摘　　要：生态福利绩效是衡量区域绿色发展的新指标。考察城市生态福利绩效的空间分布和变异性特征,对城市生态资源进行分区规划和管理至关重要。基于投入-产出理论,纳入环境污染非期望产出,采用超效率SBM模型评价了长江经济带城市生态福利绩效,分析了其空间分布特征,并就其空间变异性进行了建模分析。结果表明:(1)长江经济带城市生态福利绩效自2016年发展规划实施以来显著提升,增幅达33.3%。(2)城市间生态福利绩效呈现明显的空间集聚趋势,特别是长三角地区绩效整体水平显著提升。(3)城市生态福利绩效的空间相关性范围随时间推移逐渐减小,但变异程度保持相对稳定,需要加强生态环境治理,确保绩效持续提升。基于以上结论从生态环境治理,生态资源配置与机制构建以及城市间合作提出对策建议。Ecological welfare performance serves as a novel indicator for gauging regional green development,and is pivotal for scrutinizing the spatial distribution and variability characteristics of urban ecological welfare performance to facilitate zoning planning and management of urban ecological resources.Drawing upon input-output theory and incorporating undesired outputs of environmental pollution,we assessed the ecological welfare performance of cities within the Yangtze River Economic Belt utilizing the super-efficient SBM model.Subsequently,we analyzed its spatial distribution characteristics and conducted modeling analysis on the spatial variability.Our findings revealed that:(1)The ecological welfare performance of cities within the Yangtze River Economic Belt witnessed a significant increase of 33.3%since the inception of the development plan in 2016.(2)There existed a pronounced spatial clustering trend in ecological welfare performance among the cities,and is particularly notable in the marked enhancement in overall performance observed in the Yangtze River Delta region.(3)The spatial correlation range of urban ecological welfare performance gradually diminished over time,while the degree of variability remained relatively stable.Hence,it is imperative to reinforce ecological environmental governance to sustain the upward trajectory of performance.Drawing from the aforementioned conclusions,we propose countermeasures that focus on ecological environmental governance,ecological resource allocation and mechanism construction,and inter-city cooperation.
