Abstract: Amidst the rapid development and refinement of digital technology systems, capitalist communication practices, centered around information production, transmission, reception, and interpretation, have undergone profound transformations. The communication system notably demonstrates extensive economic attributes that transcend mere information exchange and ideological realms, increasingly assuming a more critical economic function within contemporary capitalist modes of production. From a politicaleconomic perspective, the capitalist digital communication system fulfills its economic roles within the structure of capital accumulation through five distinct mechanisms: material production, immaterial production, capital circulation acceleration, the intensification of exploitation and inequality, and the reproduction of mainstream ideologies. The Western digital communication system remains incapable of overcoming, and will continue to exacerbate, the inherent contradictions and crisis tendencies embedded within the modes of capitalist production.

Key words: digital communication system, economic function, mechanism of action, contradictions and crises
