The invention discloses a spot market clearing method and device considering power generation side same quotation proportion clearing, and the method comprises the steps: solving a spot market clearing model according to basic data, and obtaining a unit combination in each fixed time period; solving a spot market clearing model considering same quotation proportion clearing according to the unit combination in each fixed time period, and obtaining unit output of unit clearing in each time period; solving the node price calculation model according to the unit output cleared by the unit in each time period to obtain a Lagrangian multiplier, and calculating the node price according to the Lagrangian multiplier in combination with the node price calculation formula of the node n in the time period t; the unit combination in each fixed time period and the unit output cleared by the unit in each time period are sent to the AGC for tracking execution; and sending the energy price, the blocking price and the node pri
