Chinese modernization enriches and expands the connotation of modernization, and it is also a continuous and evolving goal of the Communist Party of China (CPC) in the course of the century-long struggle. Over several decades, China has achieved the level of modernization that took developed countries centuries to reach, and has always taken the united front as an important strategic weapon, serving as a vital tool for pooling wisdom and strength. In the new era, as Chinese modernization advances the great rejuvenation of the Chinese nation, the fine traditions of unity and collective endeavor must continue, and the patriotic united front must play an active role. This paper theoretically explores the consolidation and development of the patriotic united front under the perspective of Chinese modernization, interpreting its function from three dimensions - historical logic, practical logic, and value logic. It further analyzes how embedding the theory of the united front into the multi-dimensional framework of Chinese modernization, and demonstrates its multi-value functions in serving and supporting modern national development.
