| 中文摘要: |
| 识别银行间同业拆借市场中系统重要性并进行相应监督管理，对提高金融市场稳定性、应对流动性危机等意义非凡。运用复杂网络理论，采用最大熵法则及阀值法，根据2013-2015年三年间中国银行同业拆借市场相关交易数据构建我国银行同业拆借网络，进行网络拓扑结构分析并定位网络关键成员。研究发现我国同业拆借银行网络呈现小世界网络模型特征，银行在网络中核心程度与银行现实规模对应；研究中定位了市场中系统重要性银行，并从网络结构特征出发对金融监管提出若干建议。 |
| 英文摘要: |
| Crucial as it is, interbank market has a profound influence on the resilience of the whole financial market when facing crisis, and it is equally important to identify the key players in the Interbank market so as to better monitor and regulate the whole system. We built the network model of Chinese interbank lending market in 2013-2015 by adopting basic ideas from Complex Network and Maximum Entropy Model. Complex Network is an effective approach to dig into the characteristics of complicated structures with substantial nodes and links. After analyzing the nature of the network we found that Chinese interbank lending network bears the features of Small-world network model. Furthermore, the ranking of banks in the networks is compatible with the ranking of assets of banks in real life. Besides, we successfully locate the key players in the network, and make policy suggestions accordingly. |
