摘要

摘要本文研究了南部非洲发展共同体(SADC)国家间谷物流中虚拟水的区域内双边贸易。采用重力模型来检验年度双边贸易是否取决于水禀赋的差异，但也包括影响贸易的社会经济和政治决定因素。有证据表明，一个国家的水资源丰富程度会影响依赖水的产品的贸易。因此，一个国家缺水的不利影响可以通过鼓励在水丰富的地方出口用水密集的谷类作物和在缺水的地方进口来改善。我们感谢国际水管理研究所、IFPRI、akademiy2063、比尔和梅林达·盖茨基金会以及美国国际开发署对ReSAKSS项目的支持，该项目的活动之一促成了本文的发表。本文仅代表作者的观点，不代表上述机构的观点。披露声明作者未报告潜在的利益冲突。数据可用性本分析中使用的数据来自联合国商品贸易统计(https://comtrade.un.org/)、联合国粮农组织aquastat数据(https://www.fao.org/aquastat/en/)、世界银行发展指标(http://datatopics.worldbank.org/world-development-indicators/)和联合国粮农组织生产数据库(https://www.fao.org/faostat/en/#data/QCL).Notes1)。南共体成员国包括安哥拉、博茨瓦纳、科摩罗、刚果民主共和国、莱索托、马拉维、马达加斯加、毛里求斯、莫桑比克、纳米比亚、塞舌尔、南非、斯瓦蒂尼、坦桑尼亚、赞比亚和津巴布韦。在分析中，只有科摩罗、刚果民主共和国、塞舌尔和安哥拉被排除在外。本研究与任何特定基金无关。

Does bilateral trade in cereals within SADC reflect virtual trade in water between countries with different water endowments?

ABSTRACTThis paper examines intraregional bilateral trade in virtual water embedded in cereal flows between the Southern Africa Development Community (SADC) states. A gravity model is employed to examine whether annual bilateral trade depends on differences in water endowments, but also includes socio-economic and political determinants that affect trade. There is evidence that the abundance of water resources in a country influences trade for a product that is water dependent. Thus, the adverse effect of water scarcity in a country may be ameliorated by encouraging exports of water-intensive cereal crops where water is in abundance and imported where water is scarce.KEYWORDS: bilateral trade in cerealswater endowmentsvirtual water tradegravity modelSouthern Africa Development Community (SADC) AcknowledgementsWe are grateful to the International Water Management Institute, the IFPRI, AKADEMIYA2063, the Bill and Melinda Gates Foundation, and the United States Agency for International Development for their support for the ReSAKSS programme, one of whose activities led to this paper.

期刊介绍： Water International is the official journal of the International Water Resources Association (IWRA), founded in 1972 to serve as an international gateway to the people, ideas and networks that are critical to the sustainable management of water resources around the world. Water International''s articles, state-of-the-art reviews, technical notes and other matter are policy-relevant and aimed at communicating in-depth knowledge to a multidisciplinary and international community. Water International publishes both individual contributions and thematic special issues and sections on cutting edge issues. All individual manuscript submissions are subject to initial appraisal and peer review by the Deputy Editor in Chief and the Associate Editors, and, if found suitable for further consideration, to peer review by at least one independent, anonymous expert referee. All external peer review is double blind. Thematic issues and sections are handled under comparable procedures by guest editors under the oversight of the Editor in Chief.
