京津冀、长江三角洲和珠江三角洲是我国沿海三大经济带。为了平衡区域发展，缓解能源压力，本文对2007 - 2012年京津冀、长三角和珠三角经济区内外的隐含能流进行了研究。运用多区域投入产出分析方法，分析了三大经济区的能源利用与经济发展、内部和外部隐含能流以及隐含能转移模式。结果表明，三大经济区的直接能源使用量约占全国总量的30%，而三大经济区的隐含能源使用量约占全国总量的75%。平均而言，JJ的人均能源使用量远远高于YRD和珠三角。JJ地区主要处于流出状态，而YRD和PRD是主要的内含能接收者，特别是来自河北和山东的内含能。在区域内联系方面，河北省与北京、河北省与天津、江苏省与上海和广东省与香港的联系是主要的隐含能流。这些研究成果和启示，对从系统的角度平衡能源基本供给，实现经济区能源协同发展具有一定的借鉴意义。(C)2020爱思唯尔有限公司保留所有权利。
The Jing-Jin-Ji (JJJ), Yangtze-River-Delta (YRD) and Pearl-River-Delta (PRD) are three major economic zones located in China's coastal areas. To balance regional development and alleviate energy pressure, this work explores the embodied energy flows inside and outside of the JJJ, YRD, and PRD economic zones from 2007 to 2012. By using the multi-regional input-output analysis, the energy use and economic development, the internal and external embodied energy flows, and the embodied energy transfer patterns of the three economic zones are analyzed. According to the results, the direct energy use of the three economic zones accounts for approximately 30% of the national total, while the embodied energy use of the three economic zones accounts for almost 75% of the national total. On average, the energy use per capita of JJJ is much higher than that of YRD and PRD. The JJJ region mainly remains in a flow-out state, while YRD and PRD are main embodied energy receivers especially from Hebei and Shandong. As for the intra-regional relations, the main embodied energy flows are identified from Hebei to Beijing, from Hebei to Tianjin, from Jiangsu to Shanghai and from Guangdong to Hong Kong. These results and implications in this work could help in the efforts to balance the basic energy supply and realize the synergetic energy development of the economic zones from a systematical perspective.
