东亚国家出口品的国内技术含量动态变迁研究

Research on the dynamic evolution of export products' domestic technological contents of East Asia countries

改进计算出口品的国内技术含量的基础模型,利用投入产出表和STTC REV.2三位码水平上的出口贸易等数据,测算了中国、日本、韩国和印度尼西亚等东亚经济体若干年份出口品的全部技术含量、国内技术含量和国内技术含量指数.结果表明:从20世纪90年代中期开始,中国出口品的国内技术含量呈阶段性上升趋势;加入WTO对我国出口品的国内技术含量的短期影响大于长期影响;虽然日本是东亚地区国内技术含量最高的国家,但近年来呈下降趋势;韩国出口品的国内技术含量稳步提高且向日本收敛,而印度尼西亚在提升出口品的国内技术含量方面业绩较差.最后,结合中国以及其它东亚三国出口品的国内技术含量的变迁趋势,提出了中国进一步推进对外开放和参与东亚区域经济一体化的一些政策建议.

This paper has improved the basic method to measure the domestic technological contents of export products. By using data in the input-output table and the export trade data on the SITC REV.2 level, it counts the whole technological contents, the domestic technological contents and the index of the domestic technological contents of export products in several years of East Asian economic bodies like China, Japan, Korea and Indonesia. The result shows that China＇s export products＇ domestic technologi- cal content is going through an upward trend since middle 90s, 20th century. Also, the short term impact of China＇s entrance into WTO on China＇s export products＇ domestic technological contents is greater than long term impact. Though Japan ranks the top in East Asian on domestic technological contents, its down- ward trend is obvious in recent years. The Korea＇s export products＇ domestic technological contents raises greatly and convergence to 3apan. Indonesia failed in improving its export products＇ domestic technological contents. Finally, in combination of the evolution trend of export products＇ domestic technological contents in China and other three East Asian countries, the article proposed some relevant policy recommendations under the background of further opening up and involving in regional economic integration in East Asia.
