Comparative Analysis of Asian Main Iron and Steel Countries' Total Factor Energy Efficiency

This article evaluates the total factor energy efficiency, energy conservation potential and emission reduction potential of the typical enterprises in the main iron and steel-producing countries such as China, India, Japan and Korea by applying the SBM-desirable DEA model and the SBM-undesirable DEA model. The findings are beneficial for understanding the development status of the main Asian iron and steel-producing countries. The empirical results indicate that the Chinese iron and steel enterprises in the sample made great progress in terms of the total factor energy efficiency. Korea's POSCO and Japan's JFE Group and Nippon Steel enterprise performed the best in terms of energy efficiency, energy conservation and emission reduction. The total factor energy efficiency value of India's Tata Steel is comparatively well. It has completed Jamshedpur Works' brownfield expansion project, which help it add eco-efficient products to its portfolio while using fewer natural resources, less energy and less water per tonne of steel produced.
