Abstract: On the basis of investigating the media discourse texts on Chinese football, this paper analyzed and interpreted the construction of Chinese football discourse space in the dimensions of openness, transparency and public interest, and explored and prospected the development trend of public discourse space in today's Chinese society: (1) Multi-discourse subject actively participates in the practice of constructing Chinese football discourse space through traditional media and network new media, dredges the channels of public discourse expression through the national forum which has no "access control", and fully reflects the openness characteristic of public discourse space; (2) Chinese football is a sports game with the highest transparency of discourse in China, which gives full play to the supervision effect of public opinion in public discourse space, but the process of breaking through the limited topics and discourse forbidden areas is difficult, gradual and tortuous. The agenda setting function of the media plays a "double-edged sword" effect in this process. (3) Discourse discussion on "based on football and beyond football" has risen to the level of issues related to social and public affairs. The construction and development of public discourse space and the promotion of public awareness are interdependent and mutually reinforced, reflecting the ideological concept of "home, country and the world".

Key words: media discourse, discourse space, publicity, Chinese football
