資訊系統之成效攸關組織運作，然而過去的文獻多著重於探討資訊系統導入，容易去忽略導入完成之後續使用是否適應組織需要，是否對使用者產生價值等議題。基於此，本研究希望以組織層面與個人層面的跨層級觀點，探討影響資訊系統使用之關係。本研究以33家組織為研究對象，受測對象包含組織內部一般使用者與資訊部門員工，共蒐集了456份的實徵資料，含作業型資訊系統使用者344人，資訊部門人員112人。本研究採用驗證性因素分析檢驗資料與階層線性模式 (Hierarchical linear models, HLM) 檢定研究假設。 本研究發現系統品質 (System quality) 以及個人收益影響 (Benefit of individual impact) 皆正面影響使用系統之感受價值以及使用者滿意度；個人負擔影響 (Load of individual impact) 則負面影響感受價值以及使用者滿意度；另外，感受價值還受到電腦自我效能 (Computer self-efficacy) 之正面影響；系統品質調節個人收益影響對使用者滿意度的影響，資訊品質調節個人負擔影響對感受價值的影響。據研究結果本文提出建議與未來方向，以提供組織管理者與學術上參考。 The information systems have a great impact on organizational performance. The existing literature, however, has focused on the implementation of IS, while many issues regarding the post-implementation use of IS remain unexplored. This study proposes a research model that integrates factors at the individual and organizational levels to explain the post-implementation use of IS. The model was tested with a survey design. Four hundred and fifty-six subjects from 33 organizations participated in this study, including 344 IS users and 112 IS department employees. The confirmatory factor analysis indicates that these data are fine. The analysis using HLM shows that system quality, and individual benefits of using the IS are positively correlated with perceived value and user satisfaction. Besides, the perceived value is affected positively by computer self-efficacy. The individual load of using the IS negatively correlates with perceived value and user satisfaction. The results also indicate that the system quality moderates the relationship of the individual benefit with user satisfaction, and the information quality moderates the relationship of the individual load with perceived value. Finally, theoretical and practical implications are discussed.
