隨著國人的生活型態、消費飲食方式改變，國人的外食比率人口逐年增加，而飲食消費的方式也不再只侷限於實體店面。伴隨著網路的盛行、4G行動通訊的便利與流通，虛擬通路的消費型態逐年上升，飲食消費習慣也因網路的快速發展而有了不一樣的變革，而透過訂餐網站或APP平台訂餐的購買行為也逐漸增加，其中又以Foodpanda、Uber Eats、Deliveroo、有無快送、街口外送等外食訂餐APP平台在臺蓬勃發展。
過去科技接受模式(Technology Acceptance Model, TAM, Davis, 1989)的研究證實外部變數會正向影響知覺有用性及知覺易用性，而知覺有用性及知覺易用性亦會正向影響消費者的使用態度及其意願。本研究以科技接受模式為研究架構，將商品資訊準確性、商品種類多樣性、系統服務介面列為外部影響變數，透過文獻整理設計問卷，來驗證外部變數如何影響消費者使用外食訂餐APP平台。
本研究採用問卷調查法方式執行研究，，採便利抽樣回收352份問卷，剔除無效問卷後彙整250份有效問卷，除驗證過去學者的主張外，更證實外部變數的商品種類多樣性及系統服務介面會正向影響知覺易用性及知覺有用及知覺有用性；系統服務介面會正向影響知覺易用性；知覺易用性會正向影響知覺有用性；知覺易用性及知覺有用性同時正向影響消費者的使用態度；使用態度進而正向影響消費者的使用意願。本研究並藉由有效問卷加以分析國內二大平台業者發現，Foodpanda外食訂餐APP平台及Uber Eats外食訂餐APP平台的使用者分析出的結果證實外部變數中的商品種類多樣性商品多樣性及系統服務介面會正向影響知覺易用性及知覺有用性；系統服務介面會正向影響知覺易用性；知覺易用性及知覺易用性進而正向影響知覺有用性；知覺易用性及知覺有用性同時正向影響消費者的使用態度；使用態度進而正向影響消費者的使用意願。以國內二大平台樣本分析得出相同結果，證實外部變數中的商品種類多樣性商品多樣性及系統服務介面會正向影響知覺易用性及知覺有用性；系統服務介面會正向影響知覺易用性；知覺易用性進而正向影響知覺有用性；知覺易用性及知覺有用性同時正向影響消費者的使用態度；使用態度正向影響消費者的消費者的使用意願。本研究主要研究貢獻為二：(一)提供學術界對外食訂餐APP平台研究之參考；(二)提供外食訂餐APP平台業者及餐飲商家做為網路訂餐平台未來業務發展及推廣之參考。

With the changes of lifestyle, consumption and eating pattern, more and more people will not only shop or order food in store but also shop through internet or smart phone. Base on the research we found that the number of consumers who used to have this experience to order food via internet or Food-delivery APP are keep increasing. Some of the Food-delivery APP such as Foodpanda、Uber Eats、Deliveroo etc. are willing to expand and invest their marketing share and win the game.
Past research on Technology Acceptance Model (TAM, Davis, 1989) confirmed that external variables will positively affect the usefulness of perception and ease of use, and the usefulness of perception and ease of use will also positively affect consumers ’ Use attitude and Willingness. This study concentrates on how the effects of perceived usefulness and perceived ease of used affect the consumer's attitude and behavior. In this study, the technology acceptance model is used as the research framework. The accuracy of product information, the variety of products, and the service interface of the system are listed as external influence variables. The questionnaire is designed through the literature to verify how external variables affect consumers' use of food ordering APP platforms.
In this study, and through an effective questionnaire analysis, the two major domestic platform operators found that the results of the analysis of users of Foodpanda's external food ordering APP platform and Uber Eats external food ordering APP platform confirmed that the variety of products in external variables will positively affect perceptual usability and perceptual usefulness ; system service interface will positively affect perceptual usability; perceptual usability and thus positively affect perceptual usefulness; perceptual usability and perceptual usefulness also positively affect consumers' attitudes to use; use attitude positively affects consumers' willingness to use. The same results are obtained from the sample analysis of the two major domestic platforms, confirming that the variety of commodities in the external variables will positively affect the perceived ease of use and perceived usefulness; the system service interface will positively affect the perceived ease of use; positively affect the usefulness of perception; the ease of perception and the usefulness of perception positively affect the attitude of consumers; the attitude of use positively influences the willingness of consumers to use. The main research contributions of this research are two: (1) To provide academic reference for the research on the APP platform for external food ordering; (2) To provide APP platform operators and catering merchants as the reference for the future business development and promotion of the online ordering platform.
