Study On The Risk Sharing Mechanism In Hospital PPP Project

The contradiction in quantity between the demand of rapid growth of hospital medical service and the insufficient supply of medical resources in public hospitals,and the quality contradiction between people’s diversified needs for medical services and the provision of a single medical service product from public hospitals,which are two main aspects of China’s current supply and demand contradiction in the hospital medical service.As a promising solution,PPP(public-private partnership)model has been introduced into the resource allocation of hospital medical service.However,the complex investment environment,many different participants and long operation cycle that make the risk of PPP project increase.So,reasonable allocation of risk among the participants has an important impact in the smooth progress of the project.And the paper holds that the research of risk sharing mechanism in hospital PPP project has important theoretical and practical significance.Firstly,this paper introduces the related concepts of the PPP project and elaborates the connotation of hospital PPP project risk allocation.The basic knowledge theory,such as set value statistical method,evolutionary game,random cooperative game and so on,is combed in this paper,which lays a theoretical foundation for the later research of the article.After identifying the characteristics of the hospital PPP project model,defines the subjects of risk sharing are public sector,social capital and medical operation organization,The evolutionary game model is constructed to deduce the risk sharing attitude of risk sharing entities,and the conditions for risk sharing entities to take risks are obtained.Then,the paper puts forward the identification method and path of risk factors,and set the value statistics method to quantify the impact of risk factors on the project。Secondly,the paper sorts out the risk sharing framework for hospital PPP projects.In order to maximize project benefits perspective,puts forward 6 principles of hospital PPP project risk sharing.The sharing process is divided into three stages with the combination of qualitative and quantitative sharing.n the first stage,the risk factors are shared qualitatively through the form of questionnaire;in the second stage,based on the risk preference coefficient of the project participants and the output benefit of theproject,a complete information dynamic game model of random cooperation between public sector,social capital and operation institutions is constructed,and the three party optimal value function equation is established on the payment matrix,and the Lagrange derivation solution is used,to get the proportion of risk sharing.In the third stage,the post evaluation of risk sharing results is put forward,followed by dynamic tracking and timely adjustment of risk sharing strategy.Based on the actual case of PPP project in ZP hospital,we use the results of this study to analyze.The evolution of risk sharing attitude of the NH city investment company as the representative of the public sector,social capital and medical operation institutions is simulated by MATLAB.The risk factors are qualitatively and quantitatively shared,and the best proportion of participants sharing risks was calculated.Finally,the conclusions of this paper are summarized,and suggestions for risk sharing in hospital PPP projects are put forward.The development of the hospital PPP project is prospected.
