Taiwan is surrounded by ocean; shipping industry is well-developed in this island. Evergreen, Yang-Ming and Wang-Hai are very well-known and also big shipping company in the world. So the industry of ships machine parts should be very well-developed here in Taiwan, but truth is it not very well-developed here. The purpose of this study was to find out the rules when shipping industries purchase ships machine parts, also how they recognize the quality, brand and service of the products. The study used case methodology and interview to shipping industry in order to find out the reason why industry of ships machine parts was not well-developed here in Taiwan. Hope the results of the study could made some efforts to future studies.
