Political parties play a central and irreplaceable role in a country's political life as the core force leading national development and guiding social progress. The construction of party images through visual design constitutes not only a key component of the Communist Party of China's public and international image in the new era, but also a core issue in national image theory, attracting growing scholarly attention. As authoritative carriers sponsored by Party organizations to publicize CPC propositions and concepts, party journals are tasked with interpreting the Party's innovative theories, conveying its lines, principles and policies, and guiding social public opinion. Their covers—key "visual windows" for projecting the Party's image—carry distinct political, functional, and aesthetic attributes, and thus play a far-reaching role in shaping and disseminating the Party's image and building public recognition and identity. Current scholarship on party images concentrates primarily in political science and communication studies, focusing on theoretical connotations and communication strategies. Visual studies tend to examine carriers such as logos, publicity posters, and films, while dedicated research on party journal covers—a systematic and politically significant communication medium—remains limited. Moreover, most existing studies on journal covers prioritize aesthetic and technological dimensions, paying insufficient attention to their ideological and political functions, thereby undervaluing the role of party journal covers in party image construction. Drawing on the Party Newspapers and Journals Column of the Qiushi website and the Dengta Party Building Digital Library, this paper selects 150 central and local party journals as a comprehensive and representative sample. It systematically analyzes visual design elements of party journal covers and their pathways of party image shaping across four dimensions: journal name typography, color palette, cover imagery, and layout composition. The findings show that party journal covers reinforce authoritative recognition through the calligraphic and typographic treatment of journal names; convey the Party's red genes and ideological depth through a red-dominated color scheme; balance the Party's authoritative and people-oriented image through the interplay of macro- and micro-narrative imagery; and achieve efficient information communication and aesthetic order through hierarchical layout design. The study offers theoretical reference and practical insights for the visual renewal of party journals and the enhancement of party image in the new era.
