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

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 technological 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 downward trend is obvious in recent years. The Korea's export products' domestic technological contents raises greatly and convergence to Japan. 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.
