| Nowadays the scale of container ships keep on rapidly increasing, which loading quantity reaches 13000TEU, while fast growth and globalization of world economy makes container shipment develops quickly and large-sized. Super sized ship is good for lowering the ocean cost by shipping circle. But international shipping market is a not static market with periodic valley and peak effected by world economy, trade, business, technology and natural environment. It is certificated by history that blindfold optimize will leads to ponderous burdens.Since 2005 after the business peak time of 2004, the continuous increasingly growth of container shipment is weakened, especially on the sino-europe liner, and super-sized container ship are used, which makes loading quantity decreasing and freight rate falling downUnder this situation, does super-sized ship still hold advantage of cost? Is there any necessary for keeping on building to increase the liner scale? That is to say, Should we get the prospective result through enlarging the scale of vessel?Sino-EU trade keeps 1st among china foreign trade. In 2005, the total amount reaches 217.31 billion US Dollars, rising up 22.6%. With the amount growing up, the quantity of cargos on this liner is quite big. So This liner means "golden liner" for every carrier with drastic competence. It is necessary to know about configuration of vessels sizes and analyze future development.This paper is to analyze global transportation market from the micro and macro-economical point of view by marginal cost research, the advantage and disadvantage of different size of vessels underdifferent circumstance to find out economical and appropriate size of vessel for a certain liner. That is to say, to demonstrate the results of multi-sized vessels on the sina-europe shipping liner. |
