China is a large economy with unbalanced economic growth throughout different regions, posing a great challenge to allocating energy saving and carbon emissions reduction responsibilities. This paper applies the multi-regional input-output tables of China in 2007 and 2012 to evaluate the status of embodied energy consumption. The embodied energy transfer of eight regions in China is analyzed based on a demand-side perspective. Furthermore, the driving factors of embodied energy changes and the inequality at a regional level are explored via a structural decomposition analysis, which provides references for promoting regional energy development and adjusting the industrial layout. The results indicate that China's total embodied energy consumption increased from 2.06 billion tons of standard coal equivalent (tce) in 2007 to 3.46 billion tce in 2012. Specifically, embodied energy consumption is concentrated in the Central regions, consuming 710 million tce in 2012. In addition, a large proportion of energy produced in all regions is consumed locally, while the amount of transferred embodied energy is widespread across different regions. The economic scale is the primary driving factor of embodied energy consumption changes, and technological development has a noticeable effect on restraining energy consumption. Regarding the structural effect, significant differences exist in different regions and end-use sectors. In conclusion, the regional development policies aiming to optimize the industrial structure and strengthen energy technology improvement in dual-circulation development patterns are proposed.
中国是一个经济大国，各地区经济增长不平衡，这给分配节能降碳责任带来了巨大挑战。本文利用中国 2007 年和 2012 年的多区域投入产出表，评估了隐含能源消耗的状况。基于需求侧视角，分析了中国八个地区的隐含能源转移情况。此外，通过结构分解分析探讨了隐含能源变化的驱动因素及其区域层面的不平等，为促进区域能源发展和调整产业布局提供了参考。结果表明，中国的总隐含能源消耗从 2007 年的 20.6 亿吨标准煤当量增加到 2012 年的 34.6 亿吨标准煤当量。具体而言，隐含能源消耗集中在中部地区，2012 年消耗了 7.1 亿吨标准煤当量。此外，各地区生产的能源大部分在当地消耗，而转移的隐含能源则广泛分布在不同地区。经济规模是隐含能源消耗变化的主要驱动因素，技术发展对抑制能源消耗具有显著影响。关于结构效应，不同地区和终端用途部门存在显著差异。总之，提出了旨在优化产业结构和加强双循环发展模式下能源技术改进的区域发展政策。
