The embodiment of the invention provides an ozone pollution source identification method and system based on satellite remote sensing, and the system comprises 1) a tropospheric ozone profile inversion module which inverts a tropospheric ozone profile through TropOMI ultraviolet hyperspectral data; 2) a near-surface ozone pollution source indication value inversion module for obtaining the concentrations of near-surface NO2 and HCHO by using TropOMI troposphere NO2 and HCHO column concentration products in combination with an atmospheric chemical model Geos-Chem, and calculating the concentration ratio of the near-surface NO2 to the HCHO to obtain a near-surface ozone pollution source indication value; 3) a near-surface ozone concentration inversion module which integrates NO2, HCHO, ozonemonitoring values of ground national control stations and the like and acquires near-surface ozone concentration through a multiple regression model; and 4) an ozone pollution source target identification module for selectin
