Abstract: The discourse power of network ideology affects the domination power and ideological security. With the rapid development of new media and the emergence of many discourse subjects, the mainstream ideology of the network is faced with adverse effects such as information fragmentation, pan-entertainment of expression, "equal rights" of discourse, and stratification of communication, which weakens the authority of mainstream ideological discourse. Therefore, in order to strengthen the foundation of ideology and regime security and to facilitate the great rejuvenation of the Chinese nation, it is necessary to improve the discourse power of Internet ideology, focusing on issues of "who to say", "what to say", "how to say", "to say to whom", "where to say". To solve these problems, we must take measures to establish discourse subject, innovate discourse content, blend discourse media, enhance discourse orientation, and to expand discourse space so as to enhance the discourse competence, persuasion, communication power, cohesiveness, and international influence of network ideology.

Key words: ideology, network ideology, discourse power, focal point, ideological security
