With the great changes of the media ecology, information chaos makes the social information ecology in a state of disorder with increasing entropy. At the same time, there are few dynamic evolutionary mechanisms of information disorder governance in information science. Therefore, it is of great significance to clarify the logic of information disorder governance from the perspective of cyberspace governance. Rooted in the concepts related to information disorder and cyberspace governance, this paper explores the dynamic evolution mechanism of information disorder management from the perspective of "information source-information chain-information flow", integrates actors, interpreters and receivers, and builds a tripartite game model of information disorder based on the perspective of cyberspace governance. The results show that the governance of cyberspace ultimately stabilizes in two states: the conscious state of Internet public opinion and the ideal state of Internet space. The actor's strategy choice is not affected by the intervention cost; When the interpreter's promotion costs increases, the receiver's selection rate slows down. The increase in potential income will change the recipient's behavior choice, and the increase in the probability of being deceived will slow down the choice rate, but will not affect the final result.
