区块链技术对中小企业信用融资策略的影响机制研究

The Impact Mechanism of Blockchain Technology on Credit Financing Strategies for Small and Medium-sized Enterprises

以中小企业与金融机构作为金融系统的参与主体,将区块链技术引入在线信用评估服务,构建金融机构向中小企业信用融资的演化博弈模型,对比区块链技术引入前后系统均衡的变化,分析其作用机制,并进行数值仿真分析。研究发现:中小企业贷款过程中的风险主要包括伪造骗贷风险和业务风险,前者是决定金融机构是否同意贷款的关键因素;引入区块链可以减少融资管理和融资业务中的失误,降低中小企业经营性失信的概率;在线信用评估服务引入区块链后,违约成本成为中小企业进行策略选择的决定性因素,中小企业的违约成本大幅提高,从而有效降低金融机构的融资风险。

Small and medium-sized enterprises and financial institutions are taken as participants in the financial system,this study introduces blockchain technology into online credit assessment services.It constructs an evolutionary game model for providing credit financing from financial institutions to SMEs,comparing the changes in system equilibrium before and after the introduction of blockchain technology,and analyze its mechanisms,followed by numerical simulation analysis.According to our studies,risks in the SME loan process primarily include counterfeit fraud risks and operational risks,with the former being a crucial determinant for financial institutions in deciding loan approvals.The introduction of blockchain can reduce errors in financing management and operations,thereby lowering the probability of SME operational misconduct.After the introduction of blockchain into online credit assessment services,default costs become a decisive factor for SMEs in making strategic choices.It significantly increase default costs for SMEs,effectively reduce financing risks for financial institutions.
