丝绸之路经济带节点省份能源生态效益动态分析——以甘肃省为例

Dynamic analysis on energy eco-efficiency of Economic Belt of Silk Road——In a case of Gansu province

社会经济发展对能源要素投入的依赖度很高,区域经济增长与能源消费呈正向相关关系。丝绸之路经济带的建设,一个重要目的是打通中国同中亚与西亚各国间的能源贸易通道,消除主要能源供给国对中国能源需求之间的屏障。在此背景下,对甘肃省2003—2013年能源生态效益进行评价,并与以往研究做对比,发现甘肃省能源生态压强从2003年的0.59倍增加到2013年的1.32倍;能源足迹盈余由2003年的0.722ha到2013年的-0.559ha;能源生态效益值虽然从2003年的5 093元/ha增长到2013年的10 489元/ha,但仍远低于同时期全国最优水平,处于弱可持续发展区。

The social and economic development has a high dependence on energy input,and the regional economic growth has a positive correlation with energy consumption.Construction of the Silk Road Economic Belt,whose important purpose is exploring the energy trade routes through China to the countries of Central Asia and West Asia,will eliminate most of barriers between main energy supply countries and Chinese energy demand.In this context,the energy eco-efficiency of 2003—2013in Gansu province was evaluated,and compared with the previous studies.The results reveal that the energy ecological pressure in Gansu province increases from 0.59 times in 2003 to 1.32 times in 2013.Energy footprint surplus of 2003—2013changes from 0.722 ha to-0.559 ha.Although the energy ecological benefit value increases from 5 093yuan/ha of 2003 to 10 489yuan/ha of 2013,it still far below the national optimum level of the same period,i.e.in a weak sustainable development zone.
