China foreign trade index data

  The shipbuilding industry constitutes an integral component of China's national economy. It not only provides essential equipment for marine resource development but also furnishes critical infrastructure for global trade. From January to April 2021, global orders for large container ships reached 6.361 million compensated gross tons (CGT), with China accounting for approximately 50% of the market share. Maritime transport represents a vital element for China's participation in the international division of labor and the formation of international competitive advantages. Distinct from other transportation modes, maritime transport offers significant benefits such as large capacity, long-distance capabilities, cost-effectiveness, and low-carbon environmental friendliness, making it the predominant mode of transport in international trade. The level of development and convenience of maritime transport has become a crucial factor influencing a nation's cost advantages in international competition, serving as an essential component for every country's participation in the global division of labor and the establishment of competitive advantages.

  Detailed maritime shipping data plays an exceptionally important role in domestic trade research. Therefore, CnOpenData introduces China's ship industry dataset, which encompasses information on vessels registered in China from 1975 to the present, facilitating relevant academic investigations.
