As the major production sector of China, manufacturing has a serious problem of pollution and energy consumption. Under the accelerated promotion of “Green Manufacturing”, exploring how to realize the transformation and upgrading of manufacturing in the face of increasingly stringent environmental regulations is of great significance. Taking the new Environmental Protection Law as an example, difference in difference method was used to demonstrate high-intensity environmental regulation’s positive feedback on the sustainable development of manufacturing enterprises from the perspective of ESG （environmental，social，governance）performance.
