Abstract: Objective To analyze the equity of bed allocation in specialized public health institutions in the Chengdu-Chongqing-Luzhou region from 2017 to 2021,and predict the development in the next five years,in order to provide a scientific basis for promoting the coordinated development of regional public health care. Methods The Gini coefficient,Theil index and health resource agglomeration degree were used to analyze the equity of bed allocation in specialized public health institutions in the Chengdu-Chongqing-Luzhou region,and the grey GM（1,1） was used to predict the development in the next five years. Results The Gini coefficient by population and economic allocation was below 0.4 in Chengdu,above 0.4 in Chongqing,and above 0.5 in Luzhou. In terms of allocation by population,the Theil index ranged from 0.025 to 0.067 in Chengdu,from 0.159 to 0.235 in Chongqing,and from 0.279 to 0.361 in Luzhou. In terms of allocation by geography,the Theil index ranged from 0.154 to 0.173 in Chengdu,from 0.237 to 0.271 in Chongqing,and from 0.386 to 0.485 in Luzhou. In terms of allocation by economy,the Theil index ranged from 0.070 to 0.094 in Chengdu,from 0.167 to 0.316 in Chongqing,and from 0.226 to 0.447 in Luzhou. In terms of health resource agglomeration degree（HRAD）,the specialized public health institution beds were mainly concentrated in the first circle in Chengdu,in the metropolitan area in Chongqing,and in the three districts in Luzhou. The specialized public health institution beds in the first and second circle of Chengdu,the metropolitan area of Chongqing,and the four counties of Luzhou were all insufficient relative to the agglomeration population and economy. Conclusion Chengdu has better equity than Chongqing,and Chongqing has better equity than Luzhou. Inequity by geography and economy in Chengdu mainly comes from inter-region,and inequity in Luzhou mainly comes from intra-region. There are situations in Chengdu and Chongqing where equity by geography is at odds with equity by population and economy,and in Luzhou where equity by geography,population and economy are aligned.
