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.
