Abstract: Time as a philosophical category has long been concerned by people. Marx understood time from practice and regarded it as human's active existence, development space and life scale. On this basis, we analyze and reveal the exploitative nature of the capitalist mode of production on time. In the context of today's digital capitalist relations of production, there is a new alienation of human active existence, blurring the line between labor and leisure. The development space of human is further compressed, and the one-sided emphasis on the current consumption concept dissipates the scale of life, which reflects that the time exploitation of digital capitalism is further aggravated. In response to the global expansion of digital capitalism, we must vigorously develop digital economy to expand development space, constantly improve the national governance ability to overcome digital alienation, and strive to change the subject's concept of time to construct the scale of life, so as to transcend the logic of capital time exploitation and restore free time to the people.

Key words: time category, digital capitalism, exploitation of time, free time, digital alienation
