钢铁行业具有典型的规模经济特征,钢铁工业生产工艺决定了其大型化和规模化的发展方向,20世纪后半叶,淮钢冶炼钢和铁的经济规模都在百万吨以上,现代化的线材生产的规模在40万吨,热轧板材生产线的规模在300万吨。钢铁行业的规模经济特征,决定了钢企的用工人数众多,且工种繁杂,怎样将难度越来越 The iron and steel industry has the typical characteristics of economies of scale. The steel industry’s production technology determines its direction of large-scale and large-scale development. In the second half of the 20th century, the economic scale of Huaigang’s smelting of steel and iron was over 1 million tons. Modern wire The scale of production is 400,000 tons, the scale of the hot rolled sheet production line is 3 million tons. The scale of the iron and steel industry, economic characteristics, determines the number of large steel workers, and the type of complex, how to make the more difficult
