To accelerate the development of philosophy and social sciences with Chinese characteristics is, in the final analysis, to build China's independent knowledge system. Sinicized and epochalized Marxism is the most important Chinese independent knowledge system, which constitutes the overall soul of contemporary Chinese independent knowledge system. Only by implementing such a soul in the construction of specific independent knowledge systems in different fields and disciplines can we truly construct an internal unified, comprehensive and complete independent Chinese knowledge system. Contemporary Chinese journalism, as a supporting discipline in the discipline system with Chinese characteristics, plays an important role in the construction of the independent system. The foundation and necessity of constructing the independent knowledge system of contemporary Chinese journalism have logical priority in all the problems concerning the construction of the independent knowledge system. Proposed in this paper, the independent knowledge system of contemporary Chinese journalism is the facts and experience of China as the foundation, based on knowledge system of Chinese marxist concept of news for the soul, is standing on the position of China, solve the problem of Chinese news, can meet the needs of the development of Chinese news and serving the Chinese characteristic socialist journalism knowledge system, It is a knowledge system that serves the development of Chinese modernization in the form of news, an open knowledge system that carries out extensive exchanges and constantly develops and improves, and a knowledge system that explicitly recognizes and pursues the organic unification of epistemology and axiology. The construction of independent knowledge system is based on and necessary in the following aspects: each country, nation and society has its own relatively special historical situation, civilization characteristics and cultural traditions, its own contemporary objective reality and development level, and its own future blueprint and ideal pursuit; Only by actively constructing independent knowledge system can we solve our own problems effectively and meet our own development needs. Compared with the "independent" knowledge system, the other knowledge system has more reference value.
