Abstract: According to the game theory, the financing model of SMEs in the multi-level supply chainfar from the core enterprise level is constructed. The financing characteristics of the two type enterprises (high operating capacity and low operating capacity) are compared. The paperstudies the existence of equilibrium solutions. The research shows that if the amount of enterprise loans and enterprise inventory orders is used to determine the type of enterprise,in the absence of blockchain technology, the equilibrium solution in the lending market does not necessarily exist; but if the blockchain technology exists, the equilibrium solution in the lending market always exists. The research results provide a new perspective for financial institutions reduce risks.

摘要： 根据博弈论的观点,构建了多层级供应链中距离核心企业层级较远的中小企业融资模型,比较了两种类型企业(高经营能力和低经营能力)的融资特点,分析了供应链上两种类型企业在是否存在区块链技术情形下融资达到均衡解的条件。研究表明,金融机构分别以企业贷款总量和企业库存订购量作为标准来判定企业类型的情形下,在区块链技术不存在时,借贷市场中的均衡解在一定条件下存在;但在区块链技术存在时,借贷市场中的均衡解总是存在。研究结果对于金融机构降低风险提供了一个新的视角。
