As a product of the integration between capital logic and digital technology, digital consumerism is profoundly impacting the value systems of university students. It manifests in four dimensions: the penetration of symbolic consumption, the covert manipulation of algorithms, the virtual distortion of social interactions, and addiction to entertainment consumption. Through reified labels, it deconstructs subject identity; with traffic logic, it subverts aesthetic spirits; by instrumental rationality, it overrides value judgments; and within algorithmic cages, it dissolves critical thinking, plunging students into an alienated predicament of value symbolization, aesthetic vulgarization, utilitarian judgment, and weakened rationality. Through multi-stakeholder collaboration - restraining capital expansion and technological alienation at the societal level, reconstructing consumption critique paradigms in educational domains, reshaping thrifty cultural genes in family spaces, and achieving theoretical awakening and practical empowerment at the individual level - we can demystify the alienation of students' values by digital consumerism, break the hegemony of digital capital over their values, cultivate digitally civilized individuals with rational discernment and value depth, and provide theoretical and practical models for ideological construction in the digital age.
