Abstract: To advance the discourse power building of college ideological and political theory course, we must grasp its connotation comprehensively. The discourse power of college ideological and political theory course could be divided into subject, textbook and teaching discourse power, which are different and relatively independent among their generative process, construction subject, essential connotation and fundamental requirement. On the other hand, the three powers are closely linked and mutually complementary, during which there are actual cross of different subjects, mutual blending of different processes, inherent consistency of different requirements and so on. Therefore, it needs the different links to coordinate with each other, support each other and advance wholly.
