Abstract: The iterative evolution of digital technology has not only given rise to a new paradigm in the development of digital capitalism, but also systematically reconstructed contemporary capitalist relations of production, accelerating the transformation of traditional labor forms into digital labor. However, under the deep coupling of digital capital and digital technology, the alienation of digital labor has become an unavoidable core issue in the era of digital capitalism. As a new form of labor alienation, the alienation of digital labor not only perpetuates the core logic of Marx's theory of alienated labor, but also exhibits distinct characteristics of the contemporary era. Its actual symptoms are primarily manifested in four dimensions of alienation: the commodification of digital labor subjects, the concealment of digital labor processes, the instrumentalization of the essence of digital labor, and the estrangement of digital labor relations. Therefore, it is necessary to comprehensively explore the paths of sublating digital labor alienation, to enable labor to truly become a means of human liberation and to promote the free and comprehensive development of human beings. There are urgent needs that, under the scientific guidance of Marx's theory of alienated labor and through a dialectical examination of digital labor alienation, we establish digital labor values to break the nihilistic dilemma of labor value, highlight the humanity of digital technology by leading instrumental rationality with value rationality, transcend the old logic of digital capital to regulate the disorderly expansion of digital capital, and build new digital societal relationships to promote harmonious human-machine coexistence development.
