In the early age of the MZ generation, the number of N workers participating in side projects in addition to jobs that earn main income to prepare for retirement is increasing. Some of them are increasingly interested in starting their own businesses as they prepare for retirement. At this point, this study conducted an online survey of the MZ generation among prospective founders nationwide. The collected data were selected and valid 272 copies were obtained and used for analysis. Correlation verification was analyzed using Pearson correlation. As a result of the division, first, autonomy among personal characteristics was found to have a significant effect on entrepreneurship intention. On the other hand, it was found that creativity and conductivity were not significant among personal characteristics. Second, the role model was found to have a significant influence on entrepreneurship intention. Third, among anxiety, workplace anxiety had a significant effect on entrepreneurship intention, but future anxiety was not. In the mediating effect test of entrepreneurship opportunity recognition, the mediating effect of entrepreneurship opportunity recognition was found between creativity, conductivity, autonomy, and entrepreneurship intention among individual characteristics. It was found that there was a mediating effect of entrepreneurship opportunity recognition between the relationship between the role model and entrepreneurship intention. On the other hand, among anxiety, recognition of start-up opportunities was found to have no mediating effect between the relationship between job anxiety, future anxiety, and start-up intention. These findings could present a differentiated perspective on the start-up intention of the MZ generation. In addition, by providing important clues to raising awareness of start-up intention, it will be possible to provide a solution to the development of a program to recognize start-up opportunities for the MZ generation.
