The World Stock Market Based on the Complex Networks

In order to research the stability and the inner community structure of the international stock network, this paper, based on complex network theory, by calculating the correlative relationship of the stock market index in different countries, and then, used the thrice MST and set up the network model of the stock markets in different countries. The influence-strength analysis was made use of to reach the conclusion that node, functioning as stability, does exist in the network. The Matlab programme was used to simulate and it is discovered that when was attacked, the stock market is robust at rand attack and fragile at intentional attack. The absolute betweenness centrality was advanced and the GN algorithmic routine was used to divide up the network and it is discovered that the community structure of the network is accord with the territorial-development of
