中文摘要：

在现有生态效率评价方法的基础上,构建了钢铁企业生态效率评价的投入产出指标体系,并将污染物排放作为一种非期望输入引入到数据包络分析模型中,运用该模型并基于CCR模型和BCC模型程序对太钢、宝钢和武钢企业2000年至2010年生态效率进行评价。通过Matlab6.5软件对数据进行了处理分析,结果表明,3家企业中太钢企业11年整体生态效率最高,其次是宝钢企业和武钢企业。

英文摘要：

Achieving ecological transformation of large steel enterprise has become the main development direction of steel industry or its large resource consumption and environment pollution.On the basis of existing ecological efficiency evaluation methods,the input and output index system for steel enterprise ecological efficiency evaluation was constructed,and pollutants as s kind of unexpected input was introduced into the data envelopment analysis model.Taigang,Baosteel and Wisco enterprises were evaluated on their 2000 to 2010 ecological efficiency by using the model based on the CCR model and BCC model program.The data processing by Matlab 6.5 software gava the evaluation results showing that Taigan＇s ecological efficiency was the highest of the three enterprises in the eleven years,followed by baosteel and Wisco.
