Ocean economic input-output tables of coastal provinces in China.

The ocean economic input-output (IO) tables are essential databases for analyzing the ocean economy. However, the IO tables issued by Chinese government's statistical department adopt the conventional economic sector classifications, which fall short in capturing the heterogeneity of the ocean and land sectors. To fill this gap, we used the stripping coefficient method to construct the ocean economic IO tables of 11 coastal provinces in China, relying on the latest official provincial IO tables in 2017 and ocean economy data published by official institutions. The provincial ocean economic IO tables, which reflect the interconnectedness among 13 ocean sectors and 42 land sectors, could be widely used to support the ocean policy evaluation at the provincial level. To clarify the interlinkage between Chinese ocean economies and foreign economies, we further differentiated the Chinese ocean sectors from a global multi-regional input-output table that contains Chinese provinces. This dataset could be used to evaluate the development of ocean economy in China from a global perspective.
