Abstract:The essence of discourse is the rule of ideology, so the discursive power concerning value is but a kind of right to pass value concept,that concerning politics a political power and control force, that concerning practice a kind of right to lead people to know the world and shape the world,and that concerning society a right to maintain the legitimate interests. The key to build Marxist ideological discursive power is to target at problems, but the premise to do so is the builders’ confidence in theory and their own might. To build Marxist ideological discursive power, we must build a rational discursive system, set up the era theme and promote the popularization of Marxism.
