强调了对钢铁行业能耗、物耗和排放进行深入、透彻研究的重要性，说明了本研究工作的指导思想、思维方式和理论基础，构思了一张钢铁行业宏观调控网络图，推导了一组多比值计算式；它们都是进行精准、有效的宏观调控所必备的理论工具。回顾过去，确定了我国钢铁行业能耗高、物耗高、排放高的主要原因；展望未来，提出了今后调控工作的原则、方向和长远目标。本文初次阐明了钢铁行业宏观调控的理论和方法。

The importance of carrying out deep and thorough study on energy consumption， material consumption and waste emission of steel industry was emphasized. The guideline， way of thinking and theoretical base of the study were illustrated. A network diagram for macro-control on steel industry was conceived， and a group of multi-ratio formulas was derived； both of them are necessary theoretical tools for precise and effective macro-control on steel industry. Looking back， the main reasons for extra huge amount of energy consumption， material consumption and waste emission of China’s steel industry were identified. Looking forward， the principle， direction， and long-term target of the macro-control in the future were put forward. In a word， the theory and methodology of the macro-control on steel industry were initially formulated.
