| 摘 要： | 为剔除环境变量和随机因素的影响,更加准确地评价港口效率,运用三阶段数据包络分析(data envelopment analysis,DEA)模型对2010年和2017年我国长江干线20个主要内河港口效率进行测度评价。结果表明:长江干线各主要港口,特别是长江干线中上游港口的规模效率相对较低,港口岸线资源、土地资源、设施设备和建设投资等要素投入相对分散,尚未形成规模效应;部分港口存在投入拥挤和产出水平低的现象,资源浪费问题突出。需要根据各港口发展实际,优化资源配置,提升港口效率。

| Abstract: | To eliminate the impact of environmental variables and random factors to evaluate the port efficiency more accurately, the three stage data envelopment analysis (DEA) model is adopted to measure the efficiency of 20 major inland river ports along the Yangtze River trunk line in China in 2010 and 2017. The results show that: the scale efficiency of the major ports along the Yangtze River trunk line, especially the upper and middle reaches, is relatively low, the input of port shoreline resource, land resource, facilities and construction investment is relatively scattered, and the scale effect has not been formed; some ports are of heavy investment and low output, and the port resources are wasted seriously. It is necessary to optimize resource allocation and improve port efficiency according to the actual development of each port. |
