Information communication by network is by far faster than by any other media in human history. Wherever with Internet connection, information can be delivered and broadcasted. Internet in Mainland China has started very late but developed rapidly. By the influence of contemporary informationalism, China’s open up policy takes information as its matrix to catch up and connect with the world of capitalism. At the same time, Internet has brought great impact on Mainland China: Network is no longer controlled by the communist government. People can establish their own channel for transmitting and receiving information and can form the consensus by linking comments on network. Information transmission on Internet will enforce closed Chinese society open up more rapidly. The ways that people think, growing up experience, and even shopping methods are going to shift. At the same time, the traditional political structure of Mainland China, centralization, is going to transform dramatically.
