A Study on the Comprehensive Evaluation on the Investment Benefits of Shenzhen Land Fund

A study on the comprehensive evaluation of the social, environmental and economic benefits of the land fund expenditure in Shenzhen was made based on fuzzy mathematics. To be more objective and more effective, the benefit evaluation procedure was improved in the following aspects. Firstly, the index system of comprehensive evaluation was established according to the main usage of the land fund in Shenzhen over the years. Secondly, with the assumption that the direct benefits and indirect benefits are different in proportion, the paper confirmed the weights of the main indexes according to the actual expenditure situation of the land fund. Finally, this paper regarded the relevant standard of developed country and urban construction in our country as the standard to confirm the grades of the indexes. The calculation result showed that there are 13 indexes regarded as excellent among the 24 indexes selected; the proportion changes of direct and indirect benefits have little influence on the total evaluation result; weights and evaluation grades of the social benefit were the highest in the 3 types of benefits, the economic benefit was the lowest; the weights and evaluation grades of municipal engineering were the highest, and accessory facility was the lowest.
