摘要
城市建设用地生态效率是城市建设用地在生态建设方面产出与投入的比值,是衡量城市发展品质的重要内容。采用武汉城市圈2006~2015年的面板数据,通过SBM-DEA模型和Malmquist指数对武汉城市圈建设用地生态效率进行测算研究,并通过Tobit模型定量分析了各要素对武汉城市圈建设用地生态效率影响程度。研究结果表明:(1)2006~2015年武汉城市圈建设用地的生态综合效率值总体上呈现螺旋上升的状态,分解效率中纯技术效率是影响综合效率的关键因素;(2)城市圈建设用地生态演变过程可以划分为早期低效阶段、快速提升阶段、不稳定转型阶段;(3)武汉城市圈建设用地生态效率的增长阻力主要是由于技术进步的制约;(4)生态压力、工业发展水平和生态技术水平对城市圈建设用地生态效率产生显著负向影响,而生态投入和产业结构对城市建设用地生态效率产生显著正向影响。
The eco-efficiency of urban construction land is the ratio of output and input of ecological construction,which is an important content to measure the quality of urban development. This paper calculated the eco-efficiency of construction land using the SBM-DEA model and Malmquist index model based on the panel data of Wuhan City Circle during 2006 to 2015. The influence degree of various factors on the eco-efficiency of construction land was analyzed in Wuhan City Circle using the Tobit model. The results showed that：（ 1） The ecological comprehensive efficiency of Wuhan City Circle construction land during 2006 to 2015 showed a spiral upward trend in general, and the pure technical efficiency was the key factor affecting the comprehensive efficiency in decomposition efficiency.（ 2） The ecological evolution of urban construction land was divided into early inefficient stage,rapid returned stage,unstable transition stage.（ 3） The growth of eco-efficiency of construction land in Wuhan City Circle was mainly due to the improvement of technological progress.（ 4） The ecological pressure,the industrial development level and the ecological technology have a significant negative impact on eco-efficiency of urban construction land,and the ecological input and industrial structure had a significant positive impact on the eco-efficiency of urban construction land.
