Study On Decision Making Of Real Estate Project Construction Scheme On Consideration Of Both Efficiency And Effectiveness

At present,in the real estate project construction program evaluation method,the parameter method is often used for financial evaluation and economic analysis.However,when comprehensive evaluation methods such as fuzzy mathematics and analytics hierarchy process are adopted for analysis and research,evaluation and analysis are often carried out only from the perspective of investment efficiency,without fully considering the expected effect of investors and owners for comprehensive analysis.Based on this,this paper combines DEA method and combination weighting-TOPSIS method to carry out evaluation research on real estate project construction plan with consideration of efficiency and effect,in order to provide scientific decision basis for enterprises,the project that meets the investment decision requirements is finally selected through the construction plan decision evaluation and analysis.This paper first introduces the background status and theoretical basis,as well as the current real estate project construction program decision evaluation research situation and related concepts,and discusses the importance and necessity of the decision-making of real estate project construction scheme optimization,with the theory of project life cycle and sustainable development as the guiding theory.Secondly,on the basis of analyzing the applicability of DEA in the evaluation of investment efficiency of real estate project construction scheme,the overall evaluation process is introduced,and the evaluation index is selected to establish the evaluation system of investment efficiency based on the relevant research results of other scholars,and the DEA evaluation model of investment efficiency of real estate project construction scheme is finally constructed.Then,the expert consultation method is used to select the expected effect evaluation index to establish the evaluation system,entropy weight method and least square method are used to determine objective weight and subjective weight respectively to form comprehensive weight,and the expected effect evaluation model of the real estate project construction program is constructed on the basis of combination weighting-TOPSIS.Finally,the effectiveness and rationality of the evaluation system and model of investment efficiency and expected effect were verified by practical cases.In the four proposed investment projects,the project A of Changsha with high evaluation from both investment efficiency and expected effect was finally selected,and the evaluation results met the investment decision requirements.The evaluation results show that the evaluation system and model of real estate project construction plan with consideration of efficiency and effect can make investment for enterprises to select projects with higher efficiency and better effect,reduce the overall risk of the project,thereby improving the investment efficiency of the enterprise and enhancing the expected effect of the project.
