Abstract: Based on the WIOD input-output data from 2005 to 2014, this research calculates the export domestic added value of China’s marine service trade with eight other major sample countries through the non competitive input-output model, and evaluated the international competitiveness of China and its sample countries based on the adjusted IMS and RCA. The results show that the export domestic added value of China’s maritime service trade increases rapidly, but there is still a big gap with the United States. The growth rate of China’s IMS index is faster than that of France, Germany and Japan successively. The development potential of maritime service trade is great, but the RCA index is at a low level, and the maritime service trade has no competitive advantage. On this basis, it puts forward the countermeasures and suggestions to enhance the international competitiveness of China’s maritime service trade.

Key words: maritime service trade, international competitiveness, value added trade, non-competitive input-output model
