The Research On Credit Rating Of NEEQ Enterprises Based On BP Neural Network

National Equities Exchange and Quotations(NEEQ)set up a specialized platform for the unlisted joint-stock companies to circulate stock,to strengthen the credibility of listed company and optimize the governance structure of listed company.NEEQ not only provide the opportunity for more high technology and high growth companies to circulate stock,but also adhere to provide a financing platform for the middle,small and mini-companies,trying to solve the problem of financing difficulties.Because of the existence of NEEQ,the financing mode of high-tech enterprises is not limited to bank loans and government subsidies.And it promotes the private placement of listed companies.In recent years,the numbers of listed companies have increased steadily to tens of thousands.NEEQ has become an important part of China's capital market.Considering the unique characteristics of NEEQ and starting from the credit rating theories,this paper constructs the theoretical framework,analyzes the influencing factors,selects the evaluation indexes and verifies the accuracy of the model to study the credit rating of NEEQ in depth.This paper selects 2016 three new board in two different industries as two experimental groups,with the current enterprise credit rating standards as the theoretical foundation,the dynamic evaluation index system of innovation as the basis,to create a new set of three new board enterprise credit rating index system model,a total of 19 indicators,from different aspects.Detection of three new board companies.This paper selects two different industries of NEEQ in 2016 as two experimental groups,on the basis of the current enterprise credit rating standards as the theoretical foundation and the dynamic evaluation index system as the innovation,from two aspects of qualitative and quantitative,to create a new set of credit rating index model of NEEQ,a total of 19 indicators,from different aspects to test NEEQ.According to the certain rule,each company of selected two industries is scored.Thereby the companies were divided into different grades.The rating of NEEQ by Zhongping Credit,the independent third party rating agencies as the standard of this article.At the same time,the method of BP neural network is introduced to verify the accuracy of the index system.Through the experimental study of two industries in NEEQ,we find that NEEQ credit rating index system model has high accuracy,and it can make an accurate rating for NEEQ.This paper studies the credit rating of the new board of enterprises,on one hand to provide the basis for commercial bank loans,on the other hand,for investors to show by credit investment enterprises in the objective angle,reduce their investment risk.This paper studies the enterprise credit rating of NEEQ,on one hand,to provide the basis for commercial banks to loan to enterprises.On the other hand,it shows the credit situation of enterprises for investors in the objective angle,reducing their investment risk.
