Research On Investment Efficiency Evaluation Of PPP Project Of Combination Of Medical And Nursing Based On DEA Method

In the past two decades,the proportion of the elderly population in the national population has been increasing.The problem of population aging is a social problem that needs to be solved in our country.In recent years,in order to solve this problem,the Chinese government has issued a series of measures to actively deal with the aging,including encouraging social forces to participate in the elderly care services,and vigorously developing the PPP project of combination of medical and nursing.With the promotion of PPP project,the elderly can enjoy medical and pension services,and effectively solve the problem of "getting old before getting rich and providing for the aged with illness".In the process of the development of PPP project,whether there is a waste of resources,that is,whether all kinds of resources can be effectively used,is a problem worthy of discussion.Therefore,in this paper,we establish an appropriate input-output index system for the PPP project of combination of medical and nursing,and use the data envelopment analysis method to calculate,analyze and evaluate its investment efficiency.Firstly,the author introduces the research background,research purpose and research significance of the investment efficiency of the PPP project,and on this basis,puts forward the research content,research methods and technical route of this paper;Secondly,according to the content of this paper,the related concepts,theoretical basis and model methods are studied and discussed;Thirdly,by using the methods of literature research,frequency statistics and expert survey,this paper constructs the evaluation index system of the investment efficiency of the combination of medical and nursing PPP project,which includes four input indexes and three output indexes,a total of seven secondary evaluation indexes,including economic evaluation index and social evaluation index;Fourthly,the author introduces the basic model of DEA,and uses CCR model to calculate the comprehensive technical efficiency of the PPP project,and BCC model to calculate the pure technical efficiency of the project.The scale efficiency can be obtained by dividing the two;Fifthly,the author selects 20 PPP projects in the implementation stage of the PPP project library for empirical analysis,and calculates the comprehensive technical efficiency value,pure technical efficiency value,scale efficiency value and returns to scale of these projects,respectively.The calculation results show that the efficiency values of these projects are higher,that is,the resources invested in the PPP project of the combination of medical and nursing can be obtained To use effectively;This paper projects the non DEA effective PPP projects,analyzes their input redundancy and output insufficiency,and gives the specific improvement direction and adjustment value to make them DEA effective.According to the average adjustment degree of the indicators,it finds out four indicators that have a greater impact on the investment effectiveness of the PPP projects;On the basis of the projection results,starting from the above four evaluation indexes,the author puts forward specific countermeasures to improve the efficiency of project investment;In the last part,the author summarizes the whole paper,draws the research conclusion,and puts forward the prospect of the deficiencies in this study.This paper makes a comprehensive measurement,analysis and evaluation of the investment efficiency of the PPP project of the combination of medical and nursing,enriches the research results of the investment efficiency evaluation of such projects,and hopes to provide some reference for future research.
