摘　　要：柑橘在世界水果业占有举足轻重的地位。本文运用2000—2020年世界各国的柑橘贸易数据,采用社会网络分析方法,利用Gephi可视化软件,构建了世界柑橘贸易网络,分析了近20年来世界柑橘贸易网络格局的整体演变特征和其中个别国家的属性变化。结果表明:2000年以来,世界柑橘贸易网络规模不断扩大,网络密度不断提高。荷兰和西班牙分别在无权和加权柑橘贸易网络中处于核心地位。多年来中国在贸易网络中的地位显著提升,与其他核心国家之间的差距持续缩小。此外,研究还发现,2020年新冠肺炎疫情对世界柑橘贸易网络产生了明显的冲击。最后,根据柑橘贸易网络的特点和中国在全球柑橘贸易网络中的地位变化,本文对中国柑橘产业和贸易发展提出了建议。Citrus occupies a pivotal position in the world fruit industry.Using the citrus trade data of countries around the world from 2000 to 2020,this paper adopts the social network analysis method,and uses the Gephi visualization software to construct the world citrus trade network,and then analyzes the evolution characteristics of the world citrus trade network and the attribute changes of Individual countries in the past 20 years.The results show that since 2000,the scale of the world citrus trade network has been expanding and the network density has been increasing.The Netherlands and Spain are at the heart of the unweighted and weighted citrus trade networks,respectively.Over the years,China’s position in the trade network has increased significantly,and the gap with other core countries has continued to narrow.In addition,the study also found that the COVID-19 in 2020 had a significant impact on the world citrus trade network.According to the characteristics of the citrus trade network and the change of China’s position in the global citrus trade,suggestions are made for the China’s citrus industry and trade.
