中国数字产业链韧性测度、时空演化与区域差异研究OA北大核心CHSSCDCSSCICSTPCD

This paper is based on the four dimensions of basic ability,the resistance ability,recovery ability,and sustainabil-ity ability of digital industry chain to establish an evaluation index system for the resilience of China's digital industry chain.On this basis,the entropy method is used to calculate the resilience level of the digital industry chain from 2015 to 2021,and the Theil index and local Moran's index are adopted to explore the spatiotemporal evolution characteristics and regional disparities of the resilience level of China's digital industry chain.The results go as below:The overall resilience level of the national digital in-dustry chain shows a steady upward trend,and the three regions show a distribution pattern of the eastern region>the western re-gion>the central region.The overall gap in the resilience level of the digital industry chain across the country and different re-gions continues to narrow over time,and mainly comes from intra-regional gap.The resilience level of the digital industry chain has a significant spatial correlation,and the"high-high"agglomeration and"low-low"agglomeration are the main ones.
