Abstract: The matter-element extension model is used to expand the traditional evaluation index system and increase the index of postgraduate social practice ability. The comparative analysis of the postgraduates' competency of representative universities in the middle, east and west regions of our country shows that the two aspects of the flexible use of innovative knowledge and the ability to innovate practice can most reflect the quality education characteristics of the graduate students' innovative ability. This paper provides a theoretical basis for the cultivation of innovative quality of graduates and the improvement of their innovative abilities, which is of great guiding significance for shortening the regional gap in the creative ability of postgraduates in China.

Key words: innovative ability, matter element extension, quality education, evaluation, graduate student
