英文摘要：
  Interbank markets are often characterised in terms of a core-periphery network structure, with a highly interconnected core of banks holding the market together, and a periphery of banks connected mostly to the core but not internally. This paradigm has recently been challenged for short time scales, where interbank markets seem better characterised by a bipartite structure with more core-periphery connections than inside the core. Using a novel core-periphery detection method on the eMID interbank market, we enrich this picture by showing that the network is actually characterised by multiple core-periphery pairs. Moreover, a transition from core-periphery to bipartite structures occurs by shortening the temporal scale of data aggregation. We further show how the global financial crisis transformed the market, in terms of composition, multiplicity and internal organisation of core-periphery pairs. By unveiling such a fine-grained organisation and transformation of the interbank market, our method can find important applications in the understanding of how distress can propagate over financial networks.

中文摘要：
银行间市场通常以核心-外围网络结构为特征，核心银行之间高度互联，将市场维系在一起，而外围银行主要与核心银行相连，但不在内部。这种模式最近受到了短期规模的挑战，银行间市场的特点似乎是一种具有更多核心-外围连接而非核心内部连接的二分结构。我们在eMID银行间市场上使用了一种新的核心-外围检测方法，通过显示网络实际上具有多个核心-外围对的特征，丰富了这幅图片。此外，通过缩短数据聚合的时间尺度，可以实现从核心-外围结构到两部分结构的过渡。我们进一步展示了全球金融危机如何在核心-外围对的构成、多样性和内部组织方面改变了市场。通过揭示银行间市场的这种细粒度组织和转变，我们的方法可以在理解危机如何通过金融网络传播方面找到重要的应用。
