ZHU Tan-wen; ABULA Bu-wa-jian

Based on the world vegetable oilseeds trade data, the topology, overall structural characteristics, individual centrality and community layout evolution of the global vegetable oilseeds trade network from 2003 to 2021 were studied by using social network analysis methods. The results reveal that: 1) with the passage of time, the global trade volume of vegetable oilseeds continues to grow, the formed trade network is more closely interconnected, showing a trend of centralization, and the characteristics of "small world" and scale-free nature become more prominent; 2) The distribution pattern of the community of the global vegetable oilseeds trade network has been deeply adjusted, and the community structure is closer and the geographical distance is more likely to form associations; 3) Countries such as China and India in Asia, France, Germany and the Netherlands in Europe, Brazil and Argentina in South America, the United States and Canada in North America, and Australia in Oceania hold high core positions in the trade of vegetable oilseeds. Additionally, Turkey, Mexico and Paraguay also hold pivotal position in the international trade of vegetable oilseeds; 4) China's dependence on vegetable oilseeds imports has decreased significantly, but it is still mainly concentrated in Brazil and the United States. In this regard, it is suggested that China should promote diversified development of vegetable oilseeds import products and markets, expand export income generation, and make full use of the international trade platform mechanism to promote the high-quality development of China's vegetable oilseeds trade.
