一、八十年代欧洲和西方世界的原铝生产与消费原铝消费量与整个工业发展有不可分割的关系。因此,西方世界原铝消费量的增加与不同经济地区国民生产总值(GNP)的增长密切相关(可以用弹性指数表示)。在最近30年中,弹性指数非常接近2(一些国家的平均值为1.8)。可以预计,尔后十年,西方世界国民生产总值的增长不仅会减速, Primary and Secondary Aluminum Production and Consumption in Europe and the Western World in the 1980s and 1980s The consumption of primary aluminum is inextricably linked to the development of the entire industry. Therefore, the increase of primary aluminum consumption in the western world is closely related to the growth of GNP in different economic regions (as can be shown by the elasticity index). In the last 30 years, the elasticity index is very close to 2 (in some countries the average is 1.8). It can be predicted that the growth of gross national product in the western world will not only slow down in the next decade,
