| 英文摘要 | China faces significant challenges in water resource management due to the spatial mismatch between water availability and demand, intensified by rapid urbanization and industrialization. Urban agglomerations-key engines of economic growth-are particularly vulnerable to water stress. While virtual water flow (VWF) has been extensively acknowledged as a mechanism for reallocating water resources through trade, the impact of domestic trade in alleviating regional water scarcity is not yet fully comprehended, especially across interconnected urban agglomerations. We systematically assess the VWF patterns among China's urban agglomerations using the multi-regional input-output (MRIO) model. To quantify the contribution of trade to water scarcity mitigation, we develop a novel indicator: virtual water trade compensation index (VWTCI). Results show that urban agglomerations collectively saw a decline in blue water footprint from 394.67 to 380.11 billion m3 during 2012-2017, corresponding to 81.40 % and 79.42 % of the national total, respectively. Domestic trade plays a progressively important role in redistributing water resources, promoting interregional synergy. However, its regulatory effect is heterogeneous: trade has expanded the extent and intensity of its role in alleviating water scarcity across urban agglomerations, it has also significantly exacerbated water scarcity risks in some regions. The driving forces behind water footprint changes have shifted from technological progress to a dual mechanism of structural transformation and demand-side expansion. This study provides critical insights into the potential of domestic trade as a strategic instrument for reallocating water resources and improving sustainable water use in China's urban agglomerations. |
