本研究主要從行為意向的角度，以LISREL為分析方法，科技接受模式與分解式計畫行為理論為研究基礎，探討�21位中華電信員工採用知識管理系統之影響因素，並比較兩種理論模式。研究結果發現，分解式計畫行為理論在行為意向的解釋力方面並未較科技接受模式有明顯增加。使用者對知識管理系統之影響因素方面，行為意向能有效預測使用行為；態度、主觀規範與知覺行為控制能有效預測行為意向；有用性認知只能間接預測行為意向；易用性認知能有效預測有用性認知；有用性認知與易用性認知能有效預測態度；同儕影響與主管影響能有效預測主觀規範；自我效能與資源助益環境能有效預測知覺行為控制。

Using Linear Structural Relation model (LISREL model) as analysis method and technology acceptance model and decomposed theory of planned behavior as research foundation, this study approaches mainly from the angle of behavioral intention to examine the influential factors of 421 employees adopting knowledge management systems and in the meantime to compare the two method models mentioned on the top. According to the research, there is no, in comparison with technology acceptance model and decomposed theory of planned behavior, apparent increase on the explanatory power with the posterior. On the aspect of influential factors of users toward knowledge management systems, behavioral intention can efficiently predict the usage behavior, while attitude, subjective norm, and perceived behavioral control the behavioral intention. Perceived usefulness can only predict the behavioral intention indirectly, while perceived ease of use can efficiently predict perceived usefulness. Perceived usefulness and perceived ease of use can predict attitude effectively. Both peer influence and superior’s influence can operatively predict the subjective norm. Self efficacy and resource facilitating can predict perceived behavioral control.
