Objective:To evaluate and analyze the efficiency and influencing factors of government health expenditure in the Yangtze River Delta region,so as to provide a reference for promoting the process of health integration in the Yangtze River Delta region.Methods:The study employed the entropy method to measure the efficiency of government health expenditure in each city and analyzed its spatial heterogeneity and spatial evolution characteristics.Spatial correlation analysis and spatial econometric model were used to test its spatial correlation and analyze its influencing factors.Results:The average efficiency of government health ex-penditure in the Yangtze River Delta region from 2012 to 2021 was 0.251,which was less effective but on the rise overall.There were notable variations in the efficiency of government health expenditure between different regions,showing a spatial distribution pattern of"high in the south and low in the north,high in the east and low in the west",and a spatial evolution characteristic of the gradual widening of the gap between the north and the south.The global Moran's I coefficient for the efficiency of government health expenditure in the Yangtze River Delta region was positive(P<0.001),indicating a significant positive spatial correlation.Fiscal revenue decentralization had a negative impact on the efficiency of government health expenditure,with a total effect coefficient of-4.008.In contrast,fiscal expenditure decentralization and fiscal self-sufficiency rate showed opposite results,with total effect co-efficients of 5.504 and 3.568,respectively.Conclusion:There is still considerable room for improvement in the efficiency of gov-ernment health expenditure in the Yangtze River Delta region.Narrowing regional disparities and emphasizing spatial effects are cru-cial to the integration of healthcare in the Yangtze River Delta region.It is recommended to promote the sharing of regional medical resources,leverage the bench-marking effect of local governments,and improve the fiscal decentralization system to enhance the o-verall efficiency of government health expenditure.
