Urban Renewal Performance Evaluation Based on PCA-DEA Model: A Case Study of Guangzhou
Publication: ICCREM 2023
ABSTRACT
Based on the characteristics and current situation of urban renewal development in Guangzhou, this paper proposes an urban renewal performance evaluation system. Input indicators are fixed asset investment and financial expenditure, while output indicators are economic development, residents’ quality of life, social construction, and ecological environment. The combined PCA-DEA evaluation method is applied to comprehensively evaluate the performance of urban renewal work in Guangzhou from 2006 to 2020. The results show that for the 8 years between 2006 and 2020, comprehensive efficiency, pure technical efficiency, and scale efficiency achieved DEA validity, with constant scale payoffs. However, the other years did not achieve DEA validity, and thus, the distribution of slack variables in these years is analyzed to provide targeted improvement suggestions, aiming to promote the sustainable development of urban renewal work in Guangzhou.
