“一带一路”沿线国家粮食虚拟水贸易网络研究

“一带一路”沿线国家是世界粮食重要产区，有效利用虚拟水贸易战略，有利于缓解沿线国家的粮食困境，实现水资源的高效配置。论文基于2010—2016年的生产和气候数据，测算了沿线65个国家7种粮食的单位虚拟水含量，并结合相应粮食的贸易数据，构建虚拟水贸易网络模型。研究发现：该贸易网络具有小世界特性，出现逆全球化征兆；俄罗斯、乌克兰等是该贸易网络中主要的粮食虚拟水净出口国家，埃及、伊朗等是主要的粮食虚拟水净进口国家；中国保持着较高的中心性，其粮食虚拟水贸易规模持续扩大，在该网络中起着重要的桥梁作用。研究结果为改善“一带一路”沿线国家的农产品生产与贸易结构、合理利用水资源提供了可视化依据。

PROVISION-VIRTUALIZED WATER TRADING NETWORK ALONG “THE BELT AND ROAD”

Nations along “the Belt and Road” are important provision production areas. Effective use of virtualized water trading strategy helps mitigate the provision dilemma and realize the efficient allocation of water resource. This paper, based on production and climate data 2010 to 2016, estimates their unit virtualized water content of seven provisions in 65 nations along “the Belt and Road”, and sets up a virtualized water trading network model based on provision and trading data, which show a feature of small world of anti-globalization. Russia and Ukraine are net provision-virtualized water exporters, while Egypt and Iran are net importers. China remains the balance with expanding provision-virtualized water trading size, playing a role of bridge in the network. This paper presents a virtualized basis for improving their agricultural production and trading structure and utilizing water resource in the nations along “the Belt and Road”.
