| The ageing of society and the increasing number of disabled elderly people are far beyond the capacity of traditional families to afford old age for the common family model "4 +2 +1".The continuous development of social institutions for the elderly has gradually solved the existing burden of the elderly,and has received strong support from the state in terms of policies."There is no medical care" is the norm of existing old-age institutions.Under the premise of meeting old-age care,medical conditions are relatively simple,and the needs of old-age care can not be truly met.The combination of medical and nursing programs can effectively solve this problem.At present,the combination of medical and nursing projects has the characteristics of huge investment and long cycle.It can not afford the construction operation of the project and the project operation efficiency is low.With the gradual participation of social capital in the construction of medical and nursing projects,PPP model has received extensive attention.According to the present situation analysis of PPP project,in the process of designing government and social capital contract,unreasonable risk sharing will lead to many problems in the construction and operation of the project.Therefore,effective and reasonable risk sharing has practical significance for the construction of the combined medical and nursing projects under the PPP model and the solution of social pension problems.In view of this,a practical study on risk sharing in the context of medical care and PPP projects is carried out using the Shapley value method and the revision of risk sharing.Through the research of the related documents such as medical and health combined PPP project and PPP project risk management,it is concluded that the risk sharing research of medical and health combined PPP project in China is not perfect.Further in-depth research is therefore needed.The first part analyzes the research background and significance of the thesis.Combined with domestic literature,it is found that China’s medical and health combined PPP project is an emerging project,and the research content is relatively small.The research focuses on the qualitative study of the risk sharing of medical and health care combined withPPP projects,and the quantitative study is relatively scarce.The second part defines the concept of the specific medical and health combined PPP project,and details the relevant theories such as PPP project risk management and PPP project risk sharing.The third part first uses WBS-RBS method to identify the risk factors of the medical and health combined PPP project,and then conducts a questionnaire survey on the risk factors of the project,and preliminary shares the key risk factors analyzed.The fourth part,based on the principle of risk sharing,establishes the revised index system of risk sharing of medical and health care combined with PPP project.The risk sharing model is constructed by combining the Shapley value method with the modified index system.In the fifth part,the risk sharing model built above is applied to the project of medical and health care combined PPP in A county.Taking the example of the unhealthy risk of medical and health supervision and evaluation system as an example,the specific risk loss ratio that the participating parties should bear in the project is obtained.Finally,all the work of the paper is summarized,and the prospect of future related research is put forward. |
