港口效率测度是港口发展研究中的一个重要课题。本文选取总资产、在职员工人数、营业成本作为投入指标,利润总额和港口吞吐量作为产出指标,采用多产出随机前沿模型分析了我国14个港口上市企业的技术效率,得到了这些港口上市企业的效率的比较排序值,将我国上市港口企业分为三级梯队,并分析了影响港口效率的投入因素——总资产、在职员工人数、营业成本,为低效率港口提升港口效率提供了途径。
The measure of port efficiency is an important issue in port development research. In this paper, the total assets, the number of employees on the job, operating costs as input indicators, total profit and port throughput as output indicators, using the multi-output stochastic frontier model to analyze the technical efficiency of China’s 14 port listed companies, these ports listed According to the comparative ranking of the efficiency of enterprises, the listed port enterprises in our country are divided into three echelon teams, and analyzed the input factors affecting the efficiency of the port - total assets, the number of employees on the job, operating costs, providing a way for the port to improve port efficiency with low efficiency .
