摘要:

水产品贸易是海洋经济的重要组成部分,是保证水产品有效供给、维护渔业产业链的重要措施。优化水产品贸易网络对保障中国粮食安全和扩展国际贸易具有重要意义。文章借助联合国商品贸易数据库,选取2000—2019年“21世纪海上丝绸之路”沿线国家水产品贸易数据,利用社会网络分析方法,测度“21世纪海上丝绸之路”沿线国家水产品贸易网络结构特征,进而分析沿线国家水产品贸易市场结构和产品结构。研究发现:1)2000—2019年“21世纪海上丝绸之路”沿线国家的水产品贸易变化可划分为2个阶段,其中第一阶段(2000—2008年)为平稳增长期,第二阶段(2009—2019年)为波动发展期。2)水产品贸易网络密度逐渐增大,空间集聚和网络凝聚力逐渐增强,网络的可达性不断提高,呈现小世界的特性。3)水产品贸易网络的核心—边缘结构较为稳定,核心国家的贸易联系紧密,贸易额占整体的一半以上,多边、双边贸易流存在差异,贸易网络的空间非均质性特征凸显;地理区位及距离对其组团有间接的影响,社团划分呈现层级性和地理临近组团的特点。4)水产品贸易网络的空间分异特性较为明显,重要节点国家主要集中在中国和东南亚国家,中间中心度高的国家和接近中心度排名靠前的国家具有趋同性,非洲东部及红海沿岸国家的网络中心性影响力较弱。5)在核心国家的水产品市场结构中,中国占据较大份额;国家间的关系变化引起市场结构发生调整;中国水产品进出口品种结构比较单一,进口和出口产品分别主要集中在冻鱼和水产品制品。

Abstract:

Aquatic products trade is an important part of the marine economy, and a key measure to ensure the effective supply of aquatic products and maintain the fishery industry chain. Optimizing the aquatic products trade network is greatly significant in guaranteeing China's food security and expanding international trade. With the help of the United Nations Commodity Trade Database, in this study, we select the aquatic products trade data of countries along the "21st Century Maritime Silk Road" from 2000 to 2019, measure the structural characteristics of the aquatic products trade network using the social network analysis method, and analyze the aquatic products trade market structure and product structure of countries located along the line. The results show the following. First, the changes in the aquatic products trade of countries along the "21st Century Maritime Silk Road" from 2000 to 2019 can be divided into two stages: the steady growth period from 2000 to 2008, and the fluctuating development period from 2009 to 2019. Second, the density of the aquatic products trade network is gradually increasing, spatial agglomeration and network cohesion are being gradually enhanced, and the accessibility of the network is continuously improving, which shows the characteristics of small cosmopolitan. Third, the core-periphery structure of the aquatic products trade network is stable, and the trade of the core countries is closely linked, accounting for more than half of the total trade volume. Geographical location and distance indirectly affect the group. The division of community shows the characteristics of hierarchy and geographical proximity. There are significant differences between multilateral and bilateral trade flows, and the heterogeneity of trade cyberspace is obvious. Fourth, the spatial differentiation characteristics of the aquatic products trade network are relatively obvious. The important node countries are mainly concentrated in China and Southeast Asia. Countries with high betweenness centrality and countries with high closeness centrality have convergence, and the network centrality influence of East Africa and the Red Sea coastal countries is weak. Fifth, China occupies a large share of the aquatic products market structure of the core countries. The change in the relationship among countries causes adjustments in the market structure. The import and export structure of aquatic products in China is relatively single. The imports consist mainly of frozen fish, while the exports consist mainly of processed aquatic products.
