英文摘要:
We investigate the spatial and temporal structures of four financial markets in Greater China. In particular, we uncover different characteristics of the four markets by analyzing the sector and subsector structures which are detected through the random matrix theory. Meanwhile, we observe that the Taiwan and Hongkong stock markets show a negative return-volatility correlation, i.e., the so-called leverage effect. The Shanghai and Shenzhen stock markets are more complicated. Before the year 2000, the two markets exhibit a strong positive return-volatility correlation, which is called the anti-leverage effect. After 2000, however, it gradually changes to the leverage effect. We also find that the recurrence interval distributions of both the trading volume volatilities and price volatilities follow a power law behavior, while the exponents vary among different markets.

中文摘要:
我们研究了大中华区四个金融市场的时空结构。特别是,我们通过分析通过随机矩阵理论检测到的部门和子部门结构,揭示了这四个市场的不同特征。同时,我们观察到台湾和香港股市表现出负的收益-波动相关性,即所谓的杠杆效应。上海和深圳股市更为复杂。在2000年之前,这两个市场表现出强烈的正收益-波动相关性,这被称为反杠杆效应。然而,在2000年之后,它逐渐转变为杠杆效应。我们还发现,交易量波动率和价格波动率的递推区间分布都遵循幂律规律,而指数在不同的市场中有所不同。
