This study examined the usage status of consumers using B-Mart, a representative quick commerce service in Korea, categorized consumers according to frequency of use, and investigated the effect of perceived risk and fear of COVID-19 on satisfaction by consumer type. For this purpose, an online survey was conducted targeting adult consumers in their 20s and 40s who had B-Mart experience, and a total of 520 response data were collected. The data were analyzed through K-means cluster analysis, chi-square test, ANOVA, and multiple regression analysis using the SPSS 26.0 program. As a result of the analysis, there were three types of consumers according to the frequency of using B-Mart. The first type was heavy users, accounting for 17.3% of the total survey subjects, and it was a group of consumers who used B-Mart more than eight times a month. The second type was medium users, accounting for 27.5% of the total survey subjects, and it was a group of consumers who used B-Mart about once a week. Finally, light users accounted for 55.2% of the total survey subjects, and the frequency of using B-Mart was lower than that of other groups. Heavy users had the highest rate of purchasing goods at B-Mart, followed by medium users and light users. In addition, light and medium users, who use B-Mart at a lower frequency than heavy users, perceived delivery risk at a lower level, and heavy users perceived delivery risk and privacy risk higher. The fear of COVID-19 was also found to be greater for heavy users than light users and medium users. Heavy users showed the highest level of satisfaction, and light users showed the lowest satisfaction. This study is meaningful in that it suggested a way to stably settle in the market in the future by examining the usage status, satisfaction, and perceive risk level of consumers using the quick commerce service, which is growing as a new service.
