In this paper, we surveyed 300 micro enterprises in each main sector and examined the relationship between major factors related to digital transformation using the structural equation model. The main results are as follows: First, the recognition level, technology acceptability, and readiness for digital transformation of micro enterprises were generally insufficient. Second, the effects of technology acceptance for digital transformation on digital transformation willingness and digital transformation readiness on the digital transformation implementation were statistically significant, while the effect of digital transformation recognition on digital transformation willingness was relatively small. Third, the larger the sales volume of micro enterprises, the higher the degree of digital transformation readiness and digital transformation technology acceptance. These results imply that for the digital transformation of micro enterprises, it is important to improve the readiness level such as infrastructure, human resources, knowledge, etc., and increase the acceptability level of technology understanding and technology learning, and pay attention to the sales level of micro enterprises. Increasing awareness of digital transformation alone cannot promote digital transformation, and as the company scales up, the need for digital transformation increases, suggesting that special attention should be paid to digital transformation of micro enterprises with large sales volume
