基于生态效率的上海市经济发展模式判定及障碍因子诊断

JUDGMENT AND OBSTACLE FACTORS DIAGNOSIS OF SHANGHAI'S ECONOMIC DEVELOPING MODE BASED ON ECO-EFFICIENCY

文章基于生态效率模型,采用熵权TOPSIS法,对上海市2005—2014年间的资源效率、环境效率及生态效率进行了定量分析,并根据定量分析的结果判定其经济发展模式,最后运用障碍度模型对生态效率的障碍因子进行诊断。分析结果表明:1)就生态效率水平的变化轨迹而言,2005—2014年经历了低—中—高的变化过程,生态效率逐步趋好。2)就经济发展模式而言,2005—2014年上海市先后经历了传统的线性经济发展模式、末端治理型经济发展模式和循环经济发展模式,走的是一条ABD发展道路。3)就制约生态效率发展的障碍因子而言,平均障碍度排在前3的障碍因子由大到小依次为工业废气总排放效率(8.56%)、工业烟尘排放效率(8.53%)和生活用电效率(8.30%),上述指标是制约上海市生态效率发展的关键因子。

This paper applies coo-efficiency model and entropy weight TOPSIS to quantitatively analyze Shanghai＇s resource, environmental and ecological efficiency during 2005-2014, with the result used to judge its economic mode, and employs obstacle mode to diagnose its obstacle factors. Ecological efficiency level had undergone a low-medium- high change during 2005 to 2014, showing a rising trend. Economic mode along an ABD path had undergone a traditional linear mode, end treatment mode and recycling mode. The top three key obstacle factors against eco- efficiency are overall emission of industrial gas waste （ 8.56% ） , industrial fumes emission （ 8.53% ） and living electricity （8.30%）.
