Fuzzy evaluation of comprehensive benefit in urban renewal based on the perspective of core stakeholders

Abstract This paper chooses government, resident and developer for the core stakeholders of the urban renewal who can affect the realization of the urban renewal objectives during the whole life cycle of the urban renewal construction. Based on the analysis of literature summary about urban renewal, this paper confirms 30 influence factors of comprehensive benefits in urban renewal through the questionnaire. The evaluation index system of 16 factors containing three subsystems of government benefits, resident benefits and developer benefits is established through factor analysis theory. Entropy method was then used to assign weights on criteria and macro-criteria. The weights of government, residents and developers are respectively 0.343, 0.386, 0.271. Then an evaluation model of urban renewal comprehensive benefit is put up. Fuzzy theory is used to calculate the evaluation values of Lieder village renewal in Guangzhou and the evaluation result shows that the comprehensive benefit evaluation of Lieder village renewal is good. The result is accord with actual. It has a certain practical value for the evaluation model used on the comprehensive benefit evaluation of urban renewal.
