Influence network in Chinese stock market

Ya-Chun Gao, Yong Zeng, Shi-Min Cai

摘要:

在股票市场中,价格波动是相互影响的,即一家上市公司可以影响其他上市公司。本文以中国股票市场为例,通过构建一个有向网络,研究上市公司之间的影响关系。这种影响力网络具有明显的拓扑性质,特别是一些能够引导股市走势的大公司被识别出来。此外,通过对分布在不同经济部门的上市公司子网络的分析,发现不同经济部门之间的影响关系是完全不同的,其中存在三种连通性和枢纽型上市公司。此外,将影响力网络中心性指标所得到的上市公司排名结果与资产中心性指标所得到的上市公司排名结果进行了比较,为揭示和理解上市公司在股票市场中的重要性提供了启示。这些实证结果对于揭示中国股票市场和经济板块的拓扑特征以及上市公司之间的相互影响关系具有重要意义。

英文摘要:

In a stock market, the price fluctuations are interactive, that is, one listed company can influence others. In this paper, we seek to study the influence relationships among listed companies by constructing a directed network on the basis of Chinese stock market. This influence network shows distinct topological properties, particularly, a few large companies that can lead the tendency of stock market are recognized. Furthermore, by analyzing the subnetworks of listed companies distributed in several significant economic sectors, it is found that the influence relationships are totally different from one economic sector to another, of which three types of connectivity as well as hub-like listed companies are identified. In addition, the rankings of listed companies obtained from the centrality metrics of influence network are compared with that according to the assets, which gives inspiration to uncover and understand the importance of listed companies in the stock market. These empirical results are meaningful in providing these topological properties of Chinese stock market and economic sectors as well as revealing the interactively influence relationships among listed companies.
