利用1978～2010年样本数据,通过分位数回归模型详细研究了各因素对能源效率在不同分位点上的影响变化。研究发现,能源价格对能源效率的影响随着能源效率的提高呈U型分布;产业结构的变动只有在能源效率较低时才会对其产生明显的影响作用;能源效率低下时,技术进步会促进能源效率的提高,而能源效率较高时,技术进步存在“回弹效应”;城市化水平的提高有利于能源效率的提高,并且这种作用随着能源效率的提高而不断增强。最后,根据实证分析的结果给出了相关建议。
Using the sample data from 1978 to 2010, the influence of different factors on energy efficiency at different sub-sites was studied in detail by quantile regression model. The study found that the impact of energy prices on energy efficiency was U-shaped with the increase of energy efficiency. The change of industrial structure only had a significant effect on energy efficiency when it was low. When the energy efficiency was low, Promote the improvement of energy efficiency, and the higher the energy efficiency, there is a “rebound effect” in technological progress; the improvement of urbanization level is conducive to energy efficiency improvement, and this role is enhanced with the improvement of energy efficiency. Finally, based on the results of empirical analysis, some suggestions are given.
