| Abstract: | It is held that technological progress is the essential motive force of the development of intenational shipping and plays an important role in shipping competition. Through the characteristics of both isoquant and isocost curves and the marginal theory, this paper discusses the replacement of the productive parts and its optimized making-up. Moreover, on the basis of the changing features of the long-term average unit production cost in shipping, the problem of ship replacement is approached from the angle of optimal option. |
