This study verified which attributes affect the satisfaction and reuse intention of delivery applications. We tried to include important differentiating attributes of applications that are currently showing a high market share in Korea (BaeMin, Yogiyo, CoupangEats). We defined the selection diversity for BaeMin, a price discount for Yogiyo, and the accuracy of delivery time and the speed of delivery for CoupangEats as differentiating attributes. In addition, cheapness of delivery cost, pleasure, cognitive effort, and security risk were included in the attributes. Data were collected through a questionnaire to verify the relationship. The result of analysis using Structural Equation Model showed that selection diversity, price discount, accuracy of delivery time, and cognitive effort were significant attributes explaining satisfaction. In contrast, cheapness of delivery cost, speed of delivery, pleasure, and security risk did not show a significant effect. Satisfaction had a significant effect on reuse intention. On the other hand, it was found that consumers who use BaeMin highly evaluated the selection diversity compared to those who did not, and Yogiyo users highly valued price discounts and CoupangEats users highly valued accuracy of delivery time and speed of delivery. This means that the differentiating attributes of individual delivery applications are being accepted by consumers. If so, consumers who use individual applications would have chosen the application because they value the differentiated attribute of the application as more important than other attributes. Therefore, in the case of users of a specific application, it can be inferred that the effect of the differentiated attribute of the application on satisfaction will be higher than that of consumers who do not use the application. The result of the analysis showed that in the case of Yogiyo's price discount, the effect on satisfaction was significantly higher in the user group than in the non-user group. However, the selection diversity of BaeMin and CoupangEats' delivery speed and accuracy showed the same direction as the hypothesis, but it was not significant.
