Research On The Evaluation Of Financial Performance Of Listed Companies In Gold Mining Companies Based On DEA

Gold is a national protective special mining species with dual properties of general commodities and currency.It plays a crucial role in responding to the financial crisis and safeguarding national economic security.Since 2002,after the establishment of the Gold Exchange in Shanghai,China's gold companies have begun to flourish.Since 2008,since the listing of gold futures,China's environmental market has gradually been integrated with the country's gold market.Since 2013,the international gold environment has become increasingly severe.The international gold price has continued to fall and China has also been affected.In recent years,relevant national policies have supported the Chinese gold industry and allowed it to develop rapidly.It can be seen that the development of the gold mining industry has been fluctuating over a long period of time,and that gold mining is the backbone of the country's economic development and the national financial security guarantee.Therefore,it is particularly important to conduct in-depth research on the gold industry and how to properly assess and predict the development of the industry.This article examines gold mining from the perspective of financial performance evaluation.It can grasp the specific performance of the entire industry,show the development trend of gold mining listed companies,and provide reference for corporate managers and corresponding recommendations.This paper mainly analyzes the financial performance of China's gold mining listed companies through the DEA method(data envelopment analysis theories and methods),based on the factors affecting the efficiency of the company.Established an evaluation index system for the efficiency of listed companies in gold mining,and selected 10 gold mining listed companies from 2013 to 2016 as samples to conduct horizontal and vertical case studies.First,select the total assets,main business cost,and net assets as input indicators.The main business income,net profit,and basic earnings per share are investment indicators,and then pass the BCC model(variable scale model).The above raw data are normalized,and then the DEA model is used to analyze the normalized data using DEAP2.1 software.The following conclusions have beendrawn: The overall performance of China's gold mining listed companies has been showing a good trend for the period 2013-2016,and it is on an upward trend.The performance gap among companies in the industry is not large.However,there are cases where invalid decision-making units exist,and the reason why the decision-making units are invalid is complicated.Most of them are invalid because of their scale,and some are due to technical inefficiencies,and there are also two reasons that lead to common causes.Finally,corresponding suggestions are given for the differences in the invalidity of each company's decision-making unit.I hope to promote the healthy development of China's gold mining listed companies.
