In order to study the performance of public health supply and its influencing factors in Anhui, 15 relevant indicators were selected from the three dimensions of pressure, state and response of public health supply, and the performance evaluation index system of public health supply was constructed for Anhui.The performance of public health supply and its influencing factors were evaluated comprehensively by using the latest data and the entropy-Tobit model in Anhui.It is believed that the performance of public health care supply shows a dynamic fluctuation trend of "fast-stable-faststable" in Anhui, and that the pressure of public health care supply is still high and the supply situation is not optimistic, but the supply response index has increased significantly.The regression of Tobit model shows that the proportion of public health care expenditure presents the effect of diminishing returns to scale, population density and the performance of public health supply are negatively correlated, while the per capita GDP, urbanization level and fiscal self-sufficiency rate are positively correlated with the performance of public health supply, but the impact of fiscal self-sufficiency rate is not significant.Based on this, some countermeasures and suggestions are put forward to promote the performance of provincial public health supply.
