As a special branch of global trade,the trade of agricultural products has an important impact on food security and the environment.In this paper,we studied international trade network of agricultural products from 2000 to 2016 as a whole and in part.We explored the overall characteristics of the network,analyzed the evolution of communities and identified core countries of the communities.The results show that the structure of the trade network became increasingly complex and the trade relations became closer over time.There were four major communities in the network,whose primary core countries were Germany,the United States,Brazil,and China.Since 2007,the community represented by China has disappeared,and the community pattern of the network has been in a three-pillar state and basically stable.We discuss the actual roles of certain trading countries,the formation of communities and the impact of economic events on agricultural products trade.This paper reveals the underlying patterns of the agricultural products trade and provides a way to track its evolution over time.
