Research On Performance Evaluation Of Safe Housing Project Based On DEA Method

Since the reform of the housing system in 1998,the housing problem has always been a hot spot of concern to all sectors of society.In the current high housing prices,the basic housing needs of many low-income social groups are not met.In order to solve the problem of housing at the bottom of the population,the government has intensified the construction of safe housing projects in recent years.Especially during the "Twelfth Five-Year Plan" period,the number of government-built safe housing units reached 36 million,and the coverage of protection increased to about 20%.Along with the completion of the safe housing project,the supporting facilities are not perfect,the occupancy rate is not high,and the residents' satisfaction is low.A series of problems are becoming more and more obvious,making the construction of the safe housing project less than expected.As a public investment project for public investment,safe housing is related to the interests of the bottom masses of each society.The performance evaluation of the safe housing project can objectively reflect the problems existing in the project,and provide specific suggestions for improving the performance of the safe housing project and guiding the government to make relevant policy adjustments.Based on the relevant research results of foreign public project performance evaluation and domestic safe housing project performance evaluation,this paper combines the theory of social security,housing filtering and social satisfaction,combined with the status quo and characteristics of China's safe housing policy,and evaluates performance.The DEA method was compared for feasibility analysis.By combing the relevant research literature and referring to the expert interview opinions,the input and output index system of performance evaluation of safe housing projects was screened,and the basic model of DEA method was compared and analyzed.The input-oriented CCR model was selected to construct the safe housing project performance evaluation model.21 typical safe housing projects in YZ City were selected as empirical research samples.Through field visits,satisfaction surveys and access to relevant official websites to obtain indicator data,software parameters were set,and DEA model was used to obtain comprehensive coverage of 21 safe housing projects.Technical efficiency,pure technical efficiency,scale efficiency.According to the results of the operation,21 safe housing projects were analyzed for effectiveness,stability analysis,efficiency value analysis,scale profitability analysis,DEA invalid projection analysis,and indicator importance analysis.The analysis shows that among the 21 decision-making units,14 decision-making units such as Lianyi Nanyuan are effective.Among the 14 effective decision-making units,the Shanwan Garden project has the strongest effective stability.Among the three types of guarantees,the comprehensive technical efficiency,effective stability and scale efficiency of public rental housing are the highest The three key factors affecting the effectiveness of safe housing are educational facilities,commercial facilities,and public transport convenience.According to the analysis results,the rationality of the construction of the performance evaluation model of the safe housing project was confirmed,and the construction of infrastructure such as educational facilities,commercial facilities and public transportation was strengthened.The construction of public rental housing was strengthened.The government should pay attention to the construction of safe housing and improve the utilization of input resources and other targeted recommendations.
