利用社会网络分析方法构建2017—2019年全球竹产品贸易网络,从整体网络特征、网络中心度、块模型和主要贸易国家等4个方面研究全球竹产品贸易网络特征。结果表明:5种竹产品贸易网络总体关系均较为稀疏,但竹制品贸易网络的连通性、扩散性、稳定性及集聚程度相对较强;网络节点度数中心度的“核心-边缘”特征明显,与进口网络相比,竹产品出口市场集中度更高。5种竹产品贸易网络均可划分为4个板块,且板块1均为内外贸易关系较为紧密的双向溢出板块。竹产品贸易大国网络呈现以中国为核心的星形分布,贸易关系主要发生在亚洲、美洲和欧洲之间。以中国为主的亚太“贸易圈”和以美国为主的欧美“贸易圈”是当前全球竹产品贸易网络中最主要的2大社群。

The paper built the global bamboo products trade networks from 2017 to 2019 according to social network analysis methods,and studied the trade network from four aspects:overall network characte-ristics,network centrality,blocks,and main trade countries. The results showed that the overall densities of the five networks were relatively sparse,while the connectivity,diffusion,stability and concentration of the bamboo products trade network were relatively strong. The "core-periphery" feature of the degree centrality of the network nodes was obvious. Compared with the import network,the bamboo products export market was more concentrated. Each of the five networks can be divided into four blocks,and block 1 was always a two-way spillover block with close internal and external trade relations. The networks of major bamboo products trading countries presented a star-shaped distribution with China as the core,and trade relations mainly occurred among Asia,America and Europe. The Asia-Pacific "trade circle" with China as the core and the European and American "trade circle" with the United States as the core were the two most important communities in the current global bamboo products trade network.
