民用船舶,作为大型机电产品,基本上均实行先订货后生产的经营生产方式。一艘船从签合同到建成交货,通常需要一年多到两年的时间,如果是由数艘船组成的一批船的合同,从签约到执行完毕可能要延续3年多时间。因此,1998年建成出口的船舶大体上是1996～1997年签约的,有些可能是1995年签的,并不反映当年的船舶出口形势。 Civilian ships, as large-scale mechanical and electrical products, basically implement the production and production methods after the first order production. It usually takes more than one year to two years from the signing of a contract to the completion of delivery of a ship. If it is a contract for a group of ships consisting of several ships, it may take more than three years from the signing of the contract to execution. Therefore, the ships built for export in 1998 were generally contracted from 1996 to 1997. Some of them may have been signed in 1995 and do not reflect the export situation of ships that year.
