Urban Land Use Efficiency and Contributing Factors in the Yangtze River Delta Under Increasing Environmental Restrictions in China
文献摘要：
Evaluating urban land use efficiency(ULUE)provides insights into the interactions between land use systems and their ex-ternal environment.Specifically,changes in ULUE are important for monitoring urban transformation in developing countries.In this study,using a traditional input-output index model,we incorporated slack-based measurements and undesirable outputs into a SBM-UN(slack-based measure-undesirable)model to investigate ULUE within the context of increasing environmental restrictions in China.The model was used to estimate the ULUE of 26 cities in the highly developed urban agglomeration of the Yangtze River Delta from 2000 to 2018.The average ULUE in the Yangtze River Delta was relatively low compared to that of developed city regions in the European Union(EU)and North America and exhibited a U-shaped curve over the study period.Incorporating undesirable outputs,such as envir-onmental pollution,into the model reduced ULUE by 19.06％.ULUE varied spatially,with the kernel density estimation exhibiting a bimodal distribution.Efficiency decomposition analysis showed that scale efficiency made a greater contribution to ULUE than pure technical efficiency.Based on our findings,recommended approaches to improve ULUE include optimizing factor allocation,reducing undesirable outputs,and increasing the effective output per land unit.The study suggests that ULUE and the SBM-UN model are useful planning tools for sustainable urban development.
