水能联系（Water-energy nexus， WEN）是一个国际热点问题，而生产活动产生的直接联系效应越来越受到人们的关注。在此背景下，本研究首先采用多区域投入产出（MRIO）分析，考虑到基于生产的视角、基于中间点和基于消费的视角，对中国整个供应链的水和能源使用情况进行了全面分析。然后应用主成分分析（PCA）进一步针对中国30个省份的关键WEN部门。结果表明：(1)在大多数省份，生产活动造成的直接温升压力主要集中在几个传统资源密集型行业，尤其是S22（电力和蒸汽的生产和供应）和S14（金属的冶炼和压制）。(2)各省区温压力最大的输送行业为化工及化工产品制造业（S12），其次为S14。S22是几个省份的重点传播中心，福建和湖北的S7（纺织制造）和浙江和海南的S10（造纸和印刷）也应引起高度关注。(3)最终消费驱动的间接WEN压力均出现在建筑业。此外，S16（一般和特殊用途机械的制造）和S17（运输设备的制造）是一些省另外两个主要的以消费为基础的WEN部门。总体而言，在全国范围内，江苏省面临的WEN压力相对较大，湖北S12是唯一一个从三个角度来看都面临较大WEN压力的行业。研究结果对中国区域可持续发展具有借鉴意义。
Water-energy nexus (WEN) is an international hot-spot issue, while more attentions have been paid to the direct nexus effect resulting from production activities. In this context, this study firstly used the multiregional input-output (MRIO) analysis to offer a full spectrum of water and energy usage throughout the whole supply chain in China, considering production-based perspective and betweenness-based and consumption-based perspectives. And then the principal components analysis (PCA) was applied to further target the critical WEN sectors in Chinese's 30 provinces. The results show that: (1) For most of these provinces, the direct WEN pressure caused by production activities can be found in several traditional resource-intensive sectors, especially in S22 (Production and supply of electric power and steam) and S14 (Smelting and pressing of metals). (2) The most critical transmission sectors with WEN pressure was S12 (Manufacture of chemicals and chemical products), followed by S14 in most of these province. S22 was the key transmission center in several provinces, and S7 (Manufacture of textile) inFujianandHubeiand S10 (Papermaking and printing) inZhejiangandHainanshould also be highly-concerned. (3) For all of these provinces, the indirect WEN pressure driven by final consumption appeared in S24 (Construction industry). In addition, S16 (Manufacture of general and special-purpose machinery) and S17 (Manufacture of Transport equipment) were the other two key consumption-based WEN sectors in some provinces. Overall, the WEN pressures inJiangsuwere relatively great in China, and S12 inHubeiwas the only sector facing great WEN pressure from all three perspectives. Our results can draw implications for regional sustainable development in China.
