Construction And Simulation Of Public Health Care Service Sharing Model For Urban Agglomeration

With the development of regional transportation integration and the construction of urban agglomeration,cities are becoming increasingly connected with each other.At this stage,it is more important to optimize the layout of medical facilities in urban agglomeration.However,there are currently unbalanced problems in the number,level,and utilization rate of public health care service among cities in the city agglomeration.And it is necessary to realize the sharing of public health care service within the urban agglomeration in order to improve the efficiency of resource utilization in the urban agglomeration.In order to analyze the influence of various influencing factors on the sharing of public health care service in urban agglomeration,and then propose targeted priorities for promoting sharing,this study constructs a model of public health care service sharing in urban agglomeration and conducts simulation experiments.Firstly,a content analysis method is applied to identify the influencing factors of public health care service sharing in urban agglomeration.Secondly,a model of public health care service sharing in urban agglomeration is established,and the population self-coordination coefficient is newly introduced into the original Lotka-Volterra model to emphasize the influence of changes in internal factors on sharing,while external factors are quantified as population growth rate and inter-population interaction coefficient.Finally,the dynamic evolution results of public health care service sharing brought by changes of different influencing factors are explored through model solving and simulation experiments,and the roles of various influencing factors are compared.The study shows that:(1)in addition to the external support factors of urban agglomerations,the sharing of public health care service in urban agglomerations is also influenced by the cities’ own factors and other sharing cities;(2)the level of urban service,the economic level of cities,the willingness of cities to share,the cost of cities to share,and the degree of overlap of the ecological niche of shared resources have an impact on the equilibrium state of public health care service sharing in urban agglomeration and the time to reach equilibrium;(3)the equilibrium state of public health care service sharing in urban agglomeration is influenced by other sharing cities’ influencing factors,while the time to reach equilibrium is mainly determined by the sharing cities’ own influencing factors.This study makes up for the shortcomings of the current research on public health care service sharing in urban agglomerations,which is mostly at the level of individual status quo and ignores the sharing process,and emphasizes the influence of factors within the sharing city on public health care service sharing in urban agglomeration.At the same time,this study introduces the Lotka-Volterra ecological model,which is commonly used in the fields of innovation resource sharing and knowledge dissemination research,into the research field of urban agglomeration resource sharing,which not only enriches the research of urban agglomeration public health care service resource sharing model,but also develops the Lotka-Volterra model.
