Abstract: College students' practice works competition can cultivate students' innovative consciousness, practical ability and practical ability. In order to explore the influence of different factors on the achievements of college students' practical works, the grey entropy correlation analysis method was used to calculate the grey entropy correlation degree of the winning achievements. The results show that the most significant and least significant influencing factors are the stylistic activities and the number of failed courses, which show that the practical work competition pays more attention to the comprehensive quality of college students. The significance of the influence of different factors on the performance of the achievements has changed, but the most and least significant factors in the last three years were the recreational and sports activities and the number of failing grades, which showed a stable trend. The influence of the factors related to the academic performance on the performance of the competition has gradually decreased, which indicates that the competition has higher and higher requirements on innovative thinking, practical ability and other qualities.
