%X Bilevel programming models can efficiently describe the management decision system with multilevel. In this paper, we introduce a class of quadratic bilevel programming models, which have extensive representativeness, and discuss their geometric characteristics. In the end, we give optimality conditions of the quadratic bilevel programming models.
