Abstract:The realization of high quality of economic development needs to be led by high-level standards, and group standards, as an important institutional arrangement to promote economic development, play an increasingly obvious role in the construction of a new standard system. However, the lack of scientificity, standardization and coordination in the formulation of group standards has aroused the doubt and widespread concern from all walks of life. The establishment of group standard evaluation mechanism can improve the work efficiency and save social resources by correcting deviations in the work of group standards. Based on the analysis of the problems existing in the development of group standards in China, this paper constructs a preliminary evaluation mechanism of group standards by using PDSA cycle method, in order to provide Suggestions for the evaluation of group standards in China.
