摘要：关系贷款被广义地解释为贷款人和借款人之间的强大合作关系。然而，虽然诸如贷款频率和数量等简单统计数据已在以往研究中被用作借贷关系强度的代理指标，我们仍然缺乏关于如何量化贷款关系强度的共识。我们提出统计测试，以确定关系贷款是银行之间的重要关系。将该方法应用于意大利银行间网络后发现，所有双边贸易中关系贷款的比例相当稳定，并且关系贷款人往往会在财务困境时要求更高的利率利率。

Identifying Relationship Lending in the Interbank Market: A Network Approach

Teruyoshi Kobayashi (Graduate School of Economics)，Taro Takaguchi（National Institute of Information and Communications Technology）

ABSTRACT

Relationship lending is broadly interpreted as a strong partnership between a lender and a borrower. Nevertheless, we still lack consensus regarding how to quantify the strength of a lending relationship, while simple statistics such as the frequency and volume of loans have been used as proxies in previous studies. Here, we propose statistical tests to identify relationship lending as a significant tie between banks. Application of the proposed method to the Italian interbank networks reveals that the fraction of relationship lending among all bilateral trades has been quite stable and that the relationship lenders tend to impose high interest rates at the time of financial distress.
