As the world's largest energy consumer and carbon dioxide emitter, China faces enormous challenges in resource utilization, energy consumption, and environmental pollution. The steel industry is an important pillar industry in modern economic development, and its development level directly affects the pace of China's modernization process. At the same time, the steel industry is also one of the most energy-consuming and environmentally damaging industries, so it is a key area for implementing energy conservation and emission reduction. Researching how to improve the economic feasibility of the steel industry with lower resource and environmental impacts plays an important role in promoting green growth and development of this industry, and even the entire macro economy.
