Abstract: In the history of Marxism communication in China, “scientific”factors play an important role for successful communication of Marxism. In the context of contemporary thought and culture of China, Marxism is also considered a kind of science with rich contents and methods. This paper argues that, the scientific factors still play an important role in the contemporary communication of Marxism, but if we will thus simplify the communication of Marxism as science communication, and believe that the “scientific” theory can ensure the audiences to accept naturally, then we will make mistakes of oversimplification in the idea, theory and practice of Marxism communication. Faced the profound changes of social cultural and communication environment, Marxism contemporary communication needs a comprehensive innovation in idea, theory and practice.
