中日韩三国在货物贸易上具有很强的相互依赖性．不仅贸易专业化指数一直处于较高位置，而且进出口产品在最终用途上也是互补的。消费品占据了中国对日韩出口的较大比例，而中国自日韩进口则以中间品和资本品为主。中国对日韩出口的技术水平低于自日本、韩国进口的技术水平。中国自日韩进口显著地促进了中国对日韩出口的技术复杂度，而且这一作用在中国高进口渗透率、低技术差距行业表现得更为明显。国内企业须加大自身研发经费投入，改善人力资本质量，提高技术吸收能力，以获得更多的进口技术溢出收益。

China, Japan and ROK depend each other strongly in trade, not only higher TSC but also complementary tradable goods in end＇use. China exports a large proportion consume goods to Japan and ROK, but imports mainly intermediate and capital goods from them. Export sophistication of China is lower than that of Japan and ROK. China＇s imports from Japan and ROK have contributed significantly to China＇s export sophistication, and far more dramatic in China＇s high import-penetration, low technology gap industries. Domestic enterprises need to increase their R＆D expenditure, improve the quality of human capital and absorptive capacity to get more import spillover benefits.
