The research methods such as Q type cluster analysis， contrast analysis and so on are used to conduct multiple dimensions analysis on competitive technical level of Chinese Mens Basketball Team at RIO Olympics Games， and the analysis shows that the 12 teams of mens basketball at Rio Olympics can be divided into four grade groups， that Chinese Mens Basketball Team is located at the fourth level， that the gap between the Chinese Team and the world strong teams becomes bigger and bigger， and that offensive and defensive technical indicators of Chinese Team overall lag behind the competitors. The author suggests that Chinese mens basketball players should relocate themselves in the preparation of future matches， must be conscious for the gap between them and the players of Europe and the United States， and highlight the improvement of offensive ability by strengthening the training. China should take CBA League construction as the core to really train the Chinese basketball players.
