新质生产力与数字经济核心产业出口韧性:影响效应及作用机制OA北大核心CHSSCDCSSCICSTPCD

Based on the panel data of 30 provinces in China from 2008 to 2022,this paper empirically tests the intrinsic rela-tionship and impact mechanism between new-quality productivity and the export resilience of core industries in digital economy.The test results confirm that new-quality productivity can promote the resilience of core industries in digital economy,and that this conclusion still holds after a series of endogeneity and robustness tests.Heterogeneity test finds that compared with the west-ern,central and northeastern regions,new-quality productivity has a stronger effect on enhancing the export resilience of the core industries of digital economy in the eastern region,that compared with industrial digitization field,the role of new-quality produc-tivity in enhancing the resilience of industrial exports in the field of digital industrialization is more significant,that compared with the form of processing trade,new-quality productivity has a more significant impact on enhancing the export resilience of general trade forms in the core industries of digital economy.The mediation effect test finds that the complexity of export technology and the dependence on intermediate goods imports play a mediating role in the process of promoting the export resilience of core in-dustries in digital economy through new-quality productivity.
