Ideology is of great importance, especially the network ideology. In the new era, China’s network ideology is characteristic of multi-interaction, communication fluidity and complexity of struggle. Due to capital expansion and lagging of systematic discourse innovation, network ideology is risking easy elimination of its discourse power. In addition, insufficient construction of the national ideological network community worsens the risk. Therefore, it is necessary to speed up the cultivation of compound multi-disciplinary talents so as to strengthen capital supervision, innovate ideological discourse, and consolidate the discourse power of network ideology in multiple dimensions. Also, the new era needs to attach importance to big data technology, enlighten the national network ideological community, and emphasize the socialist core values as the ideological core of the community, improve the construction of the national network ideological community so as to enhance the effective China’s network ideological security in the new era.
