Abstract:Large Research infrastructure is an important technical support for the development strategy of the country's scientific and technological power。Development research of large research infrastructure has been a weak link in the construction of infrastructures, which seriously restricts the development of infrastructures in China. Through the two examples of China's infrastructures construction project ——the LAMOST telescope and the FAST telescope, this paper analyzes the importance of the development research for the successful construction of the project. And through the management and investment of NSF and ESFRI on the development research of infrastructures, the main points of the management of development on foreign infrastructures are analyzed. On this basis, this paper emphasizes that development research is play a very important role in the construction and development of infrastructures, and propose a development research management system and mechanism for the sustainable development of infrastructures.
