Abstract Accepted
Under the background of marine development strategies such as the construction of a "maritime power" and the 21st Century Maritime Silk Road, China, as the largest ocean economy in the world, has gradually expanded the hinterland of the marine economy to affect the rapid development of the inland economy, and the ocean industry is becoming a powerful driving force for the domestic economy and even the global economy. Based on the input-output tables of 142 sectors of marine economy in 11 China’s coastal provinces, this paper comprehensively adopted the input-output analysis method, hypothesis extraction method and structural path decomposition analysis method to track the implied value added distribution pattern of marine economic industry chain, and revealed the industry and regional heterogeneity of marine industry value added distribution along the industry chain. The implied value added of the upstream and downstream levels of China's marine industry chain was generally much lower than the direct value added. The implied value added of the marine scientific research, education, management and service and coastal tourism industry chain was roughly distributed in the service industry and decreased layer by layer. And the distribution of the value added of marine communications and transport and marine fishery had obvious regional heterogeneity at all levels of the industry chain. The value added of the industrial chain of the marine engineering construction was mainly concentrated in the upstream of the industrial chain.
