数实技术融合、新质生产力与战略性新兴产业突破性创新OACHSSCD

As the key focus of the integration of digitalization and real economy in the field of technology,digitalization and real economy(digital-real)technology integration can break the traditional innovation path dependence on the real industry,pro-mote disruptive technological breakthroughs and industrial paradigm changes,and has important practical significance for promot-ing breakthrough innovation of strategic emerging industries.This paper selects the panel data of 1517 listed companies in strate-gic emerging industries in China from 2013 to 2024,and uses multiple econometric models to empirically test the effect and mech-anism of digital-real technology integration on breakthrough innovation of strategic emerging industries.The results are shown as the following:First,digital-real technology integration can have a positive effect on breakthrough innovation of strategic emerging industries,and this conclusion remains valid after robustness and endogeneity tests.Second,the results of the mediating effect test show that digital-real economy technology integration can promote breakthrough innovation of strategic emerging industries through the path of promoting the development of new quality productivity,that is,new quality productivity plays a partial mediat-ing effect in the process of digital-real technology integration empowering breakthrough innovation of strategic emerging indus-tries.Third,the results of heterogeneity test show that the empowering effect of digital-real technology integration on breakthrough innovation of strategic emerging industries has significant differences under different enterprise sizes,ownership properties,indus-try attributes and innovation environments.
