This article describes the concept of modularization, modular building and modular network, analyses the condition of Chinese shipbuilding industrial organization and the position in the global value chain, pointing out the factors that hinder the construction of Modular Network of Chinese Shipbuilding, and provides the idea of the construction of Chinese shipbuilding modular network.
