Geographic Factors Affecting the Presence of Transhipment Services in Regional Maritime Container Markets

区域海运转运服务的分析已经将港口和航运商纳入研究范畴，但忽视了区域海洋盆地地理因素的影响。由于参与海运集装箱货运市场的过程与其他运输市场的过程具有可比性，因而本文认为和海盆形态有关的属性也应考虑在内。研究结果显示，转运服务与那些靠近海盆的区域具有相关性。本文将重点对以下问题进行阐述：过去经常用来直接或间接判断转运服务的传统分析方法；通过估计一个地区相对于自身吞吐量的转运率来判断部分地理区域在转运服务中的角色；通过区域海盆形态和社会经济属性相关的综合变量，构建能够判别转运服务的统计模型.

The presence of transhipment services in a region has previously been analyzed relative to ports and shippers with no consideration to the geographical factors of the sea basin serving the region. We hypothesize that attributes related to basin morphology also should be considered, as the processes involved in the maritime container freight market are comparable to processes in other transport markets. We show that transhipment services are relevant in those regions with closed sea basins. This article addresses the following issues: the traditional analytic methods used to determine, directly or indirectly, the presence of transhipment services; the role of transhipment in some geographic regions by estimating the rate of transhipment relative to throughput for each region; and the estimation of a statistical model that can determine the presence of transhipment by means of aggregate variables related to the morphology of a sea basin serving each region and to the socioeconomic characteristics of the region served.
