新疆工业全要素能源效率研究

A Study of Total - factor Energy Efficiency in Industry in Xinjiang

本文运用固定规模报酬CRS模型,从部门角度对全国2001年—2010年工业全要素生产率进行了测算,并对新疆在全国所处水平进行分析;然后,以1994年—2010年新疆工业行业数据为基础,测算新疆工业各行业的能源效率;最后运用Tobit模型,分析了新疆工业能源效率的影响因素。通过分析发现:第一,新疆工业部门能源效率排全国第29位,且效率呈递减趋势,节能潜力巨大;第二,在1994年—2010年间,36个工业行业能源的平均值为0.364,不存在收敛趋势;第三,企业规模对新疆工业能源效率具有显著性正向影响,煤炭消耗占比、外商直接投资水平对新疆工业能源效率具有显著性负向影响,而产权绩效、用电量占能源总消耗量的比例对新疆工业能源效率影响不显著。

By using the Constant returns to scale CRS model, China＇ s 2001--2010 Industrial Total Factor Productivity was calcu- lated from a sector perspective, and the level of Xinjiang in China was analyzed, Then based on the Industrial Data in Xinjiang from 1994 to 2008, we estimates Xinjiang industrial energy efficiency; Finally, we use the Tobit model to analyze the factors af- fecting the efficiency of industrial energy in Xinjiang. The analysis found that. （ 1 ） Xinjiang＇ s industrial sector energy efficiency ranked 29 in China, and efficiency showed a decreasing trend, the energy -saving potential is huge. （2） the size of enterprises has a significant positive effect to the industrial energy effieieney of Xinjiang, while the portion of the consumption of coal, the level of foreign direct investment has a significant negative effect to the industrial energy effieieney of Xinjiang. However, the property performance and the proportion of electricity consumption is not significant to the industrial energy efficiency of Xinjiang. Fi^aUy, some suggestions are given to the industrial development in Xinjiang.
