With the advancement of sustainable development goals, digital technological innovation has emerged as a critical pathway for mitigating urban carbon emission intensity. Utilizing a balanced panel dataset of Chinese cities spanning 2012-2019, our paper examines the influence of digital technological innovation on urban carbon intensity. The findings reveal the following. (1) There exists an inverted U-shaped relationship between digital technological innovation and carbon intensity. (2) A nonlinear mediation mechanism is identified, whereby digital technological innovation influences carbon intensity through its effects on energy intensity and governmental environmental attention. (3) Substantive digital technological innovation reaches the turning point more rapidly. (4) The inverted U-shaped relationship holds exclusively for non-environmentally prioritized cities, while it is not evident in environmentally prioritized cities. (5) This relationship is consistently observed across both Broadband China pilot cities and non-pilot cities. These findings not only deepen the understanding of the interplay between digital technological innovation and carbon intensity, but also provide theoretical insights and practical guidance for achieving sustainable development objectives.
