conducted via LISREL statistical analysis, with 251 valid questionnaires returned. This study concludes five main results with using travel websites, including: (1) Perceived quality (information quality, system quality and service quality) of travel websites has a positive impact on the expectation confirmation. (2) Expectation confirmation has a positive effect on the extent of perceived use characteristics (perceived usefulness, perceived ease of use) of travel websites and use satisfaction. (3) Perceived use characteristics of travel websites have a positive impact on the use satisfaction. (4) Perceived use characteristics of travel websites have not a positive impact on continuing usage intention. Finally, use satisfaction of travel websites has a positive significance on continuing usage intention. On the whole, most of hypotheses were supported. Implications are also provided.
