Abstract: The purpose of this paper is to explore a new approach to solve the problem of optimizing the allocation of university aid resources, then propose a grey relational model of aid supply-need precise matching. The conceptual connotations of precise aid and the process of need-oriented aid supply-need precise matching have been introduced at first. Then using the basic idea of grey relational analysis, the definition of supply-need matching grey nearness relational grade is proposed, and the steps of aid supply-need precise matching grey relational model are given. Finally, the constructed model is used to explore the problem of matching decision-making between aid recipients and aid resources, and differentiated aid strategy that effectively meets the needs of students and efficiently utilizes aid resources is given. The validity and rationality of the model are verified. The research shows that the grey relational model of aid supplyneed precise matching can be used to describe the precise matching problem between aid recipients and aid programs. It enables the optimal allocation of aid resources and the maximum satisfaction of aid needs to promote the organic integration of poverty alleviation and talent development. It can provide the decision-making basis and methodological support for the university aid administration, and have certain practical value. The model adheres to the student need-oriented configuration of aid programs, and it can form a differentiated aid strategy that effectively meets the needs of students and efficiently utilizes aid resources. This study provides a new perspective and a new way to solve the optimal allocation problem of aid resources for university students. It can provide the decisionmaking basis and methodological support for the university aid administration.
