摘要
生态效率表征了城市发展过程中经济效益和生态改进的双重提升,已经成为衡量城市可持续发展能力的重要指标。文章应用数据包络分析方法,对山东省2006-2008年间区域生态效率进行评价。结果表明:在此期间,山东省生态效率整体呈下降趋势,但下降速度缓慢;山东省区域生态效率呈显著的区域不平衡性,"一体两翼"布局中,"一体"紧密层及两翼中的北翼生态效率较高,而"一体"外围层及南翼生态效率较低;从总体来看,废水排放、固体废物排放、烟尘排放、粉尘排放成为影响全省生态效率的重要因素;通过引入虚拟决策单元,进一步明确了山东省各区域生态效率的差异性及提升方向。
Eco-efficiency describes the upgrade of economic and ecological improvements in cities＇ development,which has been an important index for the city sustainable development assessment.This paper assesses the regional eco-efficiency of Shandong province in 2006-2008 with DEA.The results are： the whole eco-efficiency of Shandong province drops slowly,and the eco-efficiency of defferent regions is unbalanced.In the arrangement of ＇One Body Two Wings＇,the close layer of＇One body＇and the North Wing have higer eco-efficiency,while the outer layer of ＇One body＇ and the South Wing have lower eco-efficiency.From the view of whole province,wastewater discharge,solid waste discharge,smoke emissions and dust emissions are the main factors restricting the eco-efficiency promotion of Shandong province.The difference and promotion direction of eco-efficiency are further clarified for the regions of Shandong province by introducing virtual DMUs.
