摘要
为评价城市更新综合效益,以石家庄为研究对象、郑州为参照,基于2014—2022年城市更新数据,构建经济效益、社会效益、环境效益指标体系,利用DEA和EWM法对该市城市更新综合效益进行定量分析。结果表明:石家庄在2015—2017年城市更新效益为非DEA有效,规模报酬系数呈递增的趋势,投入冗余率和产出不足率较大,而其他年份均为DEA强有效,规模报酬固定,投入冗余率和产出不足率处于正常水平;郑州各年度均为DEA强有效和规模报酬固定。2014—2018年石家庄的城市更新处于低投入、低产出;2019年处于低投入、高产出;2020—2022年处于高投入、高产出。石家庄的城市更新侧重社会权益,而郑州市侧重于经济效益。2014—2022年石家庄的城市更新综合效益评分呈不断上升趋势,2018年前增速较快,2019年后增速放缓;郑州综合效益评分与石家庄同样呈上升趋势,但评分值低于石家庄。最后提出了城市更新发展建议,以期为城市高质量发展提供有益参考。
To evaluate the comprehensive benefits of urban renewal,Shijiazhuang City was selected as the main research object,with Zhengzhou City serving as a reference.Based on urban renewal data from 2014 to 2022,an index system encompassing economic,social and environmental benefits was constructed.The comprehensive benefits of urban renewal in these cities were quantitatively analyzed using DEA and EWM methods.The results indicate that Shijiazhuang’s urban regeneration benefits from 2015 to 2017 are not DEA-efficient,exhibiting an increasing trend in the coefficient of returns to scale,and a large input redundancy and output insufficiency rate.In contrast,for the remaining years,the results demonstrate strong DEA efficiency with constant returns to scale,and input redundancy and output insufficiency rates remained at normal levels.Meanwhile,Zhengzhou exhibits strong DEA efficiency with constant returns to scale throughout the entire period.In terms of input and output levels,Shijiazhuang’s urban renewal from 2014 to 2018 is characterized by low input and low output.In 2019,it shifts to low input and high output,and from 2020 to 2022,transitions to high input and high output.Shijiazhuang’s urban renewal efforts primarily focuses on social rights and interests,while Zhengzhou emphasizes economic benefits.The comprehensive benefit score of urban renewal in Shijiazhuang shows an upward trend from 2014 to 2022,with rapid growth before 2018 and slower growth after 2019.Zhengzhou’s comprehensive benefit score follows a similar upward trajectory,although at a lower level than Shijiazhuang.Finally,suggestions for urban renewal development are provided to offer valuable insights for high-quality urban development.
