Abstract: Objective To explore the advantages and feasibility of the co-teaching mode of general hospital and specialized hospital in standardized training of pediatric residents. Methods From 2016 to 2018，the residents received theco-teachingmode of Peking Union Medical College Hospital andCapital Institute of Pediatrics.And they were questioned by Systematic Evaluation of Teaching Qualities.The residents，who have completed the standardized training in Peking Union Medical College Hospital from 2013 to 2016，were questioned by Systematic Evaluation of Teaching Qualities too. Compare the results of the two groups of questionnaires. UseSPSS to analyze the differences in the quality of training，teaching attitudes and abilities，and teaching effect between the two groups. Results There were significant differences between the observation group and the control group in terms of training content，humanistic education and heuristic teaching (P＜0.05).The co-teachingmodeis superior to single-teaching mode in the content of standardized training of resident doctors. But humanistic education and heuristic teaching have more advantages. Conclusion The co-teaching mode is feasible for the standardized training of Pediatrics in general hospitals，which can solve the problems of insufficient disease types and imperfect establishment of sub-specialties. But in order to carry out the co-teaching smoothly and effectively，we need a unified teaching mode，perfect supervision and feedback mode.
