“…In some cities, NSCs do not significantly exacerbate local CO 2 emissions. Existing research has explored various dimensions, including enterprises [4], cities [3,10,11,13], regions [6,9,19], etc., providing positive impacts of digitization on environmental sustainability from multiple perspectives including digital economy [3,6,9,19,27], specific digital technologies (e.g., the internet, big data, artificial intelligence) [12,15,14,28], and digital infrastructure [10,11,13,[20][21][22][23][24]. Consistent with the research results of Rao et al, Tang and Yang, and Wu et al [11,13,20], we find that China's National Supercomputing Centers have significant carbon emission effects.…”
