Abstract: Marxist concept of "communication" is not only regarded as an important category of historical materialism theory, but also one of the hot research topics of Marxism. Marx believed that in the natural community, human's practice is a kind of natural perceptual practice. The communication way based on production and labor comes from the objective activities between human and nature. In the abstract-illusory community of capitalism, the alienation of the human relationship leads to the connection between people developed on the basis of money as the intermediary, and the communication way is alienated and abstract on the basis of "capital principle". In the community of freeman association, Marxsit concept of "practical value" covers the original connotation of labor value, and becomes a new carrier of human value. The ways of communication with human free personality as the intermediary makes human value run through all aspects of practice, and the means and purpose are unified. The communication way, which takes human's free personality as the medium, makes human's value run through every part of practice and realizes the unity of means and purpose. Nowadays, the rapid development of the Internet not only changes the way of people communication, but also put forward new challenges. Therefore, it is no doubt helpful for us to reflect on the communication way in the Internet era from the perspective of Marx community.
