摘要:

我们调查了金融市场数据,以确定哪些因素影响股票之间的信息流。在对韩国、日本、台湾、加拿大和美国市场数据的分析中,考虑了两个因素,即时间依赖性和效率程度。我们发现,随着时间间隔的增加,显著信息的频率降低。然而,在去除时间相关性的时间序列中没有观察到显著的信息流。这些结果表明,股票之间的信息流证据的时间依赖特性。此外,我们还发现,效率程度的差异在决定重要信息流的方向方面起着至关重要的作用。

英文摘要:

We investigated financial market data to determine which factors affect information flow between stocks. Two factors, the time dependency and the degree of efficiency, were considered in the analysis of Korean, the Japanese, the Taiwanese, the Canadian, and US market data. We found that the frequency of the significant information decreases as the time interval increases. However, no significant information flow was observed in the time series from which the temporal time correlation was removed. These results indicated that the information flow between stocks evidences time-dependency properties. Furthermore, we discovered that the difference in the degree of efficiency performs a crucial function in determining the direction of the significant information flow.
