英文摘要：

This paper constructs a new framework to measure the imports technical structure , analyzes its comparative advantage changing in China, and compares Chinese imports structure with 8 developed countries as well as another 8 developing countries. The results show that, from 2000 to 2010, the level of Chinese imports technical structure is firstly decreased and then increased, and in recent years, it has relatively fast growth. The middle-technology manufactured goods has become the largest imports in China. There are different import structures for China because of the different export counties. The developed countries mainly export the high technology industrial manufactured goods to China, and the developing countries mainly export primary products and metal manufactured goods to China. The developed countries monopolize the Chinese imports of high technology manufactured goods, and their comparative advantage increase faster, The comparative advantage of Japanese high technology manufactured goods has a low level and large imports, while that in USA, Germany and France are all high level and small imports. It is important for China to increase the imports of high technology manufactured goods from the western developed countries in future.
