Abstract: With the rapid development of digital technology and Internet industry, digital labor arises at the historic moment. While providing convenience for people's production and life, digital labor also produces a series of unprecedented digital labor alienation problems. Dissimilation of the relationship between digital workers and their own subject freedom; dissimilation of the relationship between digital workers and digital platforms; the dissimilation of the relationship between digital workers and digital social governance, which has become a new issue that cannot be ignored in the digital era. Using Marx's labor theory of value, it reveals the essence of dissimilation of digital labor, then reconstructs the value subjectivity of digital workers, protects the legitimate rights and interests of digital workers, and realizes the co-construction and sharing of data information.
