摘　　要：文章利用2000-2017年中俄水产品出口贸易数据,将中俄双边水产品出口增长分解为扩展边际、价格边际和数量边际三个方面,并通过对三元边际增长率和贡献率的测算分析中俄水产品出口贸易增长的主要动力。结果表明:中俄水产品出口贸易总额增长较快,但两者之间一直处于贸易逆差状态;两国水产品出口种类虽有相似之处,但主要出口品种仍有差异;同时,俄罗斯水产品出口中国的扩展边际高于中国水产品出口俄罗斯的扩展边际;相反,中国水产品出口俄罗斯的价格边际高于俄罗斯水产品出口中国的价格边际,但前者的变动幅度大于后者;俄罗斯水产品出口中国的数量边际变动幅度较大,中国水产品出口俄罗斯的数量边际变动幅度较小;多数时期,中国水产品出口俄罗斯主要依靠扩展边际的增长,俄罗斯水产品出口中国主要依靠数量边际的增长。Based on the data of Sino-Russian aquatic product export trade from 2000 to 2017,the growth of bilateral aquatic prod⁃uct export between China and Russia is divided into three aspects:expansion margin,price margin and quantity margin,and the main driving force of the growth of Sino-Russian aquatic product export trade is analyzed by calculating the three-way marginal growth rate and contribution rate.The results show that the total export trade of aquatic products between China and Russia has in⁃creased rapidly,but the two countries have been in trade deficit.Although there are similarities in the types of aquatic products ex⁃ported between the two countries,there are still differences in the main types of aquatic products exported.Meanwhile,the expan⁃sion margin of Russia’s aquatic exports to China is higher than that of China’s aquatic exports to Russia.On the contrary,the price margin of Chinese aquatic products exported to Russia is higher than that of Russian aquatic products exported to China,but the variation range of the former is greater than that of the latter.The quantity marginal change range of Russian aquatic products ex⁃ported to China is large,and the quantity marginal change range of Chinese aquatic products exported to Russia is small.Most of the time,the export of Chinese aquatic products to Russia mainly depends on the expansion of the marginal growth,while the export of Russian aquatic products to China mainly depends on the growth of the quantitative margin.
