摘要
绿色城市更新是推动城市高质量发展的重要行动。本文采用超效率SBM模型测度中国绿色城市更新效率,利用Dagum基尼系数和Kernel核密度估计法分析中国绿色城市更新效率的空间差异及分布动态演进,探究中国全域及四大地区绿色城市更新效率的驱动因素。研究表明:(1)2011—2023年中国绿色城市更新效率呈现升高的趋势,中国绿色城市更新效率在不同区域之间存在显著差异,东北地区效率最高,中部最低。(2)中国绿色城市更新效率空间差异化逐渐缩小,中部与东北地区绿色城市更新效率的区域间差异最为显著,超变密度差异是绿色城市更新效率空间差异的主要来源。(3)政策经济密度和绿色创新转化效能是影响绿色城市更新的主导因子。中国绿色城市更新各区域存在差异并不是单一因素作用的结果,而是多种因素相互作用的结果。建议提升绿色城市更新效率应该既要从区域全局视角出发又要针对区域优势进行分类施策。
Green urban renewal serves as a crucial initiative to promote high-quality urban development.This study employs the super-ffciency SBM model to measure the fficiency of green urban renewal in China,utilizing the Dagum Gini coefficient and Kernel density estimation to analyze its spatial disparities and distribution dynamies.It further investigates the driving mechanisms of green urban renewal efficiency across China and its four major regions.The findings reveal that:Firstly,from 2011 to 2023,China's green urban renewal efficiency demonstrated an upward trend,with significant regional disparities.The Northeast region exhibited the highest fficiency while the Central region ranked lowest.Secondly,the spatial differentiation of green urban renewal efficiency has gradually narrowed,with the most pronounced inter-regional differences observed between the Central and Northeast regions.Hypervariable density diferences constitute the primary source of spatial disparities in renewal efficiency.Thirdly,policy economie density and green innovation transformation eficiency emerge as dominant factors infuencing green urban renewal.Regional variations in China's green urban renewal result from the combined effects of multiple interacting factors rather than single determinants.The study recommends that enhancing green urban renewal efficiency should simultaneously adopt a holistic regional perspective and implement diferentiated strategies leveraging regional advantages.
