东北亚石油贸易网络的结构特征与演进趋势

Structural Characteristics and Evolution Trends of Northeast Asian Petroleum Trade Network

刻画东北亚域内石油合作网络并进行深入的结构和特征分析对于中国制定并优化相关政策,进而更加主动地融入该能源合作网络具有重要意义。基于此,利用社会网络分析法构建了东北亚域内能源合作网络,从多个角度探究了网络结构特征,剖析国家间石油"流动"情况,探索东北亚域内石油资源分布和加工情况对贸易网络的影响,为中国主动融入并推进能源贸易网络演化提供有效参考。研究表明:国家之间经济依赖度与石油资源首位进出口对象国分布对网络密度皆有较大影响;东北亚域内在石油贸易上存在较为明显的两极分化;东北亚域内石油贸易联系越发紧密,贸易网络越发坚固,越有利于东北亚域内国家应对当前挑战与机遇。

Describing the dynamics of Northeast Asian petroleum trade network is of vital significance for China to formulate better policies, and thus to integrate into the energy cooperation network more actively. Based on this, social network analysis method was used to establish the energy cooperation network in Northeast Asia, and its characteristics were explored from multiple perspectives. Moreover, the “flow” of petroleum between countries was analyzed, and the impact of the distribution and processing of oil resources on the network was explored, which can provide effective reference for China to promote the evolution of the energy trade network. Studies showed that, the economic dependence between countries and the distribution of the first import and export target countries for petroleum resources had a greater impact on network density. There was obvious polarization in the oil trade in Northeast Asian. The closer the oil trade links in this region, the stronger the trade network, the more beneficial the countries in Northeast Asia were to meet current challenges and opportunities.
