The invention discloses a flight ground operation support efficiency evaluation method, and belongs to the technical field of airport operation management. Accurate quantitative evaluation can be performed on flight ground support service quality via reasonably selecting key links of various flight ground support services and weight of each key link. Objective evaluation can be performed on various flight ground supports via using the method. With comparison and analysis of support levels of all airline companies, operation defects currently influencing support operation efficiency are identified and are fed back to all the airline companies so that the airline companies are required to put forward solutions. Policy inclination on aspects of airport time application, airport terminal resource application and the like is given to the airline companies with a ground support evaluation score which is higher than an industry average level. As for the airline companies with the ground support evaluation score which is lower than the industry average level, development of new air routes are limited and flights in the airport are reduced.
