| 摘 要： | 随着中国各省份间能源生产、消费的关联日益紧密,隐含在商品贸易中的能源流动有助于平衡中国总体能源供需,但跨省能源流动伴随的能效冗余问题也逐渐凸显。本文通过刻画中国2007年和2015年省际隐含能源流动,测度中国隐含能源流动的能效冗余,主要结论如下：①中国区域间隐含能源流动主要从华北、华东、华中、东北地区流向华南、西北、西南地区;②中国大部分省市的隐含能源流动逐渐由消费驱动转向投资驱动,北京、上海、广东等经济发达地区的隐含能源流动仍以消费驱动为主;③中国整体直接能源利用大于完全能源需求,但是近年来部分省份直接能源利用与完全能源需求之间的缺口有所缓解;④中国整体隐含能源冗余情况有所改善,但河北、辽宁、山西等隐含能源供给省份的能源利用效率仍有待提升。本文结果有助于针对性地辨识低能效省份的能源效率、降低全供应链的能效冗余,对中国各省份间的高效能源配置利用具有借鉴意义。 |

| Abstract: | With the gradual strengthening of China’s energy production and consumption linkages, the energy flows embodied in commodity trade would balance China’s overall energy supply and demand, but energy efficiency redundancy has gradually emerged along with interprovincial energy flows. This study depicted China’s multiprovincial embodied energy flows and measured the energy efficiency redundancy. The main conclusions are as follows: (1) China’s multiregional embodied energy flows were from North China, East China, Central China, and Northeast China to South China, Northwest China, and Southwest China; (2) The main driver of energy demand in most regions of China was gradually shifting from consumption to investment, but the total energy demand in economically developed provinces/municipalities such as Beijing, Shanghai, and Guangdong was still driven by consumption; (3) China’s direct energy use was greater than total energy demand, but the gap between direct energy use and total energy demand in some provinces have narrowed in recent years; (4) China’s energy efficiency redundancy has improved, but the energy utilization efficiency of Hebei, Liaoning, and Shanxi Provinces, as embodied energy suppliers, still needs to be improved. The results of this study have practical implications for identifying the energy efficiency of targeted provinces and lower the energy efficiency redundancy of the entire supply chain, which is essential for improving multiregional energy allocation and utilization efficiency in China. |
