Abstract: Changes in the economic base,sooner or later, will lead to ideological changes. Before the reform and opening up, China's mainstream ideology has been around the "revolution" and "class struggle", the socialist construction is also under the guidance of the traditional revolutionary struggle. After the end of the cultural revolution, our party puts forward a series of new ideas and methods,such as the liberation and development of productive forces, Three Represents, scientific development,harmonious society and so on.While maintaining the stability, coherence and consistency are the mainstream ideology. The transition of mainstream ideology is realized. After the 18th national congress of the CPC, the concept of modern governance which focuses on top-level design and institutional mechanisms has gradually become the core concept of today's society. And the mainstream ideology of our country is being transformed into governance ideology.
