The rationalization of industrial structure is of great significance to the rationalization of the entire economic structure and the formation of a virtuous circle of economic development, and is a necessary condition for promoting the development of social productive forces. The main reasons for the changes in industrial structure are resource conditions, science and technology and social needs. This article takes the improvement of science and technology to the effect of industrial structure as a clue to study what kind of industrial structure pattern should be established in our country. Now we introduce the research method of variable structure model, and establish the industrial structure change model in different stages of technology.
