中文摘要: 金融市场上异质信息的传播会导致金融市场的波动,甚至造成金融危机。研究异质信息风险的形成机理,是提出科学有效的风险预警措施的前提,在理论和实践上对金融市场风险管理具有重要意义。从复杂系统的视角,利用计算实验方法,结合复杂网络理论方法,在分析中国金融市场异质信息传播网络结构的基础上,构建投资主体之间、投资主体与媒体之间、媒体与媒体之间的信息传播双重网络模型,进而建立金融仿真实验平台,从下而上地挖掘异质信息风险因子及传播途径,从而提出有效的风险预警方法。首先分析金融市场异质信息特点和投资者行为模式;然后,应用计算实验金融方法构建具有中国特点的仿真实验金融平台。通过可控实验,研究异质信息风险形成机理;最后,建立信息风险指标体系,研究风险预警的策略和实施措施。本申请为理解金融市场波动本质与市场运行机制提供一个全新的视角,并为投资者做决策和监督部门监测信息披露做有效参考,促进金融市场稳定有序发展。

英文摘要: Heterogeneous information dissemination can lead to financial market fluctuations, even cause financial crisis. Researching the formation mechanism of heterogeneous information risk is the premise of putting forward scientific and effective risk early warning measures, and is of great significance on the financial market risk management in theory and practice. From the perspective of complex system, combined calculational finance method and complex network theory, based on the analysis of China's financial market heterogeneous information dissemination network structure, this research program constructe information dissemination dual-network model, among investors、investor and media、medium, establish a financial simulation platform, and mine of heterogeneous information risk factor and the dissemination way from the bottom up, thus putting forward effective risk warning method. First, analysing heterogeneous information characteristics and investors' behavior pattern is primary; Then, using the method of agent-based computational finance, it is of great inportance to establish a financial simulation platform, which has Chinese characteristics. Throuth controlled experiments, heterogeneous information risk formation mechanism can be found out; Finally, we set up information risk indicator system and research the
