Abstract: According to the statistics of 7 seasons disciplinary cases released on the official website of CBA league, behaviors that destroy the competition order were mostly committed by audience. However, because they are not the objects of association rule management, the association rules and related rules are not directly applicable to the audience. Therefore, the regulation measures that CBA conducts on audience who destroy orders are not effective. NBA is the world's most successful professional basketball league, but still has number of audience violence. But its experiences on controlling the court order and the appeal mechanism, rules and regulations are worth learning.

Key words: professional basketball league, CBA, NBA, audience, court order, behavior regulation, Occupation sports
