近年來，全球美食外送市場持續成長，而台灣龐大的外食族群更是為美食
外送發展提供足夠大量的潛在客群，然而根據市場研究顧問公司凱度洞察調查16~60 歲的台灣民眾中仍有高達 60%未使用過美食外送平台 app，顯示台灣仍有很高比例的人群未曾接觸過美食外送服務，且相較於台灣民眾外食的頻率而言，高頻率的美食外送平台 app 使用者亦不如預期多。

創新抵制心理是造成某項創新採用的進程延緩甚至是失敗的一大原因。而
科技接受模型則常被用於探討科技領域的人類行為意圖。故本研究結合創新抵制理論與科技接受模型，探討以知覺易用性、知覺有用性作為中介時，創新抵制障礙對台灣民眾使用美食外送平台 app 的意願之影響。

本研究針對台灣地區曾使用過美食外送平台 app 或對其具足夠了解的受試者進行網路問卷調查，最終收集有效樣本共計 286 份。並藉由實證發現：
(1)添加知覺易用性作為中介後，原先不對使用意願產生顯著影響的價值障礙，變為負向影響使用意願，並受知覺易用性正向效果削減、
(2)添加知覺易用性或知覺有用性作為中介，都會使得原先形象障礙對於使用意願產生的負向影響有所減弱、
(3)添加知覺有用性作為中介，則會削減原先傳統信念障礙對於使用意願產
生的負向影響。

此外，本研究亦驗證不同特質及使用習慣的人，確實於不同創新抵制障礙的感知有所差異：
(1)男性於價值障礙感知高於女性、
(2)沒有實際操作過美食外送平台 app 的受試者會感知到更高的形象障礙、傳統信念障礙，而使用頻率愈低的受試者也會感知到更高的傳統信念障礙。

In recent years, the global food delivery market has continued growing. Moreover, a large number of Taiwanese like eating out. However, up to 60% of Taiwanese aged from
16 to 60 still have never used apps of food delivery platforms (FDP). Moreover, only 15% of who have using experience are heavy users. That is, Taiwanese do not use apps of FDPs as frequently as their frequency of eating out.

This study combines innovation resistance, which is the main reason of the delay of innovation adoption, and Technology Acceptance Model(TAM), which is widely used to explore human behavior intentions in the field of technology, to explore the relationship between four barriers to innovation adoption (value barriers, risk barriers, image barriers,
and traditional belief barriers) and Taiwanese people’s intention to use the apps of FDPs with the mediating effects of perceived ease of use and perceived usefulness.

The study conducted an online-based structural questionnaire to understand the opinion of Taiwanese people who have used the apps of FDPs or who have enough understanding of the apps. Finally, the study got 286 valid samples from SurveyCake.

The results are below:
(1) Perceived ease of use fully mediates the relationship of value barrier and the intention to use.
(2) The partial mediating effects of perceived ease of use and perceived usefulness both reduce the negative impact of the image barrier on the intention to use.
(3) The partial mediating effects of perceived usefulness reduce the negative impact of the tradition barriers on the intention to use.
(4) People with different traits and differences in usage habits can indeed affect people's perception of barriers to innovation adoption.
