Objective To analyze and compare the urban-rural difference of health resource allocation of maternal and child health institutions in Sichuan province. MethodsGini coefficient and agglomeration degree was used to analyze the equity of health resource allocation of maternal and child health institutions in Sichuan province. ResultsThe number of maternal and child health institutions per 10 000 population in rural areas was higher than that in urban areas, while the hospital beds and health workers per 10 000 population was lower. In terms of population-based Gini coefficient, the value of three type of health resources of maternal and child health institutions in Sichuan Province were lower than 0.4, indicating a good equity, however, the value of institutions and health workers in urban areas were lower than those in rural areas, the value of hospital beds were higher than those in rural areas. In terms of the difference between HRAD and PAD, there were great differences in the population-based accessibility of health resources of maternal and child health institutions in Sichuan province, relative excess and relative deficiency coexisted in different city (state). Moreover, there were differences in population-based accessibility to health resources of maternal and child health institutions between urban and rural areas in each city (state). ConclusionThere are obvious urban-rural and regional differences in health resources allocation of maternal and child health institutions in Sichuan province. Social factors such as population, geographical area and service radius should be comprehensively considered according to the real needs in the planning of rational health resources allocation of maternal and child health institutions.
