Automatic identification method and device for enterprise tax-related risk based on neural network

The embodiment of the invention provides an enterprise tax-related risk automatic identification method and device based on a neural network. The method comprises the following steps: acquiring a data set of tax-related risk indexes of enterprises with different risk levels; constructing a neural network model according to the tax-related risk index, and initializing the weight of the tax-related risk index of the neural network model through a particle swarm algorithm; inputting the data set and the risk level of the corresponding enterprise into an initialized neural network model for training; obtaining a tax-related risk index of a target enterprise, inputting the tax-related risk index of the target enterprise into the model, and obtaining an enterprise risk level corresponding to the tax-related risk index of the target enterprise through the neural network model; and outputting the enterprise risk level of the target enterprise. By adopting the method, the accuracy, high efficiency and timeliness of ta
