The invention relates to a stage capable of rising and falling at three levels. The stage comprises a hydraulic device, a supporting device, a guide device and a lifting device. First connecting plates and first supporting plates are distributed on the outer wall of a first supporting frame at intervals. A first hydraulic cylinder is hinged to each first connecting plate. The other end of each first hydraulic cylinder is hinged to a stand column. Second connecting plates and second supporting plates are distributed on the outer wall of a second supporting frame at intervals. A second hydraulic cylinder is hinged to each second connecting plate. Third connecting plates and third supporting plates are distributed on the outer wall of a third supporting frame at intervals. A third hydraulic cylinder is hinged to each third connecting plate. One side of a leveling hydraulic cylinder is connected with an oil inlet pipe, and the other side of the leveling hydraulic cylinder is connected with an oil conveying pipe. A first limiting stopper, a second limiting stopper and a third limiting stopper are correspondingly fixed to the lower portion of the first supporting frame, the lower portion of the second supporting frame and the lower portion of the third supporting frame respectively. The stage conditions are upgraded, the stage facilities are enriched, a flexible stage environment is provided for some special performances, and the ornamental value of the performances is increased.
