An empirical study of innovation education model with a related survey of subject competitions in Chinese colleges and universities was carried out, and the results of which was presented in this paper. Under the paradigm of the agility theory, a dynamic and cross-level 'enhancing comprehensive ability through subject competitions' innovation education theoretical model was constructed and examined by using structural equation modeling. A total of 350 English majors and 50 social personnel participated in this study by using the method of multi-layer random sampling and cluster sampling. 382 valid questionnaires were used for the data analysis. Data collected were analyzed by internal consistency reliability analysis, exploratory factor analysis, and confirmatory factor analysis. The empirical results suggest that under the guidance of the agility theory, the six links have significant positive impact on the innovation education and ultimately enhance students' comprehensive ability through subject competitions.
