Abstract: At present, sports, as an important part of the national image, has become a showcase of a nation's comprehensive power and an important channel to shape national image. The constructivism maintains that national image is a social relation whose formation consists of three parts, namely, target objects, channel of information communication and cognitive subjects. To shape the national image through sports, a good sports entity is the prerequisite, and a good sports fact in turn needs various channels to be passed to the public before it can be known. When the public receive the related information, their cognitive and emotional system will select the information and store the selected information into their brain, thus a national image is formed. Therefore, to shape the national image through sports calls not only for the construction the sports entity that is in accord with the value of the public but also various media to shape the media image that can be cognized and acknowledged by the public.

Key words: sports, shaping, national image, constructivism, cultural soft power
