After wto , the port is not only a transportation center of goods and industrial production base , but also the very important component of logistics service network system , the position in the modern comprehensive logistics is very important Wto以后，港口不仅仅是货物转运中心和工业生产基地，同时也是现代物流网络体系的重要组成部分，在现代综合物流中的地位十分重要。
The proportion attaching to cargo of the allowances made in general average by reason of applying the third paragraph of this rule shall not exceed the cost which would have been borne by the owners of cargo if the cargo had been forward at their expense 因适用本条第三款，认作共同海损补偿而由货物分摊的部分不应超过假如由货主承担费用把货物转运至目的港所应支付的费用。
Supporting services these include various freight - related services , such as cargo - handling , container trucking and storage , warehousing , cargo transhipments , distribution and consolidation , barge handling , and 24 - hours computerised wagon tracking services 包括各种与货运相关服务，例如货物装卸、集装箱运输与储存、货物储仓、货物转运、分卸、装箱、趸船装卸，以及二十四小时货卡、集装箱追踪等服务。
Shenzhen would be the center of marine and logistic in south china ; the delivery center in the zhujiang delta ; the airlift center of the high additional value and high - tech products and the distributary center of cargo transferred in southeast asia in 2003s 预计到2003年，深圳将成为中国南部地区的航运和物流中心；珠江三角洲的配送中心；南中国地区高附加值、高新技术产品的空运中心；以及东南亚地区货物转运的分流中心。
The result indicates that improving the handling efficiency of berths is more efficient than extending dock berths in the view of ameliorating the operation condition of port , shortening the time stayed in port of ships , quickening the turnover speed of goods and reducing the freight cost 结合实例研究进行了港口参数的敏感性分析，指出提高泊位装卸效率比增建码头泊位更能改善港口的运营状况、减少船舶在港时间、加快车船货周转、降低货物转运成本。
A optimizing model of port construction scale is established in the thesis and the variants in the model are selected scientifically and suitably based on analyzing the each factor to influence the freight cost which occurs in transportation system . according to the model trait , every variant meaning and mutual relation between variants hi the model , the restriction condition of optimizing scale for port construction is educed , a simpler method which is called " climb hill " method is used to find the optimizing solution and corresponding computer program is developed 分析研究了运输系统中各种费用项目对货物转运费的影响程度，科学合理地选取费用项目，建立了港口规模优化模型，根据模型的特点和各参变量的物理意义及其相互关系导出了港口最优规模必须满足的条件，给出了利用相对比较简单的“爬山法”寻求最优解的方法，研制了相应的计算程序。
