基于上市公司年报供应链的核心企业识别方法研究OA

Based on the supplier and customer information disclosed in the annual reports of listed companies,a supply chain enterprise cooperation network is constructed,and the feature vector centrality,intermediary centrality,and proximity centrality indicators in social network analysis are used to quantify the strong influence,strong attraction,and strong integration of core supply chain enterprises.By collecting data from the information technology industry for empirical analysis,the core enterprises with significant influence on the entire supply chain in this field were identified,and the effectiveness of the method was verified.The research results indicate that this method can accurately identify core enterprises in the supply chain and reveal their network structure characteristics.This research expands the scenario of application for Competitive Technical Intelligence and provides new ideas and quantitative analysis methods for supply chain management and optimization,which is expected to improve the efficiency of supply chain management and help enterprises better optimize their supply chain structure.
