英文摘要:
With the network methods and random matrix theory, we investigate the interaction structure of communities in financial markets. In particular, based on the random matrix decomposition, we clarify that the local interactions between the business sectors (subsectors) are mainly contained in the sector mode. In the sector mode, the average correlation inside the sectors is positive, while that between the sectors is negative. Further, we explore the time evolution of the interaction structure of the business sectors, and observe that the local interaction structure changes dramatically during a financial bubble or crisis.

中文摘要:
利用网络方法和随机矩阵理论,我们研究了金融市场中社区的互动结构。特别是,基于随机矩阵分解,我们阐明了业务部门(子部门)之间的局部交互主要包含在部门模式中。在部门模式中,部门内部的平均相关性为正,而部门之间的平均相关性为负。此外,我们还探讨了商业部门互动结构的时间演变,并观察到在金融泡沫或危机期间,当地的互动结构发生了巨大变化。
