| 摘 要： 在采用Super-SBM-DEA方法评估和分析了2009—2014年中国30个省、自治区和直辖市生态环境效率变化趋势的基础上，构建了空间面板数据分析模型，从全国和分地区层面分别检验了用户终端电能替代对生态环境效率的影响，结果表明，从全国来看，提高终端能源消费中总的电能替代，特别是提高工业终端能源消费的电能替代水平能显著改善地区生态环境效率；分地区来看，电能替代对生态环境效率的影响存在较大的空间差异。东部地区提高总的以及工业用户和城镇居民终端能源消费的电能替代水平显著地有利于改善该地区的生态环境效率；而中部和西部地区提高总的和工业用户终端能源消费的电能替代水平显著地有利于改善该地区的生态环境效率。 |

| Abstract: By employing the Super-SBM-DEA method to evaluate and analyze the ecological efficiency and its trends of samples from 30 provinces, municipalities and autonomous regions in China from 2009 to 2014, the present study attempts to build spatial econometric model to test the effect of electric power alternation in user terminal energy consumption on the ecological efficiency at national and regional levels. The results show as follows. Improving the total electric power alternation, especially improving electric power alternation in industrial users’ terminal energy consumption can significantly promote the ecological efficiency at the national level. At the regional levels, electric power alternation affects the ecological efficiency in different regional levels respectively. The levels of total electric power alternation in the eastern region and the levels in industrial and urban residential terminal consumption are all beneficial to the improvement of the ecological efficiency of the area. |
