Abstract Based on panel data from 31 provinces and cities in China from 2009 to 2021, this paper use spatial error model to empirically analyze the impact of digital new infrastructure and green technology progress on the transformation of low-carbon economy. The research results indicate that both digital new infrastructure and green technological progress play a significant role in facilitating the transition to a low-carbon economy. Moreover, there is a significant spatial correlation between the two factors and the transition to a low-carbon economy. And this conclusion holds true even after a series of robustness tests. At the same time, the improvement of digital new infrastructure level can enhance the empowerment effect of green technology progress on low-carbon economic transformation. The results of sub-sample study show that there is obvious regional heterogeneity in the promoting effect of digital new infrastructure and green technology progress on the transformation of low-carbon economy, which is significant in the eastern region and not significant in the central and western regions. The threshold effect test shows that green technological progress plays a threshold effect between digital new infrastructure and the transformation to a low-carbon economy. After crossing the threshold, the assistance of digital new infrastructure in the low-carbon economy transformation has significantly increased in the eastern, central, and western regions, with a more significant effect observed in the western region. The three sub-dimensions of digital new infrastructure are conducive to the transformation of low-carbon economy, among which the positive enabling effect of integrated infrastructure construction is the strongest.
