Abstract:As the critical point of regional industrial development, the iron and steel industry is also a significant battlefield for regional coordinated development. This paper used a bottom-up method to establish an energy saving and CO2 emission model of iron and steel industry in key regions to analyze the impact of regional characteristics on energy saving and emission reduction. Taking 2015 as the base year and based on the prediction results of crude steel output, the model set four scenarios about the popularization of energy saving and emission reduction technology and adjustment of production structure to analyze the energy consumption and CO2 emission of iron and steel industry in the key regional of China from 2015 to 2030. The results showed that reducing steel output was the fundamental measure for energy saving and CO2 emission reduction in the iron and steel industry. As the regional crude steel output entering the peak area, the contribution for energy conservation of technology popularization factor would continue to decrease, while the contribution for energy conservation and CO2 emission reduction of production structure adjustment would gradually increase, which becoming the key source of dividend for energy conservation and CO2 emission reduction of iron and steel industry in key regions. Meanwhile, the market demand was the regional characteristic that had the greatest impact on the development of iron and steel industry in key regions. Furthermore, the influence of economic and industrial policies and environmental protection requirements on the development of iron and steel industry was gradually increasing. In the future, the development of iron and steel industry in key regions would still be market-oriented, and new-added capacity would be laid out in regions with abundant water resources and convenient transportation.
