摘  要:文章基于区块链技术赋能供应链金融的视角,首次构建了嵌入二级供应链的银行挤兑理论模型,通过理论模型推演和数值算例,阐述了供应链金融以及区块链技术的应用影响银行挤兑风险的内生机制.结果表明,供应链金融以及区块链技术的应用通过改变银行贷款审查努力影响银行挤兑风险.区块链供应链金融对银行贷款审查努力的影响具有非对称性,这导致了其对于缓解银企之间信息不对称同样具有非对称性影响.而且区块链供应链金融在缓解中小企业信贷配给和维护金融稳定方面可能存在内在冲突,当区块链供应链金融缓解了银企之间的信息不对称,且高质量非核心企业的概率较高时,区块链技术的应用将提高非核心企业的信贷可得性,并导致银行挤兑风险上升.为此,监管部门可以通过适当收紧资本监管约束化解二者的冲突.From the perspective of supply chain finance empowered by blockchain technology,this paper proposes a new theoretical model of bank run embedding a two-echelon supply chain.Through theoretical derivation and numerical examples,we explain the endogenous mechanism of supply chain finance and the application of blockchain technology affecting bank run risk.Our model demonstrates that supply chain finance and blockchain technology affect bank run risk through banks'loan screening efforts.Blockchain-enabled supply chain finance has an asymmetrical effect on banks'loan screening efforts,which leads to a similar effect on alleviating information asymmetry between banks and enterprises.Furthermore,there may be an inherent conflict between the role of blockchain-enabled supply chain finance in mitigating credit rationing for SMEs and maintaining financial stability.When blockchain technology alleviates the information asymmetry between banks and enterprises,and the probability of high-quality non-core enterprises is at a high level,applying blockchain to supply chain finance will improve the credit availability of non-core enterprises and lead to a higher risk of bank runs.For this reason,the regulatory authorities can resolve this conflict by appropriately tightening capital regulatory constraints.
