First, the research on vocational plateau in China started late, with few research results and many foreign theories, but there is little empirical research on vocational plateau. This study constructs a structural relationship model among career plateau, job satisfaction and job performance, and takes job satisfaction as an intermediary variable to study its influence on the relationship between career plateau and job performance, which enriches the empirical research on career plateau in China.

The subjects of this study are employees of enterprises in China. Under the social and cultural background with China characteristics, there is not much research on the career plateau image of enterprise employees, especially on the career plateau, job satisfaction and job performance of enterprise employees in China. This study expects to put forward specific suggestions to effectively alleviate or avoid the problem of career plateau, improve employees' job satisfaction and performance, and provide basis and guidance for human resource management. I solemnly declare that my dissertation is the result of independent research under the guidance of my tutor. This article does not contain any research results published or written by other individuals or groups, except those cited in the article.
