Private education is an integral part of the socialist education cause. Teachers born in the 1980s and 1990s are the mainstay of the teaching team. They have strong scientific and innovative literacy and ability, and are the "new generation" group in the teaching team. In the development process of private universities, due to factors such as instability and low level of social security, there is a high turnover rate of teachers, as well as an unstable and insufficient teaching staff. Helping private universities improve the stability of their teaching staff and organizational identity has become an urgent problem that private universities need to solve. Based on self-consistency theory and social identity theory, this study constructs a dual path hypothesis model for the impact of work values on job performance. In the survey of teachers from three representative private colleges in Yunnan, to avoid homologous variance, two surveys are conducted at two time points, 253 valid samples of new generation teachers are successfully matched, and confirmatory factor analysis and hypothesis testing are conducted using statistical software such as Amos and SPSS. The results show that work values have a significant positive impact on job performance, professional identity, and organizational identification. Professional identity and organizational identification play a dual mediating role between work values and job performance. From the management level, it is proposed that private colleges and universities should respect the work values of the new generation teachers, select teachers with positive work values, create a good organizational environment, and improve the teacher incentive mechanism, to enhance the professional identity and organizational identification of the new generation teachers, thereby improving the job performance of the new generation teachers, and stabilizing the teacher team.
