cruise ship construction represents the highest level of shipbuilding industry. It needs strong support in terms of actual design，construction and supporting facilities. Many countries around the world master various types of large-scale ship construction technologies，but most of the cruise ship construction is in a blank state. Even if they spend a lot of human，material and financial resources，they still fail to fully master all the system technologies of cruise ship construction. Thanks to Europe’s good cruise market foundation and ship construction technology foundation，Europe has become the most important cruise construction base in the world，and is mainly concentrated in a few countries such as Italy，Germany and Finland. After years of development，it is in an absolutely leading position and systematically controls the construction technology of various types of cruise ships. As the cruise ship construction needs a perfect supporting system，a systematic and perfect cruise ship construction supporting manufacturer system is formed around the cruise ship construction shipyard，which is highly dependent on cruise ship builders，and some suppliers gradually become core suppliers. In addition to cruise construction，cruise maintenance is also an important link in the cruise industry chain and an important basis for ensuring the long-term safe operation of cruise. Due to the low degree of difficulty of cruise maintenance compared with cruise construction and the low concentration of cruise maintenance manufacturers，many manufacturers with ship maintenance experience can undertake certain cruise maintenance business. China is a world-famous ship building country，but the cruise ship construction is still at a very early stage. It cooperates with foreign cruise ship builders to promote domestic large cruise ships，and uses the original ship maintenance experience to carry out cruise ship maintenance，so as to provide more support for promoting the development of China’s cruise industry chain.
