基于元胞自动机的股票市场复杂性研究——投资者心理与市场行为
Study on Complexity in Stock Market Based Cellular Automata
【摘要】 在建立了基于元胞自动机的股票市场仿真模型的基础上,运用分形结构特征变量和稳定性变量来刻画股票市场的复杂性特征,考察了投资者从众行为这一投资心理与市场复杂性特征变量的相关关系.在股票市场稳定性特征中提出了离散度概念,用于度量市场的稳定性.研究表明,股票市场的复杂性特征变量与投资者心理存在着明显的相关关系.
【Abstract】 After the cellular automata based model of stock market having been formulated, variables reflecting fractal and stability are introduced to describe complexity in stock market, and relativity between investor’s imitation degree and market complexity are investigated. Discrete level is put forward to scale the market stability. The results show that there is a obvious correlation between investor’s imitation degree and market complexity.
