Large-scaled interregional trade is based upon massive exchanges of natural resources, leading to more environmental emissions and economic imbalance. China is the largest trade country in the world and has to face such challenges since different Chinese provinces are in different development stages with different resource endowments. By using the latest multi-regional input-output (MRIO) tables and exergy accounting, this study aims to investigate natural resources and added values embodied in interregional trade in China for years of 2012, 2015, and 2017. Regional environmental inequality (REI) index and logarithmic mean Divisia index (LMDI) were applied to measure the imbalance states and uncover corresponding driving factors. Results show that the total trade volumes in the middle Yellow River and eastern coastal regions were generally higher than those in other regions, together accounting for 41.50 ~ 41.78% of the total trade volume during the study period. The major flows of embodied natural resources shifted from the middle Yellow River region to western coastal, eastern coastal, and southern coastal regions. The northern coastal and eastern coastal regions were the major exporters of embodied added value. Less developed regions had higher REI values, indicating more environmental and economic losses than developed regions. Natural resources intensity was the major impact factor on the trade imbalances in most provinces. This study provides valuable insights for alleviating trade imbalance and promoting sustainable natural resources management based on cross-regional collaboration.
大规模的区域间贸易是建立在大规模的自然资源交流基础上的，这导致了更多的环境排放和经济不平衡。中国是世界上最大的贸易国，必须面对这样的挑战，因为中国不同的省份处于不同的发展阶段，拥有不同的资源禀赋。本研究利用最新的多区域投入产出（MRIO）表和火用分析，旨在调查中国 2012、2015 和 2017 年区域间贸易中所包含的自然资源和附加值。采用区域环境不平等（REI）指数和对数平均迪维西亚指数（LMDI）来衡量不平衡状态，并揭示相应的驱动因素。结果表明，黄河中游和东部沿海地区的总贸易量普遍较高，占研究期间总贸易量的 41.50%至 41.78%。所包含的自然资源主要流向从黄河中游地区转移到西部沿海、东部沿海和南部沿海地区。北部沿海和东部沿海地区是所包含附加值的主要出口地区。欠发达地区的 REI 值较高，表明其环境和经济损失比发达地区更大。自然资源强度是大多数省份贸易不平衡的主要影响因素。本研究为缓解贸易不平衡和促进基于跨区域合作的可持续自然资源管理提供了有价值的见解。
