Abstract
Achieving synergies in reducing pollution and carbon emissions has emerged as a crucial strategic goal in the new development phase. To investigates whether digital economy(DE), as a novel dynamic energy in this stage, can effectively contribute to the reduction of pollutants and carbon emissions. Accordingly, this study focuses on 265 cities in China spanning from 2011 to 2019. The study introduces the concept of the efficiency of synergistic management of pollutants and carbon emissions (SEPC). It utilizes an econometric model to empirically examine the pollution and carbon reduction effects of digital ecomomy, along with its implementation path. The findings reveal the following: (1) The impact of DE on SEPC exhibits a noticeable non-linear pattern, resembling a “U” shape. Moreover, significant spatial spillovers resulting from this nonlinearity are observed. (2) The mechanism analysis indicates that DE influences SEPC by affecting the energy framework, promoting green technology innovation, shaping industrial composition, and influencing public concern for the environment. (3) Heterogeneity analysis suggests that the influence of DE on SEPC is more pronounced in innovative cities, smart cities, and cities with higher levels of government intervention. This study validates the pivotal role of DE in advancing synergies for pollution and carbon reduction. Furthermore, it serves as a valuable reference for achieving dual carbon objectives.
