Against the backdrop of the deep integration of global industrial transformation and the dual carbon strategy, the synergistic transformation of digitalization and greenization has become the core driving force for cultivating new quality productive forces in manufacturing. Based on a theoretical perspective, this paper clarifies the intrinsic connection between digital-green synergy and new quality productive forces, explores the mechanisms by which synergistic transformation empowers new quality productive forces, examines the practical challenges in the current process of digital-green synergistic transformation in manufacturing, and proposes optimized transformation pathways grounded in industrial development realities. The aim is to promote manufacturing to break through transformation barriers, activate development momentum through deep digital-green integration, and contribute to the steady, high-quality development of the real economy.
