摘要:

针对供应链金融中存在的风险,以应收账款保理业务为研究对象,对影响供应链金融参与主体决策的因素进行分析,构建中小企业、金融机构双方的演化博弈模型,通过对比区块链技术引入前后演化稳定策略的变化,分析区块链技术解决供应链金融风险的作用机制,并以实际案例为背景展开算例分析。研究发现,首先,信用风险对金融机构是否接受融资业务决策起决定性作用,区块链技术可以降低金融机构的操作风险,从而提高了金融机构的业务收益;其次,区块链技术所形成的严格监管环境使中小企业与核心企业的违约行为时刻处于高风险状态,无论中小企业合谋所能获得的利润分配比例为多少都不会选择违约,从而有效解开了中小企业守约概率增加却无法得到金融机构贷款的悖论,进而使金融机构与中小企业间的演化博弈均衡于金融机构接受业务申请,中小企业守约,且收敛效果更好。因此,区块链技术不仅降低了金融机构的融资风险,也有助于解决中小企业融资难题。

Abstract:

Because of the risks existing in supply chain finance, taking accounts receivable factoring business as the research object, the factors affecting the decision-making of the participants in supply chain finance are analyzed, an evolutionary game model between small and medium-sized enterprises and financial institutions is constructed, and the mechanism of blockchain to solve the financial risks of the supply chain is analyzed by comparing the changes of evolutionary stability strategies before and after the introduction of blockchain technology. And taking the actual case as the background for example analysis, the main conclusions are verified. It is found that firstly, credit risk plays a decisive role in whether financial institutions accept financing business decisions. Blockchain technology can reduce the operational risk of financial institutions and improve the business income of financial institutions; Secondly, the strict regulatory environment formed by blockchain technology makes the default behavior of small and medium-sized enterprises and core enterprises in a high-risk state at all times. No matter the profit distribution proportion that small and medium-sized enterprises can obtain through collusion, they will not choose to default, which effectively solves the paradox that small and medium-sized enterprises cannot obtain loans from financial institutions despite the increased probability of compliance. Then, the evolutionary game between financial institutions and small and medium-sized enterprises is balanced in that financial institutions accept business applications, small and medium-sized enterprises abide by the contract, and the convergence effect is better. Therefore, blockchain technology not only reduces the financing risk of financial institutions, but also helps to solve the financing problems of small and medium-sized enterprises.

Key words: blockchain, supply chain finance, account receivable factoring, evolutionary game
