Through literature research and expert interviews, we extract 10 variables influencing the new generation migrant workers' employability, and establish the comprehensive evaluation model of the new generation migrant workers' employability. Using factor analysis, we derive that the model includes three factors: skill literacy, relationship literacy and basic literacy. The weights of each factor are 0.580, 0.244 and 0.174 8, respectively. Skill literacy is affected by skill level, learning ability, career aspiration, ability to analyze problems, physical health status and other factors. Relationship literacy is affected by the sense of teamwork, interpersonal skills, social support and other factors. Basic literacy is affected by educational level, hardworking spirit and other factors. According to the results, we put forth the following recommendations to improve the new generation migrant workers' employability: strengthening the vocational skill training; coordinating the vocational education resources.
