中文摘要: 金融危机作为典型的金融极端事件,尽管发生频率较低,但一旦发生往往带来灾难性后果,且经济全球化进程的加深会导致金融危机在不同市场间大规模的传导和扩散,因此,对那些蕴含巨大风险损失甚至灾难性后果的极端事件进行定量研究具有相当重要的现实意义。为了弥补传统风险管理理论方法(不考虑金融极端事件"时间效应")的不足,本项目拟从时间维及空间维双重视角,运用多重分形理论及极值理论深入研究股市极端事件的典型特征机理,探索股市危机的预警方法。主要内容包括:①在空间维上,研究股市极端事件价格行为特征、交易量行为特征及价-量联合行为特征;②在时间维上,研究股市极端事件重现时间间隔特征及发生频率特征;③ 研究金融极端事件跨市场间的扩散和传导机制,对金融危机的传染时点,传染方向及传染强度等特征进行深入探索;④在此基础上,建立基于时间维及空间维双重特征属性的极端事件综合预警模型,以期对金融风险管理提供新思路和新方法。

英文摘要: As typically financial extreme events, financial crisis will lead to disastrous consequences although the frequency of financial crisis is relatively low. And the economic globalization will lead to financial contagion among different countries and different markets. Therefore, it is important to study the financial extreme events. In order to make up the limitation of traditional risk management theory and tools which ignores the "time effects" of financial extreme events, the project intends to apply multifractal theory and extreme value theory to study the stylized facts of financial extreme events and explore the early warning methods of the stock market crisis. The main contents include: Firstly, from the aspect of space dimension, it intends to study the price fluctuation behavior, the volume fluctuation behavior and the price-volume behavior. Secondly, from the aspect of time dimension, it intends to study the inter-event time series and the frequency of extreme events. Thirdly, it intends to study the financial contagion mechanism among international stock markets.And it intends to study the contagion time, contagion direction and contagion intensity. Finally, on the basis of these above-mentioned results, the useful information based on time dimension and space dimension are combined to establish a pred
