Abstract: Digital labor， which has attracted much attention and heated discussion， is the product of the rapid development of artificial intelligence and Internet technology， providing a new path for the current capital accumulation. It means the beginning of the research on the digitalization of Marx's labor theory of value. Taking capital logic of Marx as a clue， this article confirms the theoretical rationality of the existence of digital labor and analyzes the production process of the surplus value of digital labor from the point of data becoming commodities. From two factors of civilization and consumption of capital， it also analyzes and affirms the value and significance of digital labor. In addition， the existence of digital labor is a double-edged sword-a booster to accelerate economic development and industrial transformation， and a catalyst for human alienation and time criticism.

Key words: digital labor, data, capitalization, capital logic
