北极航线经济圈贸易网络的结构洞分析

Analysis on the economic circle trade work of Arctic shipping routes based on structural holes theory

北极航线的开通将会对其经过地区的经济贸易产生巨大影响,该文利用结构洞理论的中介中心性指标对北极航线经济圈的贸易网络节点进行静态比较分析.研究结论:1)随着中国经济的发展,中国已成为北极航线经济圈贸易网络中最重要的节点之一.2)中、韩、日、美、加五国与北极航线经济圈国家的贸易联系最为密切,在贸易网络中占有重要地位.3)北极航线经济圈贸易主要来自于中国、日本、韩国、美国、俄罗斯等国,这些国家是北极航线经济圈贸易的主要参与者.同时,这些国家也是中国在北极航线经济圈主要的贸易伙伴.4)北极航线的开通,缩短了东亚、欧洲、美洲的距离,将会使北极航线经济圈贸易联系更加紧密.其中,中国、美国、日本、韩国等国由于拥有丰富的结构洞和活跃的贸易联系,优势更大.

The opening of the Arctic routes would have grievous impact on the trade bus- iness of the areas the Arctic routes affected. The characters of the node in the economic circle trade network of Arctic routes are analyzed comparatively by the betweenness cen- trality from structural holes theory in this paper. The finding indicates that. 1） with the rapid economic development, China has become one of the most essential nodes; 2） there exists particularly close trade connection among countries in the Arctic route eco- nomic circle including China, South Korea, Japan, the United States and Canada,which keeps playing an important role in the trade network; 3） the trade of the Arctic route e- conomic circle are mainly formed by China and countries such as Japan, Korea, Ameri- ca, Russia, and thus the above countries become the key participants in the economic circle of Arctic route. In addition, the latter countries are also major trading partners for China; 4） the trade links for economic circle of Arctic route become more close due to shortening of the transportation distance among East Asia, Europe and America with the open- ing of the Arctic route. Whereby, China, the United States, Japan and South Korea will have greater advantage because of the rich structural holes and active trade links.
