Research On Performance Evaluation Of Steel Listed Companies Based On DEA

With the continuous progress of structural reform on the supply side in China,the problem of excess capacity in the steel industry has been alleviated to some extent,but the structural contradiction in the steel industry is still prominent,the proportion of low-end products is high,the proportion of middle and high-end products is insufficient,and the ability of scientific and technological innovation is insufficient.At the same time,international trade protectionism is spreading,steel exports continue to be under pressure,environmental protection pressure is increasing,and so on.The soaring cost of raw materials makes the profit margin of the whole industry low.In this context,if we want to improve the competitiveness and viability of the entire iron and steel industry,we should pay attention to the construction and improvement of the performance evaluation system of iron and steel enterprises.Constructing a scientific and applicable performance evaluation index system,selecting appropriate evaluation methods,conducting a scientific performance evaluation of China's iron and steel listed companies,andi finding problems in the economic activities of enterprises,thus putting forward countermeasures and suggestions for specific problems,which will help the company to improve its performance level and promote economic benefits.Referring to the domestic and foreign literature on enterprise performance evaluation,this paper summarizes the current status of performance evaluation research,and briefly describes the content,methods and paths of this study.This paper summarizes the basic concepts and theoretical basis of performance evaluation,briefly introduces the commonly used performance evaluation methods,and analyzes the feasibility of data envelopment analysis(DEA).According to the operating characteristics of the iron and steel industry,this paper comprehensively analyses the present situation of the development and operation of the iron and steel industry,summarizes the present situation of the performance evaluation of the listed companies in iron and steel industry,and constructs the performance evaluation index system of the listed companies in iron and steel industry based on the design principle of the index the current salary increase,total assets,main business cost and R&D expenditure as input indicators,and Income,earnings per share and total profits and taxes are output indicators.By choosing the BBC and Malmquist models of DEA method to evaluate the performance of 26 Steel Listed Companies in China from 2013 to 2017,the following conclusions can be drawn:The comprehensive eff-iciency,pure technical efficiency and scale efficiency of iron and steel listed companies are basically higher than 0.9;The value of scale efficiency decreases slightly,and the number of companies with increasing returns to scale is slightly larger than that with decreasing returns to scale;The data of iron and Steel Listed Companies in 2017 are analyzed by projection,and the improvement plan for iron and steel listed companies that need to improve their performance level is provided;Total factor productivity(TFP)is only greater than 1 in 2014-2015,and it has declined in other periods.Finally,based on the results of empirical analysis,some suggestions are put forward to speed up strategic restructuring,improve technology level,improve management level and adjust product structure,aiming at promoting the performance of steel listed companies.
