The invention provides a big data fitting-based radio wave propagation simulation method and device, and the method comprises the steps: determining all influence factors affecting radio wave propagation, obtaining the environment data of a current scene of to-be-fitted radio wave propagation, and determining vectors corresponding to all influence factors and vectors representing the current scene; constructing a radio wave propagation model; training the radio wave propagation model by using training data to obtain a trained radio wave propagation model; and inputting the vector corresponding to each influence factor and the vector representing the current scene into the trained radio wave propagation model to obtain the propagation loss of the input radio wave in the current scene. The method is higher in precision, higher in calculation speed and wider in application range of radio wave propagation.
