摘要
基于DEA-Malmquist生产率指数,采用1992-2010年长三角地区能源消费与经济增长数据,实证测算了长三角地区全要素能源效率,并且进行全要素能源效率变动的分解,发现能源效率的变化趋势。实证结果显示:从时间维度看,1992-2010年长三角地区全要素生产率的水平是上升的。从TFP指数的进一步分解可以看出,技术进步指数上升,技术效率没有变化。因此,长三角地区全要素能源效率主要依赖于技术进步驱动,并且表现为阶段性波动,这与国家加大节能减排力度、区域产业结构调整、经济发展方式转变有关。从区域看,上海全要素能源效率指数最高,浙江次之;江苏全要素能源效率表现为负增长。基于以上分析提出一些对策和建议,包括加快能源技术进步;加快产业结构升级和转型,提高第三产业比重、加快产业转移和加大清洁能源和新能源的使用;加快体制创新,充分发挥市场机制的作用。
Based on DEA-Malmquist productivity index, this paper estimates the total factor energy efficiency of Yangtze River Delta region empirically by using the data of energy consumption and economic growth in this region from 1992 - 2010, and decomposes the changes in energy efficiency and finds the energy efficiency trend. The empirical result shows that, with time as a dimension, the total factor energy efficiency in Yangtze River Delta region increased in 1992 - 2010. From further decompose of TFP index, technological progress index rose, technical efficiency did not change. So the conclusion was that technological progress pulled the total factor energy efficiency in Yangtze River Delta region. The total factor energy efficiency showed a stage fluctuations, which was concerned the national energy saving and emission reduction efforts, regional industrial structure adjustment, economic development mode change relevant. With region as a dimension, the index of total factor energy efficiency in Shanghai was the highest, Zhejiang Province was the second while Jiangsu Province fell. Based on this results, this paper gives some measures and suggestions, including accelerating energy technology progress, speeding up the upgrading and transformation of the industrial structure, improving the proportion of the third industry, speeding up the industrial transfer, increasing the clean energy and new energy use, speeding up the system innovation, and giving full play to the function of market mechanism.
