基于网络视角"一带一路"农产品贸易格局演化分析
首发时间:2018-05-10
摘要:本文基于UNComtrade1992-2015年"一带一路"沿线65个国家农产品贸易数据,采取复杂网络分析方法,从无权网络和有权网络两个方面,选取节点数、密度、聚集系数等指标对其进行结构分析,并对网络的核心-边缘分布进行了探究,此外本文使用Walktrap算法对"一带一路"农产品网络进行了社团划分。结果表明:"一带一路"农产品贸易网络联系紧密,并且网络节点度的核密度表现出由"双峰分布"向"单峰分布"的变化趋势;呈现较明显的核心-边缘分布,且社团变迁明显。

From the perspective of network analysis "The Belt and Road" pattern based on the trade of agricultural products
Abstract:The 65 national agricultural products trade data of UNComtrade1992-2015 "The Belt and Road along take based on complex network analysis, from the unweighted network and has the right to two aspects of the Internet, select index node number, density, aggregation coefficient of analyzing its structure, and the core of the network edge distribution is explored, In addition, this paper uses Walktrap algorithm to The Belt and Road "network of agricultural products were divided societies. The results show that: "The Belt and Road" agricultural trade network closely, and node degree kernel density exhibited by the "Shuangfeng distribution" to "the trend of single peak distribution"; showing obvious core - edge distribution, and community changes obviously。
Keywords: International trade complex network The Belt and Road agricultural products trade community structure
