摘　　要：近年来,粮食国际贸易趋势愈发明显。基于2010—2019年粮食国际贸易数据构建粮食国际贸易网络,利用社会网络分析方法探究中国粮食国际贸易格局及社团分布。研究发现,世界粮食贸易具有较强的关联性,粮食贸易网络已经成为不可分割的有机体;网络密度与互惠性指数的基数较低,但呈现出小幅上升趋势,中国在优化粮食资源配置效率方面具有很大的提升空间;粮食国际贸易网络具有明显的中心性特点,各国粮食贸易关系差异变化微弱,但粮食贸易联系具有愈发紧密的趋势,中国在粮食国际贸易中的地位不断巩固,承担了粮食贸易网络中更多的“桥梁”功能;粮食国际贸易国家社团分布呈现一定的地域特点,同时又突破地域限制。通过对中国粮食国际贸易格局及社团分布的研究,可以为粮食国际贸易的顺利开展提出合理的决策建议,同时,对确保中国粮食安全具有深远的意义。In recent years,the trend of grain international trade is more and more obvious.Based on the grain international trade data from 2010 to 2019,this paper constructs the grain international trade network,and uses the social network analysis method to explore the pattern and community distribution of China’s grain international trade.The results show that the world food trade has a strong correlation,and the food trade network has become an inseparable component;the base of network density and reciprocity index is low,but it shows a small upward trend,and China has a lot of room for improvement of the efficiency of optimizing the allocation of food resources.The international grain trade network has obvious central characteristics,and the differences of grain trade relations among different countries are weak,but the grain trade relations are much closer.China’s position in the international grain trade has been consolidated,and it has undertaken more“bridge”functions in the grain trade network.The distribution of international grain trade associations presents certain regional characteristics,but at the same time,it is also prominent to break regional restrictions.The results of this study have far-reaching significance for promoting the smooth development of international grain trade and ensuring China’s food security.
