Abstract: As the "comer stone of the market economy", the anti-monopoly law enjoys its general application. And as big business, the professional sports should also be regulated by the anti-monopoly law. The anti-monopoly law doesn't grant exemption to the professional sports. The main anti-monopoly issues in this field include cartels among owners, abuse monopoly position, concerted refusals to deal, mergers and acquisitions, administrative monopoly and etc. Because the very nature of the business requires both competition and cooperation, the anti-monopoly law should apply the rule of rationalization upon the combinations between/among competitors.
