An optical satellite remote sensing transfer calibration method based on near-space aerostat, including: performing a temporal-spatial matching between first observation image data of a target region collected by a benchmark radiometric payload and second observation image data of the target region collected by a satellite-borne payload, to obtain a plurality of matchups of observation image data (S); obtaining an average radiance of the benchmark radiometric payload from a plurality of first observation image data (S); obtaining an average DN captured by the satellite payload in the target region from a plurality of second observation image data (S); obtaining a matching radiance for an observation band of the benchmark radiometric payload corresponding to the satellite payload based on the average radiance of the benchmark radiometric payload (S); and obtaining a calibration coefficient of the satellite payload based on the matching radiance and the average DN (S).
