Abstract: This study was designed to investigate the relationship between coach's leadership behavior and team efficiency in Chinese high level university basketball teams. Taking players on the 2015 CUBA teams as subjects,the authors usedthe "Questionnaire on the Relationship between Coach'sLeadership Behavior and Team Efficiency in Chinese High Level University Basketball Teams" as the research tool, and distributed the questionnaires through judgemental sampling. 320 valid questionnaires collected were analyzed and discussed through exploratory factor analysis, Pearson correlation analysis, canonical correlation analysis, and multiple linear regression analysis. The results show that coach leadership behavior is significantly correlated to team effectiveness. multiple linear regression analysis indicates that coach's training and instructionbehavior and reward behavior have the most direct influence on team performance. From the perspective of the I-P-Otheory, coach's professional training and guidance, verbal praise and material rewards play an important role in improving team performance. Empoweringplayers moderate initiative and giving them timely care are indispensable too. Players generally disagree with coach's autocratic behavior, therefore how and when to adopt autocratic behavior in the process of training and games is a question worthy of coach's careful consideration.

Key words: basketball, coach leadership behavior, team efficiency, high-level teams
