Research On Investment Decision Evaluation Of Elderly Real Estate Project Based On Combination Weighted-gray Correlation Analysis

Nowadays,the trend of aging in China's society is becoming more and more serious.In order to eliminate the negative effects brought about by the phenomenon of aging as much as possible,the old-age real estate came into being.Compared with other ordinary real estate businesses,pension real estate has many characteristics such as many interfaces,complicated,long construction period,and large capital and personnel input.Based on these characteristics,the investment decision-making link that is the core of the life cycle of the old-age real estate project is more risky,complex and comprehensive.To this end,as the main body of investment decision-making,the decision-making personnel of the pension real estate investment function department adopts a reasonable,comprehensive and scientific evaluation system to comprehensively consider each scheme and select the optimal scheme.Especially important,the process will directly affect the success or failure of an old-age real estate project.Therefore,through the combing of literature research,expert consultation,and the investment decision-making problem of the old-age real estate project,this paper constructs the investment decision-making model of combined empowerment-grey correlation analysis method,and applies it to verify its applicability and scientificity.This paper firstly reviews the relevant researches on elderly real estate and real estate investment decisions at home and abroad,and expounds the related concepts of pension real estate and enumerates the theoretical methods related to this paper.It also introduces the development of China's elderly real estate and the stakeholders in the investment decision-making process.Secondly,on the basis of literature review and expert consultation,the basic principles of constructing the evaluation index system are followed,and a preliminary evaluation index system for investment decision-making of elderly real estate projects is established.Then,the expert consultation method is used to screen and screen the index factors in the indicator system,and finally determine the framework of the evaluation index system,and conduct detailed research and analysis on various index factors in the system.Then,the combination weighting method combined with AHP analytic hierarchy process and entropy weight method is used to determine the index weight.Based on this,the grey relational analysis method is used to comprehensively evaluate each candidate investment plan,and the investment decision model of the elderly real estate project based on combined weight-grey correlation analysis method is constructed.Finally,in order to verify the applicability and scientificity of the model,it is applied to the specific practice of investment decision-making in a real estate enterprise to verify the model.Through the research and analysis of this paper,the combined weighting method in this paper can effectively consider the subjective and objective factors,avoid the subjective judgment during the evaluation period,fully reflect the internal logical relationship between the indicators,and comprehensively evaluate the project.Through the analysis of the application results of the actual case model,this paper verifies that the established elderly investment decision model based on the combination weighting-gray correlation analysis method is scientific and applicable in the actual decision-making process,therefore,it provides a scientific and reasonable investment decision reference for the pension investment decision makers.
