Research On Operating Efficiency Of Guangzhou Port Company Based On Two-stage DEA Model

80% of the world's goods are transported through the port.Since the reform and opening up,the port has taken the lead in participating and has achieved rapid development.In 2017,the global economic growth rate was 3.6%,which was not only higher than the average annual growth rate of 3.3% in 2008-2017,but also higher than the historical average growth rate of 3.4% in 1980-2017.Benefiting from the stabilization of the global economic growth,the global trading environment has improved.Therefore,the international container market environment has warmed up,and the throughput growth of major ports in the world has been outstanding.In 2017,the world's top 20 ports completed container throughput of 335 million TEU,a year-onyear growth rate of 5.6%,much higher than last year's growth rate of 1.7%.In the top 20 global container throughputs in 2017,Chinese ports accounted for half of the total.With the in-depth development of the national “One Belt,One Road” strategy,port enterprises must actively connect and serve the national development strategy.Although China's port enterprises have achieved sustained and rapid development,their growth still faces the problems of inefficient development such as extensive development and low management level.As one of the best port companies in China,Guangzhou Port is located in the GuangdongHong Kong-Macao Greater Bay Area.At the same time,it faces opportunities and challenges,and it is extremely urgent to improve the company's operating efficiency.In this paper,17 listed port companies are selected as comparative analysis samples,and the two-stage DEA model is adopted as the main research method.The operation process of Guangzhou Port is divided into the revenue stage and the profit conversion stage,in which the labor,business expenditure and total asset investment are selected as inputs indicators,the main business income as an intermediate indicator,and gross profit and operating profit as an output indicators.Using the CCR model and the BCC model,the technical efficiency,pure technical efficiency,scale efficiency and scale return of Guangzhou Port are measured in stages.Finally,the operating efficiency is analyzed in detail through weight,projection and shadow price analysis,and then the problems existing are found and suggestions for improvement are put forward.
