The author carried out a Rank Sum Ratio(RSR) analysis on the competition abilities of Chinese university men’s basketball team in World University Games, and revealed the following findings: as for team China, its offense ability’s RSR value was 0.302 0, belonging to a class D team, ranked 20 th in the world; its defense ability’s RSR value was 0.504 3, belonging to a class C team, ranked 13 th in the world; its comprehensive offense and defense ability’s RSR value was 0.326 1, belonging to a class D team, ranked 15 th in the world. Team China is a typical offense and defense unbalanced team; offense ability on the low side is an important factor for causing game losing, specifically embodied in that its field-goal percentage and offensive rebounds were highly significantly different from those of its opponents(P<0.01). The author proposed that team China should further enhance its offense ability, especially enhance its high shooting and rebound securing abilities, strengthen defense, control point loss, boost the balance development of offense and defense abilities, so as to comprehensively enhance its competition abilities.
