This paper tries to use the data of 1998-2014 about nine departments (department of food, beverage and tobacco, department of fabric and clothing, department of car and motorcar and relative spare and accessory parts, department of medicine and the medical machine, department of culture, sports and relative equipment, minerals, building materials and chemical products division, house appliances division, computer auxiliary equipment division and else departments) to make the regression by Eviews 8.0. We find that department of food, beverage and tobacco and department of car and motorcar and relative spare and accessory parts, department of medicine and the medical machine, department of culture, sports and relative equipment do have crowding-out effect of exports on domestic consumption. Finally, in response to the policy of expanding the demand by analyzing the empirical result, we provide some recommendations from the perspective of export trade.
