中文摘要：
有效市场理论以线性化的假设来刻画资本市场，把市场看成是均衡系统或围绕均衡点变动的周期性系统。但实证检验对两种看法都不支持，市场是一个复杂系统，具有不可叠加性的特征。回顾资本市场复杂性理论的发展历程，从资本市场分形及混沌理论两方面归纳了资本市场复杂性的基本研究方法，综述了国内外资本市场复杂性的研究现状，在此基础上，总结出复杂网络、金融数据高维计算复杂性和人工股市模型等研究动向。
英文摘要：
Efficient Market Theory （EMT） describes the capital market using linearity hypothesis, which regards the market as an equilibrium system or a periodical system turning around the equilibrium point. But the empirical test results don＇t support both of them. Market is a complex and insuperposable system. Looking back on the complexity theories of capital market and the history of their developments, the principal approach to the study on the complexity of capital market is generalized at two aspects, i.e. , the fractal of capital market and the theory of chaos. Surveying the present situation of the study on the complexity of capital market at home and abroad, some focal points are found as the trend to the study, such as the complex network, complexity of higher-dimensional computation of financial data.
