Rapid industrialization leads to potential energy scarcity. The formulation of energy intervention can alleviate the economic losses caused by insufficient energy inputs in advance. In this study, the energy dependency and sensitivity quantification model (EDSQ) is firstly developed to evaluate the impacts of insufficient energy support on economic development under network-based perspective and sector-based perspective. A special case study for the Province of Shanxi, China, is conducted to illustrate the potential benefits of its use in the formulation of energy intervention for energy-dependent regions. Seven energy groups are explored to gain more insights into the impacts of specific energy groups on energy metabolism and the complicated interactions among sectors. It is found that the energy metabolism of Shanxi is under an unhealthy state. The internal flows are dominated by exploitation and competitive relationships, which is not conducive to effective energy metabolism. The hierarchy analysis indicates that the pulling force is hardly affected by the classified energy groups but the driving force is sensitive, which further reveals that the producers can choose different energy sources according to their production structure. Faced with potential energy scarcity, the shortage of coal may bring considerable economic losses. The energy intervention should be formulated for the sectors that are less dependent on energy. However, it is not recommended to curb energy use in the petroleum, coking, nuclear fuel processing and coal mining sectors, because their sectoral losses can impose significant losses to the entire network. Thus, the scientific results of this study can provide academic support for quantifying the impact of potential energy scarcity, and guide the formulation of energy intervention to achieve sustainable development for energy-dependent regions.
快速工业化导致潜在能源短缺。制定能源干预措施可以预先缓解因能源投入不足而导致的经济损失。本研究首先开发了能源依存度和敏感度量化模型(EDSQ),以从网络和部门两个角度评估能源支持不足对经济发展的影响。对中国山西省进行了一个特殊案例研究,以说明在制定针对能源依赖地区的能源干预措施时使用该模型的潜在好处。探索了七个能源组,以更深入地了解特定能源组对能源代谢和部门之间复杂相互作用的影响。研究发现,山西的能源代谢处于不健康状态。内部流动以开发和竞争关系为主导,不利于有效的能源代谢。层次分析表明,拉力几乎不受分类能源组的影响,但驱动力很敏感,这进一步表明生产者可以根据其生产结构选择不同的能源。面对潜在的能源短缺,煤炭短缺可能会带来相当大的经济损失。应针对能源依赖程度较低的部门制定能源干预措施。然而,不建议抑制石油、炼焦、核燃料加工和煤炭开采部门的能源使用,因为它们的部门损失可能会给整个网络带来重大损失。因此,本研究的科学结果可以为量化潜在能源短缺的影响提供学术支持,并指导制定能源干预措施,以实现能源依赖地区的可持续发展。
