With the arrival of the big data and cloud era,people from real space extend to pseudo space. Pseudo space is a virtual space of symbolic and mimetic,which has profound influence on people's "conceptual world" and "conscious world". The network pseudo space has the duality of "uncontrollability" and "controllability". Ideological governance of network pseudo space should start from the overall layout,improve the mechanism,agenda setting,content construction,environmental construction and others aspects,to ensure the motive power of the subject to participate in governance,mobilize the power source of netizens' participation in governance,enhance the attractiveness of the mainstream ideology,promote the leading force of the mainstream ideology and form the constraining force of mainstream ideology. Finally,it will help to form the composition of the ideological governance forces in network pseudo space and to achieve the "good governance" goal.
