Analysis on Industrial Linkages and Driving Effects of Chinese Fishery Industry Based on Input-Output Model

Based on the national input-output (IO) tables from 2002, 2007, and 2012, this paper summarized the development of China's fishery industry and studied the industrial linkage and driving effects between the fishery industry and other sectors of the national economy. The results show that the output scale, gross domestic product, wages, and social welfare of China's fishery industry have all increased significantly, but the tax revenue and profits have decreased rapidly. The direct driving capacity, induced driving capacity, and total driving capacity of China's fishery industry all show a continuous downward trend, dropping from 1.1107, 4.8108, and 6.9478 to 1.0609, 3.4635, and 5.5293, respectively. The indirect driving capacity rises first and then declines, rising from 1.0263 to 1.1155 and then falling to 1.0049. The driving effect of China's fishery industry on other sectors is limited and shows a weakening trend.
