香港恒生指数的波动性分析

利用粗粒化方法建立了香港股票市场的恒生指数和交易量之间关系的复杂网络模型,得到了该网络的一些重要拓扑特性,它们揭示了香港股票市场恒生指数和交易量联合波动的变化规律.通过计算网络的介数指标(BC)和反比参与率,找到网络的重要性节点,这些节点表示的波动模式在股票市场上控制和传递信息方面发挥重要的作用,对我们理解股票市场恒生指数和交易量的联合变化具有重要意义.最后将网络模型与随机网络进行比较,说明香港股票市场的恒生指数和交易量的联合变化具有统计稳定性.

Analysis of Fluctuation of Hong Kong Hang Seng Index

This paper refers to HSI and the transaction volume of Hong Kong stock market on the formation of complex network model. We obtain some important topology characteristics, it reveals the changes in law of Hong Kong stock market index and trading volume fluctuations. By calculating the betweenness centrality (BC) and IPR, we get some important topology nodes. The results showed that these significant patterns which denoted by the nodes play much more important roles in both information control and transport of stock market, and should be useful for us to more understand fluctuations regularity of stock index and trading volume. Moreover, by comparison to random networks, we could conclude that Hong Kong stock market is statistically stable.
