企業資源規劃(ERP)系統在台灣企業已發展普及，但ERP系統績效評估仍舊是企業所關心的課題。以往的研究顯示ERP系統成員對ERP系統的易用性、有用性的認知程度，會影響使用者對ERP系統的持續使用意願及行為，但影響其意願與行為，是受到更多因素影響。有鑒於ERP建置成本高，對於使用後之有用性及持續使用意願及行為亦深具探討價值。 本研究採用調查研究法，透過問卷的形式來蒐集資料，問卷對象為ERP使用人員，加入了科技接受模式3中的工作相關性、認知外部控制、電腦自我效能、來探討易用性、有用性對持續使用意願及行為的影響，並加入習慣因子來探討持續使用的行為。嘗試從分析結果中瞭解研究對象對研究構面是否影響ERP系統能持續改進的重要關鍵因素。本研究經實際驗證顯示，知覺有用、習慣為直接影響持續使用ERP系統的意願之因素，知覺易用影響持續使用ERP系統的意願較薄弱。 Enterprise resource planning (ERP) systems have been extensively implemented in Taiwan, but its performance evaluation is still the focus of concern. Previous studies have shown that ERP systems users’ perceived the ease of use and perceived usefulness will affect the continued use of ERP systems and behavior, but more factors may also affect their continuance to use. In view of the high cost of ERP implementation, this area of research needs more investigation. In this study, the survey research method was used. A questionnaire was designed to collect information about job relevance, perceptions of external control, and computer self-efficacy. Those data are related to the technology acceptance model 3. And habit is incorporated into the model as a mediating factor to explore the continued usage behavior. The results show that Perceived Usefulness and Habit have significant effect on the intention of continuing to use ERP system, but Perceived the Ease of Use does not have significant influenced.
