Energy Efficiency Evaluation Of China’s Iron And Steel Enterprises Based On Entropy Weight-Cloud Model

The booming development of steel companies has led to a market situation of oversupply,which has affected the redevelopment of steel companies,and problems such as shortage of resources and pollutants have frequently appeared.The iron and steel industry is a key industry of China’s industrial system and a pillar industry for China’s economic development.However,the energy consumption and pollution problems of the steel industry cannot be ignored.The energy utilization level of the steel industry has a very significant impact on the local GDP energy consumption.Therefore,the analysis and research on the energy efficiency evaluation of China’s steel industry can not only be better.Understand the current situation of energy utilization in China’s steel industry,and develop corresponding improvement measures to help steel enterprises achieve the goal of green production of energy conservation and emission reduction,and achieve sustainable development of steel enterprises.Based on this theoretical analysis,the paper analyzes the energy utilization efficiency of China’s iron and steel enterprises from the theoretical and empirical analysis,analyzes the relevant literature through content analysis.The first chapter briefly introduces the background of the topic and the meaning of the topic.After that,it introduces the main research contents and methods of the thesis,analyzes the research status of relevant content at home and abroad,and explores the characteristics of energy consumption and the existing problems.The second chapter mainly introduces the basic concepts of energy efficiency related content,and studies and analyzes the current status of energy efficiency in China’s steel enterprises.The third chapter finds and analyzes relevant literature through content analysis method,and combines the research and analysis results.Since steel enterprises are high-energy enterprises,there are many projects affecting energy efficiency.Therefore,this dissertation summarizes the five aspects of economy,technology,resources,environment and society,and obtains the influencing factors of energy efficiency of iron and steel enterprises.After that,it is selected through the analysis of membership degree and correlation analysis to determine the evaluation index system of iron and steel enterprises.The fourth chapter mainly constructs the energy efficiency evaluation model of iron and steel enterprises.On the basis of analyzing the principle and ideas of the cloud model evaluation method,the index system involved in the energy efficiency analysis of China’s steel enterprises is clarified,and the weight of the indicators is determined by the entropy method.An energy efficiency evaluation model for steel companies based on the entropy-cloud model.The fifth chapter conducts empirical analysis.This dissertation selects D steel enterprises as research samples for empirical analysis,and then gives suggestions for the improvement of enterprise energy efficiency.Finally,the sixth chapter summarizes and forecasts,analyzes and summarizes the research content of this dissertation,and puts forward the shortcomings of this dissertation.
