Energy and water resources are drawing increasing attention in China as indispensable elements of economic development and social stability. Energy and water are interconnected in economic systems. Although the nexus between them has been widely studied, few insights can be acquired by the intermediate transmission pressures across supply chains. Combing betweenness-based method and multi-regional input-output (MRIO) analysis, we, in this study, identified critical transmission sectors and main driving factors resulting from the usage structure. In details, we found that Metallurgy (S14) in Shandong, Henan, Jiangxi, Anhui, Sichuan, Zhejiang, Hunan, and Jiangsu, Electricity and hot water production and supply (S22) in Beijing and Guizhou, and Nonmetal production (S13) in Henan are the most critical transmission sectors bearing energy-water nexus pressures, ranking at the top 100 in China's supply chain networks. Roughly, the usage structure was mainly dominated by fixed capital formation, urban household consumption and trade export, and therefore should be given priority to mitigate environmental pressures. Our study provides a novel perspective of sector-specific and province-typical policy recommendations for mitigating energy-water nexus pressures in China's supply chain networks.
能源和水资源作为经济发展和社会稳定不可或缺的要素在中国越来越受到关注。能源和水在经济系统中是相互关联的。尽管它们之间的关系已经得到了广泛的研究，但通过供应链中间传输压力获得的见解很少。本文将基于中心度的方法和多区域投入产出（MRIO）分析相结合，确定了由使用结构引起的关键传输部门和主要驱动因素。具体来说，我们发现山东、河南、江西、安徽、四川、浙江、湖南和江苏的冶金（S14）、北京和贵州的电力和热水生产供应（S22）以及河南的非金属生产（S13）是承载能源-水关系压力的最关键传输部门，在中国供应链网络中排名前 100 位。总的来说，使用结构主要由固定资本形成、城市家庭消费和贸易出口主导，因此应优先考虑减轻环境压力。我们的研究为中国供应链网络中缓解能源-水关系压力提供了一种部门特定和典型省份的政策建议的新视角。
