本研究主要是運用科技接受模式，探討消費者對EZTABLE訂餐系統的接受行為，除了知覺有用性與知覺易用性之外，本研究加入知覺信賴性一併探討這些變數對使用意向的影響，同時以網路外部性作為外部因素，了解其對網路訂餐系統接受度的影響。本研究的研究對象是曾使用EZTABLE訂餐系統的顧客，採用便利抽樣蒐集樣本資料，問卷是以網路問卷的型態發放，共回收250份有效問卷。所蒐集的樣本資料運用結構方程式分析以驗證研究假設。結果發現，間接網路外部性與知覺易用性對EZTABLE訂餐系統的知覺有用性均產生正向影響，間接與直接網路外部性對EZTABLE訂餐系統的知覺易用性也都有正向影響。顧客知覺的有用性與易用性對EZTABLE訂餐系統的知覺信賴性分別呈現正向影響。顧客知覺的直接網路外部性、有用性、易用性與信賴性對EZTABLE訂餐系統的使用意向均發生顯著的正向影響，最後，使用者的使用意向對實際使用有顯著正向影響。研究結果顯示知覺有用性與知覺易用性是影響使用意向的關鍵因素，餐飲業者在選擇第三方平台系統時，可評估並選擇系統的功能與服務內容設計完善，使顧客感受到有用以及容易使用的餐飲系統，同時，還需考慮選擇具備網路外部性效果的餐飲資訊系統。

This study investigates consumer acceptance of online restaurant booking system in the case of EZTABLE using the theory of technology acceptance model. In addition to investigating the influences of perceived usefulness and perceived ease of use on consumer adoption of the system, the authors study the effects of perceived trustfulness and network externalities on the acceptance of EZTABLE booking system. A convenience sample of respondents who have used EZTABLE booking system was chosen. A total of 250 questionnaires were collected by online questionnaire. Structure equation model analysis was performed to test the hypothesis. The results showed that both indirect network externalities and perceived ease of use had positive effects on perceived usefulness; both direct and indirect network externalities exerted positive influence on perceived ease of use; perceived trustfulness had positive effect on use intention and was influenced positively by perceived usefulness and perceived ease of use which in turn exert positive influences on use intention. Finally, use intention influenced actual use positively. Perceived usefulness and perceived ease of use are critical factors that influence the adoption of EZTABLE booking system. While choosing the online restaurant booking platform, caterers should choice systems with well-designed system function and service which make customer feel useful and ease of use. At the same time, it is also necessary to consider the selection of online restaurant booking systems that have the effect of network externalities.
