基于复杂网络的国际农产品贸易分析

本文基于2001~2016年国际农产品贸易数据,采用复杂网络分析方法,评估各国在贸易网络中的地位,并借助QAP相关分析(Quadratic Assignment Procedure)探究国际农产品贸易网络结构的影响因素。研究结果表明:2001~2016年综合中心性排名前10的国家整体格局未发生剧烈变化,且大多为发达国家,美国、中国、德国位居前列;国家间的GDP、人口、国土面积、农业用地面积和外商直接投资的差异与全球农产品贸易显著正相关,而距离、收入差距对其有负向影响。

Analysis of International Agricultural Products Trade Based on Complex Network

Based on the data of agricultural products trade from 2001 to 2016,this paper uses the complex network analysis method to assess the status of countries in the trade network and explores influencing factors of agricultural products trade network structure by QAP correlation analysis.The results show that:there has been no dramatic change in the overall pattern of the top 10 countries in comprehensive centrality ranking from 2001 to 2016,and most of them are developed countries;The United States,China and Germany are in the forefront.The differences of GDP,population,land area,agricultural land area and foreign direct investment among countries are significantly positively correlated with global agricultural products trade,while distance and income gap have a negative impact.
