摘要
在全球水资源短缺与区域经济发展不平衡的背景下,中国省际虚拟水流动中“资源输出地承担环境成本、经济输入地获取发展红利”的非公平现象显著。基于2017年中国多区域投入产出表,构建“虚拟水强度-增加值率”关联模型,结合象限分析与公平性指数,量化31个省份19个行业的虚拟水流动的公平性失衡问题。研究发现:东部沿海形成“虚拟水输入-高附加值输出”的高效模式,中西部资源型产业面临“高耗水-低回报”困境,新疆农业等案例证明节水技术与高附加值产业可破解公平性矛盾。本研究可作为跨区域生态补偿与产业结构优化的量化依据。
Against the backdrop of global water scarcity and unbalanced regional economic development,the inequity in China's interprovin⁃cial virtual water flows,where resources⁃exporting regions bear environmental costs while economic⁃importing regions gain development divi⁃dends,is remarkable.This study,based on the 2017 Chinese multi⁃regional input⁃output table,constructed a“virtual water intensity⁃value added rate”correlation model,combining quadrant analysis and an equity index to quantify the virtual water economic efficiency of 19 indus⁃tries in 31 provinces.The research reveals that the eastern coastal areas have formed an efficient model of“virtual water input⁃high value⁃added output”,while resources⁃based industries in the central and western regions face the dilemma of“high water consumption⁃low return”.Cases like Xinjiang's agriculture demonstrate that water⁃saving technologies and high⁃value⁃added industries can resolve equity contradictions.This study provides a quantitative basis for cross⁃regional ecological compensation and industrial structure optimization.
