Finally, on the groundwork of above , it was concluded that China-US trade imbalance resulted from many external and intrinsic reasons such as international division of labor, US policy of controlling exports, instable domestic macro-economy in America, industrial transferring and globalization of economy Thereby, China should avoid"the trap of comparative advantage", and strengthen our comparative advantage so as to make our industry enter higher steps and ladders ,as should polish up Sino-American relations of division of labor ,and reduce the trade deficit concomitantly.
