摘　　要：为了探讨中国基金市场的网络结构,先通过二分网的单顶点网络构建了基金无向加权网络,再利用网络的基本几何统计量对网络结构特征进行分析.实证分析结果表明基金网络系统是小世界网络和同类匹配网络,并且网络度分布和点强度分布服从幂律分布.进一步分析,找到了这些网络特征的现实含义以及基金在股票投资中的一些特点.To study the network structure of Chinese fund market,the fund undirected and weighted network were constructed using bipartite network of fund market,and then the basic geometric statistics of network was used to analyze the structure of network.The statistical results showed that the network system are ＇small-world＇ network and assortative network,and the degree distribution and strength distribution are power-law.As further analysis,the practical significance of these network characteristics and some characteristics in the fund＇s equity investment were found.
