Abstract:Nowadays, with the vigorous rise of a new round of scientific and technological revolution around the world, emerging disciplines continue to spring up, science and technology develop rapidly and show the characteristics of intersection and fusion. Meanwhile, complex models appear in the field of scientific research, and talents play an increasingly prominent role in the process of scientific and technological innovation. In this context, National Natural Science Foundation of China (NSFC) is facing a new development opportunity and challenge. It is increasingly significant for how to optimize funding policies, strengthen basic research, enhance talent support for basic research, and build an effective mechanism to condense the scientific problems of bottleneck technology. Focusing on the funding system and management mode of NSFC, we analyze the funding structure and strategies of various international funding agencies in this study. We summarize some meaningful experience and provide feasible suggestions for the optimization of the funding policy for the future development of NSFC. It is helpful for the high-quality development of basic research and the enhancement of China's innovation ability.
