美日铸件市场结构变化和大量的过剩生产能力思考

Changes of Market Structure & Great Number of Overcapacities in Japan & the U.S.A

钢坯连铸技术和乘用汽车轻量化 节能化两项技术进步 ,先后为日本和美国节省数百万吨的铸件年需求量。然而 ,日本凭借领先的巨大优势 ,在 80年代初钢铁、汽车等一系列传统工业产量超过美国 ,实现震惊世界的“日美易位”。美国为落后付出的代价是 ,经历了传统工业的大动荡 ,大改组 ,已经在日本和美国发生的过 ,迟早也会在世界其他地方再现。市场结构变化造成年产数千万吨铸件的过剩生产能力。对于国外发生的重大变革 ,我们应该予以充分思考。

Two progresses by the technology of continuous casting of steel & a lighter and more fuel-efficient passenger car led Japan & the U.S. decreased the demand of castings sooner or later by millions of tons. Meanwhile, since the early 1980s, Japan has preponderated over the U.S. in production of iron and steel making, and automobiles .At the same time, the U.S. had suffered from the shaking up of its traditional industrial culture, and had to pay a fully attention to the changes of market structureovercapacities by more than 40 million tons/a worldwide.
