[Purpose/significance]At present, the research on the ways, methods and effects of librarian training in the maker space is not enough. The paper intends to apply the principle of the accumulative radiation effect to the librarian training in maker space. Based on the grounded theory and method , it encodes and analyzes the interview data, proves the existence of the accumulative radiation effect in librarian training and identifies its influencing factors in order to help managers overcome the bottlenecks and obstacles of librarian training, find new breakthroughs in training channels, and finds new ideas in training content and methods.[Method/process]In the domestic public libraries, university libraries and social institutions, 52 experienced and outstanding Librarians were selected to obtain interview data. On this basis, the concepts and categories of open coding, spindle coding and selective coding based on grounded theory were extracted, and the coding analysis was carried out according to the standard process.[Result/conclusion]On the basis of coding, the model of influencing factors (AIPE) of librarians' training in maker space is constructed, so as to clarify the occurrence and development of the radiation effect of librarians' training, to push the resource optimization of space training, the collection, sharing, show the effect and influence of librarians' training.
