摘要
本文以能源消耗量、劳动力、固定资产投资作为输入指标,以工业增加值、废气排放量作为输出指标,采用数据包络分析法(DEA)研究江西主要耗能行业的能源利用效率。实证研究表明,2009年江西主要耗能行业中有3个行业未达DEA总体有效,均为规模无效所致,因此在实际生产过程中,应注重投入规模。
Based on the energy consumption, labor, fixed asset investment as the input index, the Industrial value-added, gas emission as the output index, Using the Data Envelopment Analysis (DEA) to research the energy utilization-efficiency of Jiangxi main energy-consumption Industries. The research shows that 2009 three of Jiangxi main energy-consumption Industries failed to reach DEA total effectiveness due to the scale ineffectiveness. So It is import to pay attention to the input scale.
