In this study, we investigated the status of skill mismatch among young wage workers and examined related factors. We measures the skill mismatch with the improved reliability and examined the relationship between personal characteristics, wage and job satisfaction, job commitment, and job characteristics related to skill mismatch. The higher the educational attainment, the shorter the work experience, the more likely it is the skill surplus, and the skill surplus group showed the lower job satisfaction, organizational commitment, job stress and wage. Skill shortage group showed lower job satisfaction but higher job stress and less feedback and autonomy in the task process than the skill matching group.
