Abstract: This study inspected the relationship between international iron and steel industry transfer and innovation of iron and steel technology platform in a long time span. The study found the following new rules: the iron and steel smelting technology is under continual change which requires local industry support. Besides, the innovation center of steel technology is in traditional steel superpowers, and the innovation of revolutionary technology platform is usually implemented in emerging areas, which will promote industry formation and promotion in foreign lands and cause international transfer in iron and steel industry. In addition, the traditional technology cannot compete against the impact of new technology. Actually, China has become the center of iron and steel industry. Therefore, China needs to speed up iron and steel technology innovation and extend the life span of steel industry. Not only does innovation need to seek differentiation, but also it needs to form a complete set of technology and focuses on the development orientation in the transformation of technology platform when meeting the diversified market demand in order to achieve transformation and promotion of China’s iron and steel industry by technology innovation platform.

Key words: steel industry, technological platform change, industry transfer, industry center, industry life span
