英文摘要:
We investigate hierarchical structures of the European countries by using debt as a percentage of Gross Domestic Product (GDP) of the countries as they change over a certain period of time. We obtain the topological properties among the countries based on debt as a percentage of GDP of European countries over the period 2000-2011 by using the concept of hierarchical structure methods (minimal spanning tree, (MST) and hierarchical tree, (HT)). This period is also divided into two sub-periods related to 2004 enlargement of the European Union, namely 2000-2004 and 2005-2011, in order to test various time-window and observe the temporal evolution. The bootstrap techniques is applied to see a value of statistical reliability of the links of the MSTs and HTs. The clustering linkage procedure is also used to observe the cluster structure more clearly. From the structural topologies of these trees, we identify different clusters of countries according to their level of debts and economic ties. Our results show that by the debt crisis, the less and most affected Eurozones economies are formed as a cluster with each other in the MSTs and hierarchical trees.

中文摘要:
我们通过使用债务占欧洲国家国内生产总值(GDP)的百分比来调查欧洲国家的等级结构,因为债务在一定时期内会发生变化。通过使用层次结构方法(最小生成树(MST)和层次树(HT))的概念,我们获得了2000-2011年间基于债务占欧洲国家GDP百分比的国家间拓扑性质。这一时期也被划分为与2004年欧盟扩大有关的两个分时期,即2000-2004年和2005-2011年,以测试各种时间窗口并观察时间演变。引导技术用于查看MST和HTs链路的统计可靠性值。聚类链接过程也被用来更清晰地观察聚类结构。根据这些树的结构拓扑,我们根据债务水平和经济联系确定了不同的国家集群。我们的研究结果表明,受债务危机影响较小且影响最大的欧元区经济体在MST和等级树中形成了一个集群。
