基于主营产品的中国矿业上市公司复杂结构关系研究

通过分析主营产品来研究我国矿业上市公司之间的复杂关系结构。研究以矿业上市公司为节点，把两个上市公司之间的主营产品的有重叠关系定义为两个节点有边，否则没有边，并据此按公司所主营产品的共有性构建公司之间关系的复杂网络模型，利用复杂网络理论及分析方法，通过计算网络中的节点度、网络度分布、聚集系数来分析主营产品关系下的网络结构特征。发现了我国矿业上市公司的整体结构关系特点，各个公司在整个行业中所处的地位及各公司之间的相互关联度，反映出其整体关系的复杂性，也揭示了节点与网络中其他节点之间的关系。研究能够帮助矿业公司做出正确的决策与调整，为上市公司在行业中提高竞争与合作起到推动作用，以利于企业快速、有效地向前发展。

COMPLEX STRUCTURAL CORRELATION OF CHINESE LISTED MINING  COMPANIES BASED ON THEIR MAIN PRODUCTS

This paper studies the complex structural correlation of Chinese listed mining companies based on their main products. A complex structural correlation mode is established from taking the listed mining companies as nodes, and their overlapped main products as conjunctional edge, and is used to analyze their network structural characters through node degree, network degree distribution and concentrating coefficient. The results reveal a complex overall structural correlation, and their industrial positions and mutual correlation, and reflect a relation between nodes. This paper aims at providing reference for mining companies to make decisions and adjustment, to improve their competitiveness, and to reach a fast and effective development.
