Digital transformation of enterprises toward greener development is a critical lever for advancing a low‐carbon economic paradigm under the dual‐carbon mandate. Against the backdrop of sustained growth in emerging digital‐trade models, identifying digital opportunities to facilitate corporate green transformation has become a central concern. This study employs panel data from Chinese publicly listed firms spanning 2001–2022 to empirically examine the impact of digital trade on corporate green transformation and to elucidate the underlying mechanisms. Our fi ndings indicate that the expansion of digital trade signifi cantly accelerates fi rms’ green‐transformation processes, and this eff ect is amplifi ed in the presence of stringent environmental‐ regulatory policies. Mechanism analysis reveals two principal channels through which digital trade promotes green transformation: namely, cost reduction and diminished market power. In particular, the attenuation of firms’ monopoly power reflects a virtuous outcome stemming from digital technologies’ enabling of more effi cient operations. Heterogeneity tests further demonstrate that the positive impact of digital trade on green transformation is especially pronounced for manufacturing fi rms characterized by high R&D intensity, as well as those in labor‐and capital‐intensive sectors. An investigation into market integration underscores that, relative to segmented markets, higher degrees of market integration more eff ectively foster corporate green transformation; however, excessive industry agglomeration may impede this process. This analysis off ers a digital‐trade-oriented pathway for promoting corporate green transformation and provides policy implications, such as the accelerated development of digital technologies to support the attainment of dual‐carbon objectives.
