This study aims to explore the relationship between employment positions and education for students majoring in mechanical manufacturing and automation at vocational colleges. It analyzes the intrinsic connections between teaching content, methods, and students' employability from a theoretical perspective. Employing literature review and theoretical analysis, the research constructs a theoretical framework encompassing four dimensions: teaching objectives, content, methods, and student employability. Under this framework, the study delves into how teaching objectives influence content selection, how content is transformed into employability through various teaching methods, and how these abilities are manifested in the job market. The findings suggest that vocational colleges should consider industry demands and future job characteristics when designing the curriculum for mechanical manufacturing and automation, optimizing content and methods to enhance students' professional skills and overall quality, thereby boosting their employability. Additionally, the study highlights that the close integration of education and employment aids in increasing student employment rates, and reflects the adaptability of vocational education to socio-economic development needs.
