Abstract: As an important component of the socialist market economy, the sport industry's development needs the guarantee of the rule of law. Anti-monopoly Law as an "economic constitution" plays an important role in maintaining the market competition order in our country. The monopoly dispute case among Guangdong Zhu Chao Co. Ltd., Guangdong Football Association and Guangdong Yue Chao Co. Ltd. is the first antitrust case in the sports field of China. The case is not only related to the market competition of sport industry, but related to its system reform. This paper, using the methods of literature review and comparison, makes an in-depth discussion of this case. And then based on the case, it explores the nature of sports associations' identity, their participation in market operation, the sports administrative monopoly, and the sport market competition in China, etc.
