外送平台的快速發展改變了消費者的飲食習慣，據資策會產業情報研究所（MIC）統計，在2022年台灣已有72%的消費者使用過外送服務。而外送平台產業的競爭也越來越激烈，因此如何有效提升消費者滿意度與使用意圖，成為外送平台發展的關鍵。關於外送平台中消費者滿意度的因素，在過去大量的被研究過，許多文獻也探討了消費者在外送平台中的行為，然而對於外送平台的服務範圍的劃分則較少被探討。為了解外送平台劃分服務範圍與消費者行為意圖的關係，本研究延伸科技接受模型(TAM)進行分析，探討服務範圍與消費者方便性和有用性之間的關係。此外，本研究從餐點多樣性的角度出發，探討餐廳數量和餐點款式對服務範圍與消費者方便性和有用性之間的關係的影響。
本研究以線上問卷進行樣本蒐集，並透過一般線性迴歸進驗證研究假說。從實證結果發現，外送平台設定的服務範圍與消費者方便性和有用性之間呈負相關，同時方便性和有用性與行為意圖之間呈正相關。然而，當受到餐廳數量和餐點款式的調節效果後，會正向調節服務範圍與方便性之間的關係。而雖然餐廳數量和餐點款式對服務範圍與有用性之間的調節效果不顯著，但本研究的實證結果顯示，餐廳數量與餐點款式會正向的改善服務範圍與有用性之間的關係。本研究的發現提供外送平台劃定服務範圍時參考的實務建議，也將服務範圍的概念納入外送平台領域的學術研究之中。

The rapid development of food delivery platform has changed the dining habits of consumers. In 2022, according to the analysis by Market Intelligence & Consulting Institute, over 72% of consumers in Taiwan have used food delivery service before. Also, the fierce market competition in the food delivery industry making it important for these platforms to raise customer satisfaction and behavioral intention. Many researches focused on these topics and about the consumer behavior on food delivery platforms. However, few research were done regarding the boundary set by the food delivery platform. In order to know the relationship between boundary and behavioral intention, this research extends the Technology Acceptance Model to find out the relationship between boundary and convenience as well as usefulness. In addition, from the perspective of menu diversity, this study examines the impact of the number of restaurants and different types of meals on the relationship between boundary and convenience as well as usefulness.
This research adopts an online survey to collect samples, and ordinal logistic regression has been used to verify the hypothesis. Consequently, there is a negative correlation between boundary set by the food delivery platform and the consumer convenience and usefulness. In addition, there is a positive correlation between consumer convenience and usefulness with behavioral intention. However, when the amount of the restaurants and the types of meals are changed, the relationship between boundary and consumer convenience will be positively adjusted. Although the adjusted effect on usefulness is not significant, the amount of the restaurants and the types of meals still positively adjusted the relationship between boundary and usefulness. The findings of this study provide practical advice to food delivery platform for setting boundary. Also, this research incorporates the concept of boundary into the academic research of food delivery platform.
