The embodiment of the invention provides a day-ahead market clearing method and system with participation of a multi-owner cascade hydropower station, and the method comprises the steps: enabling the cascade hydropower station to obtain the market related information issued by a power dispatching mechanism after the day-ahead market of power spot starts, and declaring the related information; constructing an SCUC/SCED market clearing model containing a downstream power station available power capacity total purchase constraint condition by taking the minimum quoted price total power purchase cost as a target, and carrying out clearing optimization calculation to obtain downstream power station quantity price information; and constructing an output adjustment model, substituting the optimized output of the downstream power station with the limited storage and regulation capability into the multi-period output adjustment model of the downstream power station according to the constraint condition, and carrying o
