Abstract:This paper first build an assessment indicator system for middle and small business among industries.Then utilizes the investigating data from 800 middle and small businesses in different industries in Anhui Province,divides them into training sample and testing sample,discusses the construction of BP neural network,decides the algorithm of BP neural network,so as to set up the credit assessment model among industries based on BP neural network.After carrying on a demonstrated analysis by inputting the data from some sub-industries in agricultural industry and industrial industry in the year of 2003,and analyzing the simulation result,it points out the reasons to result in the large gap between agricultural and industrial industry,and puts forward the suggestion aiming at the credit construction in agricultural industry.
Keywords:BP neural network  credit assessment  comparative analysis
