Manufacture of textile and wearing apparel is one of the most competitive industries in China. This paper estimated the international market share，trade competitiveness index（TCI），revealed comparative advantage index（RCA），relative trade advantage （RTA） of the textile and apparel made in China during 2000 to 2013 and found that：China is very competitive judging from the export situation. This competitiveness had been slightly weaken while judging from both export and import situation，but China was still among top 20 most competitive economies in the world. In recent years，China face fierce competition from India，Palestine and other developing countries who have cheaper labor costs and devour China’s market share in developed economies. It can be predicted that in the next few years，the Chinese international competitiveness in textile and apparel will continue to be eaten away. In order to deal with the fierce competition，Chinese firms should further diversify export markets，reduce their dependence on low-cost labor force，and promote the value chain position.
