本研究之目的在以科技接受模式來探討消費者對光纖寬頻網路使用行為意向之影響因素為何，並驗證「系統品質」及「電腦自我效能」的外部效果。本研究採結構方程式模式進行假設驗證並分析模式路徑關係。另一方面，亦針對已裝設與未裝設光纖寬頻網路的消費者做分群，以探討其對研究模式之差異。本研究以中華電信北區分公司的客戶為例，針對有使用寬頻網路的使用者進行問卷調查。經由結構方程模式進行驗證，結果發現本研究模式中的路徑關係均達統計顯著性，且系統品質與電腦自我效能對於科技接受模式有顯著正向的影響。因此，本研究認為科技接受模式確實能適用於解釋光纖寬頻使用者的行為意向。此外，分群後的模式驗證結果發現兩群樣本確實存在部份差異。最後依據研究結果，提出管理意涵與後續研究建議之討論。

The purpose of this research is to use technology acceptance model (TAM) to explore the antecedents of fiber to the building (FTTB) user’s behavioral intention. This study also tests the external effects of system quality and computer self-efficacy. We apply the structural equation model to test the hypotheses and the relationships in the research model. On the other hand, the difference between the two sample sets which were divided by using or not using FTTB is also explored. We took the Chunghwa Telecom Northern Taiwan Business Group as an example. The data was collected by questionnaires to CHT’s users who had the experience of useing broadband before. After model fitness testing by SEM.The results show that all relationships in the research model are statistical significant. It indicates that the system quality and computer self-efficacy have positive and significant influences on TAM. Thus, we think that TAM can be use to explain the FTTB user’s behavioral intention. Besides, there are some differences between two groups after making further model test and path analysis. Finally, this study discussed the managerial implications and offered suggestions for the future researches.
