This paper analyzed the change characteristics and trend of income structure of public Traditional Chinese Medicine （TCM） hospitals in a province， so as to provide reference and basis for deepening the reform of medical service prices. Based on the medical income data of all public TCM hospitals in the province from 2015 to 2019， the income structure of outpatient， emergency and inpatient was analyzed by the structural change analysis and the grey correlation method. The structural change analysis showed that Chinese patent medicine， diagnosis and examination were the main sources of outpatient income change， while western medicine， health materials and laboratory were the main sources of inpatient income change. The grey correlation method showed that the income from western medicine， Chinese herbal medicine and laboratory tests had strong correlation with outpatient and emergency income， and the income from operations， beds and treatment had strong correlation with inpatient income. The study found that the proportion of western medicine income in TCM hospitals was high， and the proportion of Chinese herbal medicine income increased year by year. The increase of medical service income was slow， and the adjustment of medical service prices in TCM hospital lagged behind. The income from health materials had caused more changes in the structure of inpatient income. It is suggested that TCM hospitals should strengthen their own economic management and give full play to the characteristic advantages of TCM. The policy of centralized procurement of drugs and consumables should be promoted continuously. The dynamic adjustment mechanism of TCM medical service prices should be improved.
