Research On Simulation Of The Small And Medium-Sized Enterprise Loan Pricing Based On Two-Dimension Rating

Small and medium-sized enterprise(SMEs) characteristics of small size makes it have a certain flexibility in the process of operation, such as it has a little of obstructions when make decision and the decision is more efficiency, and flexibility to enter and exit the market, so it has a special strategic position in the economic development. In a variety of policy guidance, SMEs financing dilemma has certain improvement, but the survey data show that SMEs financing cost is still high, the financing environment is still in a tight situation. In July2013, the people’s Bank of China released loan interest rates in addition to individual housing loan interest rates, which in theory can help reduce the financing cost and solve the financing difficulties of SMEs, but the liberalization of lending rates could reduce the bank’s profit space and increase bank’s risk. However, in order to increase profit space and enhance the core competitiveness of the market, they must seize the potential customers of SMEs who have high risk and more uncertainty. To development the business of SMEs, the main problem of the current commercial bank faced is how to make credit risk rating scientific and reasonable according to bank’s business philosophy and features, and quantify the risk rating results in loan pricing. In this way, they can further to find the effective way to solve the problem of SMEs and achieve the "win-win"between the fact that it under the marketizationm of interest rate as one of the major problems currently faced by commercial banks.To review the existing literature, considering the data availability, credit rating, the qualitative and quantitative index of effective integration and some other factors, the paper adopts five and three grade of triangular fuzzy linguistic scale method to make credit rating of SMEs. In this process, the paper divide credit rating into two angles:short-term manage achievement and long-term development potential, and put bank’s risk attitude together to calculation the expectation of triangular fuzzy, then set the grade of enterprise based on expectation. In terms of SMEs loan pricing, based on the capital asset pricing model(CAPM) principle, the paper let the credit rating result quantitative in the model. The paper simulate how many enterprises obtain loans and the bank’s expected return by change various parameters through NetLogo simulation platform. Finally, the paper put forward the corresponding policy recommendations according to the results of simulation.
