江西省煤炭产业生态效率评估(2005～2014年)

Eco- efficiency evaluation of coal industry in Jiangxi Province from year 2005 to 2014

如何让江西省煤炭产业快速提高其生产效率,是广大学者和管理者们关注的热点。本文以江西省煤炭产业为研究对象,采用数据包络分析方法开展江西煤炭产业生态效率评估,研究结果如下:(1)从2005到2014年,江西省煤炭产业生态效率提升趋势明显。(2)基于投入冗余的分析表明,江西省煤炭产业生态效率的主要影响因素为年综合能源消耗量、工业废气排放量。(3)基于超效率DEA模型的分析表明,2013年为最优。

How to make the coal industry in Jiangxi Province improve the Eco- efficiency rapidly is the focus for the scholars and managers. The results are as follows：（ 1） From year 2005 to 2014,the trend of eco- efficiency of coal industry in Jiangxi Province has been improved obviously.（ 2） Based on the analysis of input redundancy,the main factors influencing the eco- efficiency of coal industry in Jiangxi Province are annual comprehensive energy consumption and industrial waste gas emission.（ 3） The eco- efficiency value of year 2013 is the best based on super efficiency DEA model.
