Abstract: In the digital era, the expansion of digital monopoly capitaldriven by the dual logic of profitmaximization and geopolitical power contestation-poses significant challenges to China's ideological securitythrough capital accumulation, technological empowerment, and international political rivalry. Under the guiseof "technological neutrality," digital monopoly capital penetrates, fragments, and manipulates ideologicaldissemination in China. This article proposes a three-dimensional framework to counter such risks: institutionalregulation, intelligent governance, and civic literacy cultivation. At the level of institutional regulation, Chinashould strengthen antitrust oversight of digital capital, clarify regulatory boundaries for sentiment analysistechnologies, and establish risk classification and collaborative supervision mechanisms. At the level ofintelligent governance, mainstream media must enhance the humanistic and participatory dimensions of publicopinion communication, constructing an intelligent, human-centered, and synergistic discourse ecosystem. Atthe level of civic literacy cultivation, the cultivation of digital citizenship requires tripartite empowerment acrossstate, society, and individual actors, foming a co-govemance framework for digital competence.
