### Abstract

This paper focuses on the analysis of bank failure causes i.e. prediction. Based on the neural network model, we use principal component analysis and fuzzy C-mean cluster analysis algorithm to achieve the evaluation of bank efficiency, the mining of bank insolvency causes, and the prediction of bank failure risk. By considering the literature search and production method together, we classify the 64 indicators of the indicator set into input indicator layer and output indicator layer. In the process of data analysis, we found that some of the higher weights do not objectively reflect the causes of bank failures. In order to avoid simply selecting 5 indicators from the 64 indicators, we used principal component analysis to reduce the dimensionality, set the number of extracted factors to 5, and consider the bank failure factors comprehensively through the 5 selected principal components, and calculate the percentage weights of the eigenvalues calculated for each principal component each year to complete the calculation of each bank's score. Whether a bank fails or not has a strong nonlinear relationship with 64 indicators, and considering that some of the data present exponential relationship, logarithmic relationship, less pure linear relationship between the data, and the indicator dimension is too large. Therefore, we decided to build a model based on BP neural network model, and continuously reduce the error by forward, backward transmission.
