Abstract: The all-round development of Chinese university students is an important mission entrusted to higher education by the nation and the era. “All-round development” requires for the “all-round process” based on “all-round cognition”. Over the past three decades,the Ministry of Education has continuously improved the evaluation index system for higher education,and an independent secondary index “extracurricular activities” was listed in the system in 2013,the effectiveness of which deserves more attention in the academic research. Since 2016,the “University Extracurricular Activity Record” system has been implemented throughout the country,which helps strengthen the goal orientation and process attributes,and make the data accumulation and mining available. The research group selects one university with long-term data of abundant types and complete records as the research object,adopts the cone viewpoint structure,uses quantitative analysis methods,including the multi-valued logit selection model and negative binomial regression,and analyzes the marginal effects between students' learning input in the different extracurricular activity platforms and students' educational output,such as scientific research publication,scholarship grades,and comprehensive evaluation result. It is found that the learning performance of “extracurricular activities” has a positive correlation with the comprehensive assessment performance of the students. The performances in ideological guiding platform and the general education platform are most positively related to educational outputs. The international learning platform can promote the students' grades of College English Test Band 4 and Band 6. The campus culture platform has a crowding effect on student scholarships. The effect of club activity platform and employment platform on educational output is not significant. Therefore,the research group put forward three suggestions for functioning the extracurricular activities better in talents training: to enhance the relevance and construct a remarkable interactive mode of co-education;to strengthen the traction and establish a scientific and reasonable system;and to make good use of resources and improve the use efficiency of external resources in the extracurricular activities.

Key words: extracurricular activities, learning linkage, talents training
