Automatic data statistical analysis method

The invention discloses an automatic data statistical analysis method. The automatic data statistical analysis method is implemented by data input modules, data processing modules, neural network training modules and data output modules. The automatic data statistical analysis method includes steps that enterprise operating data are transmitted to the data processing modules by the data input modules; the data processing modules comprise preprocessing modules and neural networks, the enterprise operating data are preprocessed by the preprocessing modules to obtain preprocessed enterprise operating data after the enterprise operating data transmitted by the data input modules are received, the preprocessed enterprise operating data are transmitted to the neural networks, operating data analysis results can be obtained by the neural networks and can be transmitted to the data output modules, and preprocessing includes unified classification on data categories and normalization processing on the data; the neural
