Analysis Of Operational Efficiency Of Listed Companies In Logistics Industry Based On DEA And Malmquist Method

With the development of the modern economy,the important position of the logistics industry has become more and more prominent.As an increasingly systematic and integrated whole,it is changing the business model and production mode of our country and the status in the economic development has become more and more important.Based on this background,this paper evaluates the operating efficiency level of listed companies in China's logistics industry,and uses DEA,crossover efficiency and Malmquist method to analyze the operating efficiency of 38 listed companies in China's logistics industry.Firstly,it introduces the research background and research significance,and summarizes the research status of some scholars at home and abroad to draw the problems in recent research,and also explains the main contents of the research,research methods,innovation points and other issues.The main innovations of this paper are from "self-evaluation" to "he comment"and then "static" to "dynamic".The management efficiency is analyzed in many aspects from many aspects.Next,an overview of the concepts related to efficiency and operational efficiency is provided,followed by an overview of the selected DEA model,crossover efficiency,and related concepts of the Malmquist method.Then,an empirical analysis was conducted.According to the logistics industry under the industry classification criteria of Shenyin Wanguo,the data of 38 listed companies from 2013 to 2017 were selected for operational efficiency analysis.And the main business cost,net fixed assets,asset-liability ratio and current ratio are selected as input indicators,and the main business income,accounts receivable turnover rate and net profit are taken as output indicators.Firstly,using the VRS in the traditional DEA model,the "self-evaluation" of the 38 operating efficiencies was carried out,and then the "evaluation" was carried out by using the cross efficiency.Finally,the dynamic analysis of the 38 companies was carried out by using the Malmquist method.The analysis shows that the overall development level of China's logistics industry is relatively stable,and the management level and management ability of enterprises are greatly improved,but there will be certain volatility.Many companies still have increasing returns in scale and cross-efficiency.The analysis found that the average annual cross-efficiency level is low.In the end,we evaluated the total factor production efficiency of China's logistics industry.It is found that the main reason for the decrease in production efficiency in recent years is the reduction of technological progress and the ability to improve technology.And lack of technological innovation.Finally,combined with the above analysis,the related countermeasures to improve the operational efficiency of the logistics industry are proposed from two aspects of technological innovation and control cost.And put forward the shortcomings in the research and the prospect of the future development of the logistics industry.
