中国生态治理效率及其变动

    China's Ecological Management Efficiency and Changes

    • 摘要: 生态治理是生态文明建设的关键环节,提高生态治理效率不仅有利于提高生态文明建设的质量和效益,也是主动适应新常态的重要着力点.从生态破坏和环境吸收能力两个维度,建立包括水、空气、废弃物、垃圾、绿地、森林、湿地、草原、土壤等子维度的生态质量综合评价体系,采用"纵横向拉开档次"评价方法刻画2003-2012年中国生态质量现状,引入效率理论构建ISBM模型和ISBM-Luenberger生产率指数对中国生态治理效率及其变动进行分析.研究显示:2003-2012年中国生态治理效率平均值为0.276,有待改善;技术进步和规模效率平均每年上升0.32%、0.19%,是中国生态治理效率变动的主要驱动因素,而纯效率则平均每年下降0.32%.

       

      Abstract: Ecological management is the key to ecological civilization, and improving efficiency of ecological management will not only help to increase the quality and benefit of ecological civilization, but also serve as an important focal point for adaption to the new norm. An ecological evaluation system was established in this paper from two dimensions of ecological destruction and environmental absorption,including water,air,waste,garbage,green,forest,wetland, grassland,soil,etc.,using scatter degree method to describe the ecological status from 2003 to 2012 in China. The efficiency theory were introduced to take a comprehensive analysis of ecological management efficiency in China by ISBM model and ISBM-Luenberger productivity index. Studies showed the average value of ecological management efficiency was 0.276 from 2003 to 2012;there was huge room for improvement;the changes in technical progress and scale efficiency were increasing 0.32% and 0.19% per year, which were the main driver for China's ecological management TFP changes, while pure efficiency was decreasing 0.32% per year.
