Exploring　the　driving　mechanism　of　college　students＇　innovative　behavior　plays　an　important　role　in　accelerating　the　current　cultivation　of　talents　in　colleges　and　social　development.　Based　on　the　results　of　in-depth　qualitative　interviews　with　22　Chinese　college　students,　this　study　adopts　the　procedural　grounded　coding　method　to　summarize　the　pyramid　model　of　college　students＇　innovative　behavior　in　the　three　dimensions　of　innovative　motivation,　innovative　cognition,　and　innovative　behavior,　and　found　that　the　factors　driving　college　students＇　innovative　behavior　are　mainly　autonomy　and　material　factors,　with　motivational　and　mandatory　factors　supplementing　them,　while　college　students＇　innovative　behavior　satisfy　the　needs　for　autonomy,　competence,　and　belongingness.　The　results　broaden　the　current　theoretical　research　related　to　college　students＇　innovation　and　are　of　great　practical　significance　in　guiding　the　cultivation　of　innovative　talents　in　colleges　and　universities.
