This　paper　starts　from　the　analysis　of　the　overall　situation　of　postgraduates＇　innovation　ability　in　our　country,　and　constructs　the　evaluation　index　system.　By　using　the　method　of　multivariate　clustering　analysis,　the　31　provinces　of　our　country　university　innovation　ability　is　divided　into　four　categories,　and　the　regional　differences　are　clearly　defined.　Furthermore,　the　weights　of　each　evaluation　index　are　determined　by　using　the　entropy　weight　method,　and　the　comprehensive　evaluation　results　of　the　innovation　ability　of　graduate　students　are　given.
