数字新质生产力对经济双循环发展的影响研究OACHSSCD

Digital new quality productivity,as an advanced productivity quality state formed by the combination of data,com-puting power and algorithms,can promote the rapid flow and efficient matching of factor resources,unlock all links such as pro-duction,distribution,circulation and consumption,and it is an important driving force for promoting the development of economic dual circulation.Based on the panel data of 30 provinces in China from 2013 to 2024,this paper empirically explores the impact effect and mechanism of digital new quality productivity on the development of economic dual circulation.The results show that digital new quality productivity can positively empower the development of economic dual circulation,and this conclusion still holds after a series of robustness and endogeneity tests.The results of the heterogeneity test show that the impact of digital new quality productivity on the development of economic dual circulation presents regional heterogeneity characteristics of"eastern re-gion>central region>northeastern region>western region"and"high marketization level>low marketization level".The results of the mechanism test confirm that disruptive technological innovation is the transmission mechanism through which digital new quality productivity affects the development of economic dual circulation.The results of the spatial spillover effect test show that the impact of digital new quality productivity on the development of economic dual circulation has a positive spatial spillover effect.
