Abstract: A common ideological basis exists in Mao Tsetung's methodology of the mass line and Norbert Wiener's theory of both-way communication and modern mode of democratic management. The modern democratic management embodies both Mao Tsetung's thought and Wiener's theory. However,while Mao Tsetung's thought is ignored by Wiener，the combination of Wiener's scientific theory and Mao Tsetung's philosophic thinking is also ignored by innovators of new managing ideology.

Key words: mass line, both-way communication, democratic management
