In the context of the new era, the sustainable development of engineering supervision industry is an important and meaningful topic. This study defines the sustainable development of engineering supervision industry from the meaning of sustainable development, and puts forward the theoretical model of sustainable development of engineering supervision industry, and then puts forward the causal model of the sustainable development system of engineering supervision industry on the basis of literature research, and finally puts forward the strategy of sustainable development of engineering supervision industry, i.e., clarification of the positioning of engineering supervision, the reform of the content of the engineering supervision service, Finally, strategies for the sustainable development of engineering supervision industry are proposed, namely, clarifying the positioning of engineering supervision, reforming the content of engineering supervision services, giving full play to the role of engineering supervision industry associations, and increasing scientific and technological innovation and service innovation, etc. It is hoped that the development of China"s engineering supervision industry can provide certain guidance.
