Structure, conduct and performance are important elements in the economic analysis of an industry. This thesis identifies and discusses the sub-elements of structure, conduct and performance of the U.S. shipbuilding and repair industry and how these sub-elements interact. A brief history of the industry to the Merchant Marine Act of 1970 is presented. Structure sub-elements are comprised of concentration, production methods, labor, governmental influences, barriers to entry, demand for U.S. Navy and merchant vessels and financing methods. Conduct sub-elements consist of public policies, labor utilization, financing behavior, claims, competition, research and development and conglomerate behavior.
