Improved BP Neural Network's Application in the Bank Early Warning

Franchise value affects bank stability, so this article analyzes of the various factors franchise value, constructs bank stability evaluation system from market-related factors and bank-related factors, based on improved BP neural network constructs early warning model of bank stability, and takes America banks’ data as training samples, takes Chinese Banks’ data as test samples, finds that Chinese bank stability is worth than America bank stability, so it is necessary to take measures to enhance Chinese bank stability.
