英文摘要：
P2P lending activities have grown rapidly and have caused the huge and complex networks of debtor-creditor relationships. The aim of this study was to study the underlying structural characteristics of networks formed by debtor-creditor relationships. According attributes of P2P lending, this paper model the networks of debtor-creditor relationships as an evolving networks with addition and deletion of nodes. It was found that networks of debtor-creditor relationships are scale-free networks. Moreover, the exponent of power-law was calculated by an empirical study. In addition, this paper study what factors impact on the exponent of power-law besides the number of nodes. It was found that the both interest rate and term have significantly influence on the exponent of power-law. Interest rate is negatively correlated with the exponent of power-law and term is positively correlated with the exponent of power-law. Our results enriches the application of complex networks

中文摘要：
P2P借贷活动发展迅速，形成了庞大而复杂的借贷关系网络。本研究的目的是研究债务人-债权人关系形成的网络的潜在结构特征。根据P2P借贷的属性，本文将借贷关系网络建模为一个具有添加和删除节点的进化网络。研究发现，债务人-债权人关系网络是无标度网络。此外，通过实证研究计算了幂律指数。此外，本文还研究了除节点数外，还有哪些因素影响幂律指数。研究发现，利率和期限对幂律指数都有显著影响。利率与幂律指数呈负相关，期限与幂律指数呈正相关。我们的结果丰富了复杂网络的应用
