Abstract:

In this paper,the BP(Back Propagation)neural network theory is applied to forecast taxation after ana’ lyzing the major factors affecting the tax.During the investigation,the original data are preprocessed to meet the re quirements of the study in BP neural network,and a taxation forecasting model based on BP neural network is es tablished.The proposed model is then verified by using actual data and is compared with the traditional statistic model.It is concluded that the proposed model is of hi gh precision and great applicability.

Key words: taxation forecasting, forecasting model, neural network
