生态效率是衡量经济系统和环境之间相互关系的核心指标。文章在对传统的 DEA 模型修正的基础上,采用非径向、非角度的 SBM 模型对安徽省9个城市煤炭产业生态效率进行了测算,并给出了相应的改善途径。研究显示:2003-2012年期间,安徽省煤炭产业生态效率整体低下,9个城市均未达到生态有效。投入产出的冗余率均处于较高水平,淮南和淮北表现较为良好,但仍存在改进空间;其他地区,尤其是阜阳、亳州等地,需重点改进。最后,文章提出了树立正确的技术创新意识、拓展资金融入渠道等提高安徽省煤炭产业生态效率的针对性建议。
生態效率是衡量經濟繫統和環境之間相互關繫的覈心指標。文章在對傳統的 DEA 模型脩正的基礎上,採用非徑嚮、非角度的 SBM 模型對安徽省9箇城市煤炭產業生態效率進行瞭測算,併給齣瞭相應的改善途徑。研究顯示:2003-2012年期間,安徽省煤炭產業生態效率整體低下,9箇城市均未達到生態有效。投入產齣的冗餘率均處于較高水平,淮南和淮北錶現較為良好,但仍存在改進空間;其他地區,尤其是阜暘、亳州等地,需重點改進。最後,文章提齣瞭樹立正確的技術創新意識、拓展資金融入渠道等提高安徽省煤炭產業生態效率的針對性建議。

Eco-efficiency is a core indicator to measure the relationship between the economic system and the environment.In this paper,a non-radial non-oriented SBM model of DEA is applied to meas-uring the eco-efficiency of the coal industry of nine cities in Anhui Province from 2003 to 2012.The results show that the eco-efficiency of coal industry in Anhui Province presents low developing trend, with all the nine cities not reaching optimization level.Besides,the redundancy rates of the inputs and outputs are in high levels.Huainan City and Huaibei City perform better but still need to be im-proved.Others,especially Fuyang City and Bozhou City,need to pay more attention to it.Some measures to improve the eco-efficiency of coal industry in Anhui Province are also put forward,inclu-ding establishing correct technological innovation consciousness and expanding approaches of finan-cing.
