港航上市公司成本效率评价

Evaluation on cost efficiency of listed port and shipping companies

针对港航企业在迅猛发展、取得良好的经济效益的同时,很少对成本进行探讨和评价的状况,运用随机前沿分析(Stochastic Frontier Analysis,SFA)理论建立成本效率评价模型,选取10个港航上市公司2001—2006年的面板数据,对其成本效率进行评价;发现港航上市公司的成本效率水平虽然逐年递增,但整体还不高,有较大的提升空间.从港航上市公司的长远发展来看,应进一步开源节流,控制总成本.

In view of the condition that the listed port and shipping companies seldom carry out cost evaluation and analysis while achieving a favorable profit by the rapid development, a cost efficiency evaluation model based on the stochastic frontier analysis （SFA） theory is built. Ten listed port and shipping companies＇ cost efficieneies are evaluated according to their panel data from the year 2001 to 2006. It is pointed out that although the cost efficiency level of these listed port and shipping companies has been increasing gradually year by year, there is still comparatively large space for further improvement, broadening sources of income as well as reducing expenditure, and controlling the overall cost should be done in the long run.
