- 摘要:
- 基于复杂网络理论,选取2006~2014年国际LNG贸易量作样本数据,构建以34个国家或地区为节点、LNG贸易流动为边、贸易量为权重的全球LNG市场供需复杂网络模型。通过中心性度析,研究了各国家或地区在目前世界LNG供需格局中的地位及形成原因；通过强度和强度分布分析,研究了各国家或地区LNG贸易强度关系和贸易量的动态演变过程；通过权重熵分析,研究了LNG贸易空间结构的均质化程度。最后,基于以上分析,对中国LNG进口战略提出了建议。
Based on the theory of complex network, the global LNG trade volume from 2006 to 2014 was selected as sample data to build a complex network model of the global LNG market was constructed, including 34 countries as nodes and LNG trade flows as edge and trade volume as weight. Through centrality analysis, the status of various countries and areas in the LNG supply and demand structure and causes of their status in the LNG market were analyzed. By analyzing the strength and the strength distribution, the relationship between the intensity of LNG trade in these countries and regions, and the dynamic evolution process of the trade were discussed. Furthermore, by weighted entropy analysis, the degrees of homogenization of the spatial structures of LNG trades were analyzed. Finally, suggestions have been made for China's LNG importing strategy based on the above analysis.
