英文摘要：
  The weighted and directed network of countries based on the number of overseas banks is analyzed in terms of its fragility to the banking crisis of one country. We use two different models to describe transmission of shocks, one local and the other global. Depending on the original source of the crisis, the overall size of crisis impacts is found to differ country by country. For the two-step local spreading model, it is revealed that the scale of the first impact is determined by the out-strength, the total number of overseas branches of the country at the origin of the crisis, while the second impact becomes more serious if the in-strength at the origin is increased. For the global spreading model, some countries named \"triggers\" are found to play important roles in shock transmission, and the importance of the feed-forward-loop mechanism is pointed out. We also discuss practical policy implications of the present work.

中文摘要：
从一国银行危机的脆弱性出发，分析了基于海外银行数量的加权定向国家网络。我们使用两种不同的模型来描述冲击的传播，一种是局部的，另一种是全球的。根据危机的原始来源，危机影响的总体规模因国家而异。对于两步局部扩散模型，我们发现，第一次影响的规模取决于危机起源国的海外分支机构的总数量，即向外的力量，而如果危机起源国的力量增加，第二次影响会变得更严重。对于全球传播模型，发现一些被称为“触发器”的国家在冲击传播中起着重要作用，并指出了前馈回路机制的重要性。我们还讨论了当前工作的实际政策含义。
