The foreign economy and trade of Guangdong has been impacted by the south-east Asian financial crisis in the late 1990s and the international financial crisis in 2008 during the recent 20 years since middle 1990s，with its trade structure and competitiveness being changed. In this report，all the export products are divided into four types：resource-intensive products，labor-intensive products，capital-intensive products and technology-intensive products，according to the factor intensities of themselves and then to be studied on the change of their competitiveness. RCA index and TC index are applied to measure the competitiveness of different types of the export products. The results show that the overall export competitiveness of Guangdong has been improved. Among，the competitiveness of labor-intensive products is strong，which is principally embodied in the manufacturing industries with traditional advantages like textile，clothing and ceramics. However，these export products remain in the bottom of the value chain. Second，a certain degree of revealed competitive advantage can be seen in technology-intensive products. This type of products are controlled by foreign capital，thus the equipment manufacturing industries with independent high and new technologies are lack of competitiveness. Last，competitiveness of capital-intensive products is weak while that of resource-intensive products come the weakest.
