中文摘要：

高技术制造业作为一国技术实力的核心，日益受到各国的重视。中日韩三国均为高技术产品出口大国，而且中日韩FTA谈判即将启动。在此背景下，本文在描述了中日韩三国高技术产品现状的基础上，采用Hausmann构造的出口复杂度指数，按HS4位编码测算了中日韩三国高技术产品的出口复杂度，并据此分析了中日韩三国高技术产品出口的技术特征和发展趋势。我们发现，虽然中国已经成为全球最大的高技术产品出口国家，但日本和韩国的高技术产品技术含量更高，高技术产业发展更加成熟，而且中国与日韩高技术产业出口产品的技术含量差距正在扩大。最后，本文就此提出相关建议，以促进中国高技术产业的技术水平进一步提升。

英文摘要：

As the core of a country＇s technological strength, high-tech industries become more and more important. China, Japan and South Korea are the major exporter of high-tech products and the FTA negotiations among them are about to start. In this context, this paper described the status of high-tech products of China, Japan and South Korea. It applied the export Sophistication index constructed by Hausmann to estimate high-tech products export Sophistication of China, Japan and South Korea＇s with HS 4-digit. Then it analyzed the technical features and the evolution trend of high-tech products export in China, Japan and South Korea. The authors found that although China has become the world＇s largest high-tech products export country, Japan and South Korea＇s high-tech products embodied higher technology and their high- tech industry are more mature, while the technology gap of high-tech industry exports between China and Japan-Korea is expanding. Finally, the paper put forward relevant proposals in order to promote the technical level of China＇s high-tech industry.
