This paper analyses the changes in the variety, price, and quality of Chinese export products, and their contributions to China’s export growth into the Korean market, using HS 10-digit highly disaggregated Korean trade data between the years of 1992 and 2008. In this paper, empirical methodologies for estimating the price level and quality level of Chinese products are developed. Our results show that China’s export growth is mainly explained by an increase in the intensive margin, and that the rise in the intensive margin is due to a decrease in price and an increase in quality of Chinese products. Even if an increase in product variety and a decrease in price have contributed to China’s export growth, the improvement in product quality is the main factor affecting China’s rapid export growth into the Korean market.
