Evolutionary Game Study On The Interest Subjects’ Behaviors Of The Small And Medium Enterprise

Due to the drive of interests, a large number of discreditable behaviors appear in thecredit transactions. As a result, the phenomenon of credit loss generally exists in the smalland medium enterprises in China. To solve this problem, the premise is to establish andimprove the credit system of small and medium enterprises. However, enterprise creditsystem involves a lot of main credit subjects. The relationship between these credit subjects iscomplex. The changes of their interests and credit behaviors directly affect the effectivenessof the construction of small and medium enterprises credit system. Therefore, how to clarifythe complex interest’s relationship among the participating parties and inquiring into theevolution learning mechanism of their behaviors has an important effect on the establishmentof a balanced and dynamic small enterprises credit system. This is also the key point of thisstudy.Based on the study of small and medium enterprises’ credit status and the relatedreference, chapter2introduces four credit subjects, including small and medium enterpriseitself, financial institutions, guarantee agencies and government departments. Chapter3discusses three kinds of basic theory, including the credit theory, the evolutionary economicstheory and the evolutionary game theory.In chapter4,5and6, we established three evolutionary game models based on thesubjects’ interests, including model1：evolutionary game model between SMEs and financialinstitutions, model2：between guarantee agencies and banks, model3：between governmentsupervision department and SMEs. Then, we analyze the ESS and conduct the numericalsimulation experiment. Based on the model analysis and experimental results, we give some policyrecommendations on the construction and perfection of the small and medium enterprisescredit system. Standing at the micro level, we should improve the bank-enterprise creditrelationship and the credit guarantee system for SMEs. Standing at the macro level, weshould promote enterprise credit supervision system.
