英文摘要：
We investigate hierarchical structure in various complex systems according to Minimum Spanning Tree methods. Firstly, we investigate stock markets where the graphis obtained from the matrix of correlations coefficient computed between all pairs of assets by considering the synchronous time evolution of the difference of the logarithm of daily stock price. The hierarchical tree provides information useful to investigate the number and nature of economic factors that have associated a meaningful economic taxonomy. We continue to use this method in social systems (sport, political parties and pharmacy) to investigate collective effects and detect how single element of the system influences on the other ones. The level of correlations and Minimum Spanning Trees in various complex systems is also discussed.

中文摘要：
我们根据最小生成树方法研究各种复杂系统的层次结构。首先，我们研究了股票市场，其中通过考虑每日股价对数差的同步时间演化，从所有资产对之间计算的相关系数矩阵中获得图形。层次树提供了有用的信息，用于调查与有意义的经济分类法相关的经济因素的数量和性质。我们继续在社会系统（体育、政党和制药）中使用这种方法来调查集体效应，并检测系统中的单一因素如何影响其他因素。文中还讨论了各种复杂系统中的关联度和最小生成树。
