摘要

本研究深入探討使用者對於資訊系統持續使用意圖之影響因素，研究中除了建構持續使用意圖模式外，更以網路教室及入口網站為目標系統，採交叉效度檢驗所建立的模式是否具有跨群組的特性。研究結果發現，在跨樣本交叉效度，無論是以測定樣本或效度樣本為基準模式，兩組樣本在結構係數均得到一致的結果，顯示本研究模式具有跨樣本特性，可適用於不同類型的資訊系統。各變數的關係為，確認性與滿意度間雖無直接關係，但可透過知覺有用性與知覺易用性間接影響滿意度，又確認性與知覺有用性及知覺易用性成正向關係。另知覺易用性會正向影響知覺有用性，而知覺有用性又為影響滿意度的重要因素，至於知覺有用性對持續使用意圖雖無直接關係，卻可透過滿意度間接影響持續使用意圖，而其中滿意度是影響持續使用意圖最重要的因素。

The research investigates the factors influencing users' intention to continuously adopt information systems. A continuous usage intention model is constructed using internet blackboard and portal site as sample systems; cross model validation is done to test for multi-group differences between samples. Research findings in cross sample validation show that when either the calibration sample or validation sample is used in the baseline model, both models have cross sample properties, indicating that the model can be applied to different information systems. Constructs in the model include confirmation, satisfaction, perceived usefulness and perceived ease of use (as predictors of continuous adopting intention). Confirmation is observed to have a positive effect on perceived usefulness and perceived ease of use; and although confirmation is found to indirectly affect satisfaction through perceived usefulness and perceived ease of use, it has no direct effect on satisfaction. Perceived ease of use has a positive effect on perceived usefulness, while perceived usefulness has been found to influence satisfaction. Although perceived usefulness has no direct effect on continuous usage intention, it has an indirect effect through satisfaction. Satisfaction plays a major role in predicting user's continuous usage intention.
