考虑科技投入的区域能源效率评价研究——以广东省为例

Research on Regional Energy Efficiency Assessment Considering the Input Factors of Science and Technology——Case of Guangdong Province

广东省能源效率的提升对其全面完成国家规定的节能任务以及有效缓解自身紧张的能源供需矛盾有着重要的战略意义。在考虑科技投入要素的情况下,对广东省各地区能源效率进行评价,研究发现广东省能源效率呈现出先下降后上升的整体趋势,各地区能源效率变化情况表现出各自的特点,并且考虑科技投入要素前后各地区能源效率值的变动程度也极具差异性。从理论及现实两个角度对其进行了解释。同时,为有效解决传统DEA评价结果中多个DEA有效单元的再排序问题,引入虚拟决策单元,进一步明确了广东省各地区能源效率的差异性及提升方向。

The improvement of energy efficiency in Guangdong Province has important strategic significance not only in completing the task of the state＇s energy conservation but also in the adjustment of the imbalance between supply and demand of energy. Considering the input factors of science and technology, the energy efficiency of vari- ous regions is evaluated in Guangdong Province and found that Guangdong＇s energy efficiency showed a first decreased and then increased overall trend and various regions also showed their own characteristics and that before and after the consideration of science and technology input factors the change of energy efficiency showed a great differences in the degree. And these issues from theoretical and practical point of view are explained. And meanwhile, the difference and promotion direction of energy efficiency are further clarified for the regions of Guangdong province by introducing virtual DMUs.
