Research On Sino-Japan Intra-industry Trade Of Aquatic Products

China and Japan are neighbors in accordance with the water, and both are world’s two largest producer and trader of aquatic products. Aquatic products intra-industry trade between China and Japan, which has important influence to the global trade development of aquatic products, has experienced slow development, steady development, fluctuations and gradually reduce four stages. And China’s aquatic products exports face fierce international competition while trade frictions occur frequently between China and Japan that main caused by aquatic products safety problems.Using the trade data from 2001 to 2013 and HS coding system, calculate the degree of Sino-Japan intra-industry trade of aquatic products with G-L index and GHM index method, and analysis of trade trends, and determine vertical or horizontal intra-industry trade type. And results show that the intra-industry trade of aquatic products between China and Japan is increasing, HS 0303, which on behalf of frozen fish, performs noticeably well. But the type of intra-industry trade is vertical.Influencing factors of Sino-Japan intra-industry trade of aquatic products mainly include economic disparity, income inequality, the economic opening rate and FDI. Build the regression model of influencing factors with common panel data regression and panel threshold regression, and results show that the gap of economies of scale has a positive effect, while the per capita income disparity showed the opposite effects in two threshold which causing by economic scale. To be specific, when the gap of economies of scale is relatively large, the per capita income gap has a negative effect, whereas it has a positive effect. Opening degree determines the convenience of aquatic product trade and it certainly has a positive effect while FDI in China have obvious alternative effects on Japanese direct export of aquatic products from China, and weaken the Sino-Japan intra-industry trade of aquatic products.China should integrate national strategy, industry strategy and enterprise measures to promote Sino-Japan intra-industry trade of aquatic products. At the national strategic level, China should keep sustained and rapid development of national economy, and gradually improve the national quality of daily life and adjust consumption structure, and promote the foundation of CJKFTA; At the industrial strategy level, we should form industry cluster of aquatic products and realize economies of scale, improve the technology contents of aquatic products, enhance the added value of the industry using positive marketing measures; At the enterprise measures level, fishery cooperation should carry out the deep processing of aquatic products and pay great attention to product awareness and resource sharing with related companies, thus improve the international competitiveness of aquatic products.
