| 摘 要： | 依据中美原油进口源地数据,运用网络分析法,比较了中美原油进口贸易空间结构的演化轨迹与特征。研究表明,相同的认知活动使两国的原油进口策略取向变得一致。1993年后,美中原油进口来源国数量有着几乎相同的增长趋势;但美国原油进口权重基本趋于平稳,中国原油进口权重基本处于上升通道中,同时中美贸易联系不仅存在强度上的差异,分区域的强度次序也存在重大差异;美国原油进口空间格局的权重熵经历了由高到低的演变,权重熵的比较揭示出1993年之后中国原油进口系统有序性要低于美国。以上结果表明追求多元化不应以均质化为目标,不同的主体要依据各自所面临的客观环境选择适合自己的区域合作伙伴,才能更好的落实多元化进口策略,切实解决可能面临的石油供给危机。

| Abstract: | With the yearly increase of crude oil import of China, the safety issues of import have become more prominent. The strategy of diversification of import channels has been considered the primary solution to overcoming safety issues. However, the adoption of diversification strategy premises a thorough analysis and understanding of the importing strategy of other countries in advance. This paper employed the complex network method and evaluated the degree, weight, and entropy of China versus United States in the network of crude oil import and revealed the evolving mechanism of the degree, weight, and standard entropy. Analysis of a regional comparison was also carried out to highlight the difference of crude oil sources between China and United States. Conclusions were drawn as follows. First,identical cognition causes consistent policy making. Diversifying strategy has been a common option to both China and United States. Since 1993, the patterns of crude oil import of both China and United States have demonstrated similar tendency of change in the quantity of trade partners. Second,since 1993, China and United States have been quite distinct in the weighted pattern of trading business. The weight of crude oil import network of United States is generally stable, while that of China presents a trend of rapid growth. In the mean time, the weight of United States is remarkably more than that of China. Furthermore, in the aspect of sub-region's weight, the crude oil import of United States is more dependent on relatively safer countries in North America, e.g. Canada and Mexico, rather than unrest Middle East.Third,The weighted entropy of the crude oil import network of United States experienced a transition from large to small, while China generally maintained a larger value. Comparison of these two entropy parameters from China and United States indicates that the level of maintaining orderliness in the crude oil import network is much higher in United States than that in China. In addition it reminds that diversification does not necessarily mean homogenization. The distribution of a country's trading partnership depends on its individual and specific trading environment, which is virtually the essential to carry out the strategy of diversification. |
