Since the country began to implement the reform and opening-up policy more than 40 years ago

concept of country development goes through three changes with the change of different age topics. In initial implementing the reform and opening-up policy period

the country restarted development concept aiming to reconstruct development foundation. This is response to how to realize development. In new time

the country changed from restarting development to developmentalism. The main concern is how to develop more quickly. When it comes to new age

developmentalism transforms into new development concept. The country begins put more attention on development quality. How to develop better becomes modern age topic. From the evolution of development concept

we can tell that modernization has always been core element of development concept

government intervention and system construct realistic power to evolution of development concept and contradictive movement of the productive forces and production relations constructs basic logic of evolution of development concept. Country development concept has development continuity

multiple development characteristic and practicability to use different development forms to service general development of the country. In modern specific space-time structure

we should show up openness and inclusiveness to different development forms

implement flexible public policy to release value space of different development forms and analyze mutual-construction mechanism of different development forms guided by practice to promote discourse innovation of Chinese development research.
