摘　　要：近些年来,世界金融系统面对着严峻的挑战,在一波未平一波又起的浪潮下,各国政府对本国金融系统的监管强度都有了明显提升。而将企业与银行视为节点,借贷关系视为连边,则该网络系统可视为一种加权网络模型,本文通过引入幂律分布复杂网络,以现实金融体系下各企业的生存状况为基础,设计了一种网络模型,并对节点出入度之比进行约束,对不同约束条件下网络的稳定性进行了研究。In recent years,with the normalization of the new coronavirus epidemic and the intensification of the Russian-Ukrainian war,the world financial system is facing severe challenges.Under the wave of unrest and wave after wave,the supervision intensity of governments on their own financial systems has been significantly improved.The network system can be regarded as a weighted network model when the enterprise and the bank are regarded as nodes and the loan relationship is regarded as a link.In this paper,a network model is designed by introducing a power-law distribution complex network and based on the living conditions of each enterprise under the real financial system.The stability of the network under different constraints is studied by restricting the ratio of node access degree.
