Abstract: To improve the employment quality of students in higher vocational colleges, it is necessary to break through the traditional extensive management mode and turn to data-driven precision services. From the perspective of system theory, this paper constructs a four-dimensional accurate employment model including “demand identification - precise assistance - dynamic management - feedback and improvement”, and discusses the synergistic mechanism of each link and its promoting effect on employment. The research shows that by integrating educational ecological elements and optimizing resource allocation, the model can significantly improve employment matching degree and career stability, and provide theoretical support and practical path for vocational college employment service system reform.
