Abstract: The export margin reflects the expansion mode and development prospects of a country′s exports. Although the trade growth can be achieved along all the margins, the contribution of different margins to trade growth and international competitiveness is different. Based on Chinese custom data in 2000-2006, the paper used the revised MS index, TC index and RCA index to measure the international competitiveness of Chinese cultural products on trading partner market, measured export margin of Chinese cultural products from enterprise-product-market dimension, and empirically studied the influence of export margin on the international competitiveness of Chinese cultural products. The results showed that the growth of Chinese cultural products export is mainly due to the growth margin of exporting enterprise number, followed by the intensive margin; intensive margin and the number of exporting enterprises enhanced the international competitiveness of cultural products, the category number had a negative impact on its competitiveness, and the trade density had no significant effect on international competitiveness. Therefore, China should further improve cultural market system, and encourage enterprises to export the cultural products along the intensive margin; further tap the connotation of Chinese culture, and cultivate more backbone cultural enterprises.

Key words: cultural products, export margin, international competitiveness
