中国产业链供应链安全水平的测度、区域差异及动态演化OACHSSCD

Based on the intrinsic characteristics of industrial chain and supply chain security,this paper constructs a compre-hensive evaluation index system,then uses the entropy method,Dagum Gini coefficient method,and Kerenl density estimation method to measure the security level of industrial chain and supply chain in 286 prefecture-level and above cities of China from 2012 to 2022,and finally analyzes the changing trend,regional differences and evolution characteristics.The findings are shown as the following:The security level of China's industrial chain and supply chain is steadily increasing during the study period.There are significant regional differences in the security level of China's industrial chain and supply chain,with the largest differ-ence between the eastern and western regions and the largest difference within the eastern region.The overall differences in the se-curity level of China's industrial chain and supply chain mainly come from inter-regional differences.Except for the northeast re-gion,the absolute differences in the security levels of industrial chains and supply chains across the eastern,central and western regions have all shown a downward trend.Enhancing the stability of the industrial chain and supply chain,promoting the coordi-nated development of the industrial chain and supply chain in different regions,and deepening international cooperation in the in-dustrial chain and supply chain are important paths for promoting the safe and stable development of the industrial chain and sup-ply chain.
