Abstract:The performance evaluation of creative research group project in National Natural Science Foundation of China funding system is divided into evaluation preparation stage, letter evaluation and meeting evaluation stage, and the stage of performance evaluation report writing, revision and release. Taking the performance evaluation of creative research group project in 2015 as an example, its workflow and specific implementation are analyzed. The creative research group project has the dual attributes of frontier exploration and talent training, as well as the characteristics of large funding, long cycle and loose assessment. The relevant performance evaluation work is designed based on the characteristics of the project, peer review and evaluation index system (including spot check project and overall project evaluation). Three research reports including the 2015 annual performance report of National Natural Science Foundation of China were obtained, and the evaluation work was successfully completed. The performance evaluation of creative research group project suggests that the evaluation of science and technology projects should pay attention to the characteristics and requirements of scientific research projects, constantly reform, standardize and optimize the project process management according to the national development strategy and requirements, pay attention to peer review, and constantly expand the paradigm and boundary of science and technology evaluation, so as to promote the scientific, reasonable, stable and orderly development of scientific research projects, and promote the level of science and technology evaluation in China.
