This paper evaluates the environmental performance of iron and steel enterprises by collecting the energy consumption, environmental emissions and financial data. The analysis of total factor productivity（TFP）shows that Maanshan iron and Steel Company's lack of enterprise management leads to low comprehensive technical efficiency, which indicates that the enterprise should avoid blind expansion, and focus on improving their scale economy level. The lack of technological innovation issues in Shandong Iron and Steel Company and Taigang Company's low Malmquist index. It is indicated that the two companies should put emphasis on energy-saving and cost-reducing. The results of efficiency value analysis show that there are obvious discrepancies among the sample enterprises. Like Hebei Iron and Steel Company, Maanshan Iron and Steel Company and Wuhan Iron and Steel Company, clean water depletion, energy consumption and sulfur dioxide emissions are the weak points of environmental performance management. Without control it may cause more serious impact on the social environment. Based on the evaluation and analysis of the environmental performance of these enterprises, these iron and steel enterprises should conscientiously improve the environmental performance by strengthening the efficiency of resource recycling, reducing the discharge of the three waste, and actively fulfilling the obligation of information disclosure.
