  Ships serve as the most critical transportation vehicles in international trade, with global demand. However, shipbuilding manufacturing remains concentrated in a few countries due to comparative advantages in factor endowments. The current supply-demand dynamics in the shipbuilding industry facilitate the global circulation of marine products, exposing shipbuilding enterprises to worldwide competition while accessing international markets.

  The management of shipbuilding enterprises encompasses various dimensions including design management, cost management, material management, component management, production site management, and personnel management, presenting exceptional management complexity and exhibiting extremely strong industrial correlations. This stems from the operational reality that shipbuilders typically cannot await complete technical documentation before commencing production, instead adopting concurrent design-production-modification processes. Moreover, stringent temporal constraints between components and rigorous requirements for system completeness necessitate tightly interlinked project workflows. These characteristics demand enterprises to possess advanced management capabilities, intensive management practices, and senior management personnel thoroughly familiar with entire shipbuilding processes and technologies. Additionally, close attention must be paid to collaborative relationships with associated enterprises within the industrial chain.

  Consequently, constructing a large vessel requires establishing close cooperative partnerships with multiple marine product suppliers. Capitalizing on this context, CnOpenData presents the Directory of Marine Product Suppliers in China, aggregating supplier information from two distinct sources to provide robust data support for international trade and related research.
