Digital technology adoption significantly improves carbon-emission efficiency in Chinese metropolitan areas, according to a study published in Air Quality, Atmosphere & Health that analyzed panel data spanning 2010 to 2023. The research, led by Wanhong Li and colleagues, examined how the uptake of digital technologies interacts with regional governance structures in some of the world’s most emission-concentrated urban clusters.
Using a Tobit model and panel threshold regression, the researchers found that digital technology adoption enhances carbon-emission efficiency in a stage-dependent core-periphery pattern. Core cities captured the strongest effects first, but the spread of benefits toward peripheral areas depended on two conditions: collaborative governance among jurisdictions and adequate transportation infrastructure. Without these supporting factors, the efficiency gains remained concentrated in urban centers rather than diffusing outward.
The study also documented what the authors call a coordination compensation effect. Digital technology adoption exerted a stronger positive influence on carbon-emission efficiency in regions with weaker initial market and policy coordination, suggesting that digitalization can partially substitute for underdeveloped institutional frameworks.
Transportation infrastructure showed a nonlinear moderating effect on the relationship. Its positive influence was strongest at a medium level of development, while both insufficient and excessive transportation infrastructure weakened the effect of digital technology adoption on carbon-emission efficiency. The authors suggest this points to an optimal range of infrastructure development for maximizing the environmental returns of digitalization.
Theoretically, the study identifies key drivers and mechanisms of coordinated regional carbon governance within collaborative governance frameworks. Practically, the authors argue the findings offer actionable insights for promoting sustainable development strategies in the digital era, particularly for metropolitan areas seeking to balance economic digitalization with emission-reduction goals.
