Evaluation On The Efficiency Of Investment Reconstruction In Old Residential Areas From The Perspective Of Social Benefits

Reconstruction of old residential areas is an important of intensive use of urban land and a major livelihood project to improve living environment and living standard.It is of great significance to evaluate the efficiency of reconstruction investment for improving the living conditions of residents,improving the living conditions of middle and low income groups,promoting the construction of harmonious communities and improving the overall image of the city.And the evaluation of the investment efficiency of the renovation of old residential areas is the prerequisite for the promotion and management of the renovation of old residential areas,as well as the necessary basis for government decision-making.But at present,the efficiency of the old residential district has not formed a relatively sound evaluation index system,and the social benefits generated by the renovation of the old residential district are less concerned.Accordingly,the research focuses on "Evaluation of investment efficiency in renovation of old residential areas from the perspective of social benefits",and the specific research contents and conclusions are as follows:First First of all,according to the theory of human settlement environment science and social benefit is the basis of related literature,follow the three principles of constructing the evaluation index system from the Angle of input-output chosen investment as input index,and the community and urban residents,three dimensions of a total of 19 output indicators,old village renovation investment efficiency evaluation index system,The specific meaning and measure method of each index are expounded respectively.Then,through the comparison and analysis of the comprehensive evaluation methods,and combined with the characteristics of the old community reconstruction,the government investment as the input index,residents,communities and cities selected 19 indicators as the output index;The output-oriented BCC model is used to evaluate the investment efficiency of the renovation of the old residential area.On this basis,the super-efficiency BCC model is used to further analyze the renovation efficiency of the old residential area that has reached the frontier.Finally,xi "an old city as research area,based on the construction of old village renovation investment efficiency evaluation index,design questionnaire,empirical analysis,based on the model of evaluation of efficiency value and slack variable as a result,the analysis influence the efficiency of the old village transformation investment,puts forward Suggestions for the improvement of old village renovation investment efficiency.The evaluation method of investment efficiency in the reconstruction of old residential areas has provided a set of scientific and reasonable evaluation methods for the evaluation of investment efficiency in the reconstruction of old residential areas in other areas of our country,which has a certain reference significance.It provides a practical basis for improving the efficiency of old residential areas,improving residents’ living environment,promoting the harmonious development of the community and enhancing the image of the city,and has a certain reference value for the research on the investment efficiency of old residential areas reconstruction from the perspective of social benefits.
