Abstract:

Bauxite, the raw material for aluminum production, is a bulk commodity in international trade. China is the world's largest importer of bauxite. It is of great significance for China to adjust its production capacity structure by analyzing the changes in the bauxite flow pattern and its evolution causes since this century. In this paper, the concept of resource field is introduced, the gravity model of bauxite resource field is constructed, and the cause of its change is revealed. The results are as follows: geographically, the flow of bauxite resources in the world is a process of moving from the southern hemisphere to the northern hemisphere; the potential of resource field determines the change of bauxite resource flow trace; the Strait of Malacca is the most important maritime channel from Guinea to China, accounting for 44% of China's imports of bauxite; the supply capacity of the world's bauxite exporting countries and the strong production demand of the importing countries are the basic driving forces to promote the flow of bauxite resources. However, transportation cost and increase of bauxite prices are the basic obstacles to its flow. This study reveals the flow pattern of bauxite resources in the world in recent years and its evolution causes, which has reference significance for the relevant departments of China to formulate relevant policies scientifically.

摘要:

铝土矿是国际贸易中的大宗货物,中国是世界最大的进口国之一。探讨21世纪以来世界铝土矿流动格局的变化,分析其演变成因,对于中国调整产能结构具有重要借鉴意义。本文引入资源场概念,构建了铝土矿资源场引力模型,揭示了其变化成因。结果表明:世界铝土矿资源的流动是自南半球起至北半球横跨大洲的海上搬迁过程;资源场的位势决定了铝土矿资源流动迹线的变化;马六甲海峡是几内亚至中国最重要的海上通道,其运量占中国铝土矿进口量的44%;世界铝土矿输出国充足的供给能力和输入国旺盛的生产需求是推动铝土矿资源流动的基本驱动力,运输成本和铝土矿价格是其流动的基本阻力。本研究揭示了近年来世界铝土矿资源的流动格局及其演变成因,对于中国有关部门制定相关政策具有借鉴意义。
