数字新质生产力对产业链韧性的影响研究OA北大核心CHSSCDCSSCICSTPCD

This paper selects the panel data of 30 provinces in China from 2013 to 2022 to empirically test the relationship between digital new quality productivity and industrial chain resilience by using a variety of econometric models.The results show that digital new quality productivity can significantly enhance the resilience of industrial chain.The results of the mediation effect test show that industrial structure upgrading plays a mediating role between digital new quality productivity and the resilience of industrial chain.The heterogeneity test results indicate that the promoting effect of digital new quality productivity on the resil-ience of industrial chains is stronger in eastern provinces,and the empowering effect of digital new quality productive force on the resilience of industrial chains is more significant.The threshold effect test results indicate that there is a single threshold effect of digital new quality productivity between digital new quality productivity and the resilience of industrial chain.
