Objective: To analyze the allocation of health resources and the service output efficiency of medical institutions in 13 regions of Jiangsu Province from 2011 to 2020，so as to provide references for improving the allocation efficiency of health resources. Methods: DEA-BCC and DEA-Malmquist models were used to analyze the static and dynamic efficiency of input and output of health resources. Results: In 2020，the average value of total factor productivity index of Jiangsu Province was 0.993，indicating that the output efficiency of medical services decreased on the whole，with an average reduction of 0.3 %. Among them，the change range of technological progress index was small，and the ability of service innovation was stagnant. From 2011 to 2020，among the total factor productivity index in the 13 regions5 regions were greater than 1 and 7 regions were less than 1，indicating that the efficiency of service output declined in most regions. Conclusions: There were regional differences in the allocation of medical and health resources，poor comprehensive efficiency and stagnant innovation ability in Jiangsu. It was necessary to accelerate technological innovation and regional coordination in weak areas，make reasonable planning and regulation，and improve the utilization efficiency of health resources.
