【摘要】：物流業(yè)作為服務(wù)業(yè)的重要組成部分,已經(jīng)成為落實擴大內(nèi)需經(jīng)濟發(fā)展戰(zhàn)略的重點,也是促進國民經(jīng)濟發(fā)展、產(chǎn)業(yè)結(jié)構(gòu)優(yōu)化升級的重要領(lǐng)域。近年來,物流業(yè)在國民經(jīng)濟和社會發(fā)展中的重要性日益增強,但我國物流企業(yè)的經(jīng)營效率整體水平還不高,經(jīng)營成本居高不下,阻礙了其對我國經(jīng)濟發(fā)展的支持作用。然而國際競爭日趨激烈,物流需求快速增長,新技術(shù)、新管理不斷出現(xiàn)、資源環(huán)境約束日益加強,對我國物流企業(yè)提出了更高要求,進一步提高物流企業(yè)的經(jīng)營效率就顯得尤為重要。本文以物流上市企業(yè)的經(jīng)營效率為研究對象,基于國內(nèi)外現(xiàn)有的研究成果,通過對現(xiàn)有企業(yè)效率評價方法的比較,發(fā)現(xiàn)DEA(數(shù)據(jù)包絡(luò)分析)在多投入多產(chǎn)出的復(fù)雜系統(tǒng)中優(yōu)勢較為明顯,因此選用DEA方法為物流企業(yè)效率評價方法。從我國物流業(yè)特點與現(xiàn)狀出發(fā),充分考慮數(shù)據(jù)的可操作性,選取28家深滬兩市上市物流公司為代表,建立物流企業(yè)的投入產(chǎn)出指標體系,選取2008-2013年28家物流上市企業(yè)的固定資產(chǎn)總額、員工人數(shù)、營業(yè)成本和管理費用作為投入變量,主營業(yè)務(wù)收入和凈利潤為產(chǎn)出變量,對各個物流上市企業(yè)在各個年份的投入產(chǎn)出變量進行了Pearson相關(guān)性檢驗。然后運用CCR、BBC模型對這6年間各物流企業(yè)的技術(shù)效率、純技術(shù)效率和規(guī)模效率進行測算,從技術(shù)效率、純技術(shù)效率和規(guī)模效率三方面分別進行分析,結(jié)合公司發(fā)展現(xiàn)狀,分析了各物流上市企業(yè)歷年相對效率的變化,找出決策單元非技術(shù)有效的原因,有針對性的提出有效的參考改進意見。再用超效率DEA模型將技術(shù)效率為1的有效決策單元重新排序,評價相對有效的決策單元的效率水平高低。另一方面,提出物流企業(yè)經(jīng)營效率的內(nèi)部外部影響因素假設(shè),選擇2008-2013年面板數(shù)據(jù)建立Tobit模型,對影響因素進行回歸分析,運用Stata 12.0軟件進行計算,找到影響物流企業(yè)經(jīng)營效率的顯著因素并分析其影響作用的大小,提出相應(yīng)的改進建議。
[Abstract]:As an important part of the service industry, logistics industry has become the focus of economic development strategy to expand domestic demand, and it is also an important area to promote the development of national economy and optimize and upgrade industrial structure. In recent years, the importance of logistics industry in the development of national economy and society is increasing. However, the overall efficiency of logistics enterprises in China is not high enough, and the high cost of operation hinders its support for China's economic development. However, with the increasingly fierce international competition, the rapid growth of logistics demand, the continuous emergence of new technologies and new management, and the increasingly constraint of resources and environment, it has put forward higher requirements for our logistics enterprises. It is particularly important to further improve the operational efficiency of logistics enterprises. In this paper, the operating efficiency of listed logistics enterprises as the research object, based on the existing research results at home and abroad, through the comparison of the efficiency evaluation method of existing enterprises, DEA (Data Envelopment Analysis) advantage in complex multi input multi output system is obvious, so we choose DEA method for logistics enterprise efficiency evaluation method. From the characteristics of the logistics industry of our country and current situation, fully consider the data, selected 28 two cities of Shenzhen and Shanghai listed logistics company as the representative, input-output index system establishment of logistics enterprises, the total fixed assets, selecting 2008-2013 28 listed logistics enterprises the number of employees, operating costs and administrative expenses as the input variables, the main business income and net profit as output variables, listed for each logistics enterprise in each year in the input and output variables were analyzed by Pearson correlation test. Then, using the CCR BBC model on technical efficiency, the 6 years the logistics enterprises pure technical efficiency and scale efficiency was calculated from the technical efficiency, pure technical efficiency and scale efficiency of the three aspects were analyzed, combined with the current development of company, analyzes the change of the relative efficiency of listed logistics enterprise, to find out the reasons and effective technology the decision unit, aiming at putting forward effective reference. Using the super efficient DEA model, the efficient decision unit with a technical efficiency of 1 is reordered, and the efficiency level of the relatively effective decision unit is evaluated. On the other hand, assumptions puts forward the management efficiency of the logistics enterprise's internal and external influence, establish the Tobit model 2008-2013 panel data, regression analysis on the influencing factors, was calculated by Stata 12 software, find the significant factors affecting the operating efficiency of logistics enterprises and analyze the effects of the size, and puts forward the corresponding improvement suggestions.
