Therefore, the author combined the theoretical model to analyze the above game process, gradually explored the evolution mechanism of collective corruption, and suggested to strengthen collective corruption governance from the aspects of corruption investigation rate, restriction and supervise of power, incentive mechanism and whistleblower protection system.
