In the face of the rigid constraints of the domestic “carbon neutrality” strategy and the continuous escalation of global green trade barriers, this paper aims to integrate existing research results and construct a systematic response framework for the green transformation of the discrete manufacturing industry, driven by three engines: “governance foundation building, technological innovation, and market empowerment”. The research shows that discrete manufacturing enterprises must abandon the fragmented technological renovation mindset and instead adopt a systematic strategic approach driven by the three engines.
