摘要：随着韩国与中国经济的快速发展, 中、 日、 韩三国产业结构与产业发展的差距有所缩小。当前三国之间的国际分工仍留有雁行模式的痕迹，制造业在三国均占有主导地位，但制造业内部各部门的发展水平仍有差距，三国在对外贸易中表现出来的产业互补性仍然较强。而另一方面,韩国同中国资本、技术密集型行业的发展对日本形成了竞争，韩国在少数劳动密集型行业同中国也存在竞争，三国产业在原先以互补性为主的基础上出现逐步增强的竞争趋势。本文首先以比较优势理论、竞争优势等理论为基础，分析了中日贸易发展现状、中韩贸易发展现状，以及中日韩贸易走势，进而分别运用贸易竞争指数和贸易互补性指数对中日韩三国的贸易竞争性和互补性进行探讨。然后，归纳了中日韩贸易竞争性与互补性对我国贸易的影响。

And on the other hand, South Korea and China's capital and technology intensive industry development to Japan formed the competition, South Korea in a few labor-intensive industry with China, too, has competition, in the previous three industries complementary to each other on the basis of mainly appear gradually enhance competition tendency. Because of this, the China, South Korea and Japan trade competitive and complementarity problems for promoting the development of trade has very important practical significance. Based on the theory of comparative advantage, competitive advantage theory as a foundation, analyzed the present situation of the development of the trade between China and Japan, China and South Korea trade development present situation, and the republic of Korea trade situation, and then use respectively trade competition index and trade of the republic of Korea complementary index of The Three Kingdoms trade competitive and complementary are discussed.
