Abstract: As shown in previous researches, there are certain differences in the sports life of social members at various stratums, social members at different stratums seem to have “dedicated” sports life contents, and “sports stratification” seems to be the essential summarization of relations between sports differentiation and social stratifi-cation. However, using “sports stratification” as a research framework without verification will lead us to an incor-rect orientation of relations between these two concepts. The author dissected relations between these two concepts via empirical study, and revealed the following findings: there are 3 types of relations between sports differentiation and social stratification, namely, uncorrelated relation, positive relation, and multivariate relation; sports life areas corresponding to different relations are different.
Key words: sports sociology；sports differentiation；social stratification；sport stratification
