Maritime is a very competitive industry in global market. In addition to political, economic and prosperity, container carriers have to confront oil prices and climate. It gets high risk and uncertainty in operation. The threat of oversupply of capacity will affect the operation and development of container carriers. Costs is aggravated on container carriers due to they brought too many new vessels when previous boom but economic declined soon. Fleet deployment is a big issue when making operational strategies and plans. Container carriers have to plan how to purchase and lease vessels. People said that the proportion of owned container vessels of Europe container carriers is lower than Asia container carriers. Europe container carries may not spend too much cost to purchase container vessels so it would be more flexible to lease container vessels and able to deploy container vessels in/out of route and create brand new service more mobility. For this reason, operating performance is better than Asia container carriers. This study is base on secondary data from Alphaliner, Containerisation International and American Shipper database and periodical in 2007 and 2008: net profit, total revenue, the numbers of owned, leased and operated container vessels. The 15 major container carriers are divided into three segments: Asia-Chinese, Asia-Non-Chinese and Non-Asia container carriers. The General Linear Mode is practiced on these to find out if any impact or correlation from the proportion of owned container vessel to performance. The conclusions of this study are as following. 1. It¡¦s no correlation between the proportion of owned container vessels and net profit and total revenue in 2007 and 2008 2. The proportion of owned container vessels can not be fixed at a value 3. The proportion of owned container vessels is dynamic, may not be operated by container carriers.
