In order to study the universality of the interactions among different markets, we analyze the cross-correlation matrix of the price of the Chinese and American bank stocks. We then find that the stock prices of the emerging market are more correlated than that of the developed market. Considering that the values of the components for the eigenvector may be positive or negative, we analyze the differences between two markets in combination with the endogenous and exogenous events which influence the financial markets. We find that the sparse pattern of components of eigenvectors out of the threshold value has no change in American bank stocks before and after the subprime crisis. However, it changes from sparse to dense for Chinese bank stocks. By using the threshold value to exclude the external factors, we simulate the interactions in financial markets.
革新，包含工艺的转变和管理重组，在现代社会引起重要变化。在这份报纸，调查革新怎么能被支持，我们建议一个基于比赛的模型学习人的创新行为的 co 进化的动力学。没有规模的网络上的模拟被进行，在哪个每个节点的创新行为基于关于它的革新的反馈坚定、更新，也就是革新地位的散开。模型的数字模拟产生一系列模式，它关于真实世界的创新行为与民族日报经验和感觉一致。明确地，动力学上的各种各样的可伸缩的空间与时间的性质和富有的结构的影响能被观察。这个模型提供一条新奇途径理解创新行为的进化并且为革新提升的策略研究提供卓见。
