The invention provides an aircraft position prediction method based on air-ground track information sharing, and belongs to the field of air traffic management, and the method comprises the steps: firstly, in a flight plan stage, a ground control center obtains basic data of all airplanes in a control range; for a single aircraft, predicting and generating an initial four-dimensional flight track of the aircraft; in the preparation stage before takeoff, an airplane and a ground control center establish air-ground data link connection, expanded flight profile data calculated by an airborne system is shared through ADS-C, an initial four-dimensional flight path is corrected based on the data, and a reference four-dimensional flight path is generated; in the flight process, the ground control center receives the ADS-C data and the ADS-B data from the aircraft at the same time to achieve judgment of air-ground flight path consistency, and if the consistency condition is not met, dynamic correction is conducted on
