The present invention relates to a transient electromagnetic apparent resistivity calculation method, a transient electromagnetic apparent resistivity calculation system, a transient electromagnetic apparent resistivity calculation device and a storage medium. The method includes the following steps that: a current time window and the induced electromotive force of the current time window are obtained; and the induced electromotive force is inputted into a pre-established neural network model, so that apparent resistivity corresponding to the induced electromotive force is obtained. Accordingto the training process of the neural network model, a training data set is utilized to train a neural network model to be trained, so that the neural network model can be obtained, wherein the training data set contains induced electromotive forces and corresponding apparent resistivity under each time window. According to the method of the invention, the acquired induced electromotive force andthe corresponding time window thereof are inputted into the pre-trained neural network model; the neural network model performs calculation, so that the apparent resistivity corresponding to the induced electromotive force can be generated; a single-valued function is constructed on the basis of the neural network model; and the corresponding apparent resistivity can be directly calculated throughthe neural network model on the basis of the induced electromotive force, and therefore, calculation speed can be improved.
