摘要
本文利用数据包络分析法(DEA)对我国50家主要沿海港口1999—2002年的经营效率进行总体分析与评价,并利用Malmquist生产率指数对这些沿海港口的效率变动进行分析与评价。研究结果表明,我国沿海港口存在严重的投入拥挤与资源浪费现象;同时,各区域的沿海港口在总体效率、纯技术效率与规模效率方面存在地区差异,沿海港口的纯技术效率在下降。这些结果表明,要从根本上提高港口经营效率,一方面,必须整合港口资源,防止盲目扩大港口的基础设施;另一方面,通过港口与其他系统协调发展来消除影响港口效率提高的因素。
The paper analyzes and evaluates 50 sea ports with data envelopment analysis on the whole. In addition, it evaluates the changes of efficiency of these sea ports. The result shows that serious input crowding and resources waste exist in our sea ports;the economic efficiency, pure technical efficiency and scale efficiency of different areas of sea ports are different. The pure technical efficiency of these sea ports is decreasing. This implicates that the efficiency of sea ports can only be increased by integrating all these ports resources and avoiding the trend of enlarging the infrastructures of sea ports unrealistically on the one hand, and harmonizing the ports system and the other relevant systems.
