摘　　要：碳生产率能将低碳经济的两大目标融为一体,工业部门作为能源密集型部门,是二氧化碳排放的主体,其碳生产率的变化深刻影响着中国整体碳生产率的格局。目前,大部分学者都用GDP与二氧化碳排放量的比值作为衡量碳生产率的指标,然而二氧化碳排放空间作为一种投入要素,其产出除了经济绩效外还包括环境、就业等综合绩效。本文基于广义碳生产率的概念,通过对前沿分析方法的比较,选择基于方向性距离函数的DEA方法,测算了中国工业部门各细分行业从2004-2009年的广义碳生产率指数,并对其变化进行了分解。结果表明:(1)中国工业部门广义碳生产率指数整体小于1,说明广义碳生产率水平整体上存在下降的趋势;(2)引致工业部门广义碳生产率指数整体小于1的主要原因是技术效率和规模效率低下。At present, the ratio of GDP and carbon emissions is usually used as an indicator to measure carbon-productivity. However, as a input factor, the output of carbon emissions space not only includes economic performance but also includes the environment, employment and other integrated performance. Under the concept of generalized carbon productivity, using the data from the China Statistical Yearbook, the generalized carbon-productivity index from 2004-2009 of Chinese industrial sector is evaluated, based on directional distance function and data envelopment analysis method. The results indicate that, firstly the overall carbon-productivity index of Chinese industrial sector is less than 1, which means that there is a downward trend of generalized carbon productivity. Secondly, downward trend is mainly due to the low technical efficiency and scale inefficiency.
