摘　　要：港口是一个多时期多流程组成的动态复杂网络系统。本文以2013~2016年中国10个主要沿海港口为研究对象,综合考虑经济、运营、环境等多种因素,将港口分为生产运营阶段和盈利转化阶段,并运用动态网络SBM模型进行港口效率评价,同时考虑了港口内部结构和跨期活动因素,通过结转指标将不同时期的港口结构连接成一个动态的整体系统,构建了动态的考虑港口相邻阶段间相互活动和相邻时期间跨期活动的非线性目标规划效率模型。不仅反映了港口效率在时间序列中的动态变化,而且揭示了港口内部的薄弱环节,完善了现有港口效率评价中忽略跨期活动和内部结构影响的不足。实证结果表明:中国港口的生产运营阶段效率普遍高于盈利转化阶段效率,动态网络综合效率低下与盈利转化阶段效率低有较大的关系,港口碳排放量仍然有很大的减排空间,动态网络SBM模型比动态SBM模型区分力更强,更适于港口效率评价。The existing studies regard the port as a simple system and only consider the operational efficiency or environmental efficiency of the port.However,the port is a dynamic complex network system composed of multiple periods and processes.Therefore,this paper uses the dynamic network SBM model to analyze the dynamic network efficiency of 10 major ports in China from 2013 to 2016.This paper divides the port into production-operation stage and profit-conversion stage by comprehensively considering economic,operational,environmental and other factors.The dynamic network SBM model considers both internal structure and undesired carry-over activities of the port.It not only reflects the dynamic changes of ports efficiency in the time series,but also reveals the weak links in the port.It improves the existing port efficiency evaluation to ignore the carry-over activities and the internal structure.Finally,the empirical results show that the efficiency of the production-operation stage is generally higher than the profit-conversion stage,the overall-efficiency of the port is closely related to the efficiency of the profit-conversion stage,and there is a large space for CO_(2) emission reduction.
