The research results indicate the followings: in recent 32 years, the Olympic medals were distributed only in such a small scope as Guangxi and Guangdong regions in the south at the very beginning, then expended to the middle region represented mainly by Hubei province, showing T shape distribu-tion formed mainly by Sichuan province, Hubei province, Shanghai city and Guangdong province; then, the advantages of the middle region weakened gradually, while the advantages of the east region increased constantly, which formed such a new space structure as the east costal region winning all the medals of the entire country; main factors that affect the evolution of such a space structure are coach resource input and sports fund input, which are the form of quantified expression of sports policies. Related departments should increase their support for sports resources in the middle re-gion, because from the perspective of the structure of spatiotemporal evolution in recent 32 years, the middle region has good sports foundations, and vast development prospect. |
