Starting with the difference between play and game, the authors pointed out that scholars in China had mixed up these two concepts, failed to know about the cur-rent state of oversea research, thus put forward some academic viewpoints which were internationally incompatible. The authors pointed out the followings: play and game should be differentiated: animals can play, but only human being can play a game; Huizinga’s game theory was inadequate to rebut the theory of “the essence of competition is game”; the standpoint of anti-essentialism had been refuted by many people, was inadequate to become a stumbling block in the study of the essence of competition. Finally, the authors introduced achievements made by western scholars in play and game research, and pointed out the conditions for a game to turn into a competition.
