摘要: 利用复杂网络的理论和方法分析参与我国矿业上市公司股权融资的金融机构之间的关系及金融机构与上市矿业公司融资的关系,通过获取的73家金融机构与我国125家上市矿业公司关系情况的相关数据,运用UCINET和Excel作为统计分析工具,对金融机构之间的凝聚子群从派系和K—核角度进行详细分析。结果表明我国上市矿业公司股权融资具有显著的趋同关系结构,并发现了金融机构子群分布情况、投资趋同状况和金融机构活跃程度。从数据分析中还发现了网络中的金融机构之间的关联非常紧密,派系数目较多,共有121个派系之多,而且在各派系之间存在着较高的重叠性。虽然派系较多,但是核心比较明显,绝大多数子群都是围绕国有四大银行等大型金融机构而形成。
