Research On Small And Medium Enterprise Credit Rating Based On Credit Ecology

As is an important part of the national economy, SME is a significant channel to ease employment pressure, and the main to establish the socialist market economic system. Financing difficulty is still the primary factor to restrict the development of SME at this stage, and the main reason for financing difficulty is the problem of SME credit. At present, commercial banks don’t formulate special credit rating system and method for SME, while there are asymmetric information between SME and financial institutions. These factors seriously affect the efficiency of financing and credit assessment of SME, exacerbating the financing difficulty of SME.Firstly, this paper takes the relevant theory as a starting point. According to characteristics of SME and the basic principles of establishing the SME credit rating index system, and reference the credit rating index system at home and abroad, it investigates the credit rating index system for SME in line with China’s national conditions on the basis of analyzing the correlation of the credit risk and the credit ecology. This paper establishes a three-layer evaluation system for SME credit rating from three aspects, such as main solvency, willingness to repay and environment of credit ecology. Secondly,with citing the disposal method of the theory of evidence, we establish the estimating model for SME credit rating on the basis of expatiating the basic concept and character. Finally, taking in a small and medium enterprise of Anhui Province as example, the article has evaluated its credit and uses synthesizing evidence to make the uncertain evidence into a unified reliability. Then we have a scientific and reasonable conclusion on the basis of demonstration, and make an effective analysis on the result. We conclude that, environment of credit ecology is effective, and the theory of evidence can solve the vague and uncertain information of small and medium enterprise credit rating effectively. The method provides a new way of thinking for small and medium enterprise credit rating.
