Abstract：Based on the historical data of corn and soybean prices at home and abroad，the authors adopt co-integration and error correction model，impulse response function to study the transmission channel of international price to domestic price in food market with the perspective of import trade. The transmission channels of international price to domestic price include direct import channel，imported product cost channel and import substitution channel in theory. The empirical test shows that the direct import channel and imported product cost channel in soybean market are relatively efficient，namely international soybean price has impact on the imported soybean price，which will in turn have impact on domestic soybean price，and it will finally have impact on domestic soybean oil price；however，the above two channels in corn market are inefficient，namely the international corn price has a significant effect on the import price of corn in China，while the effects of the import price on the domestic price of corn and corn starch in China are weak. The import substitution channel in both corn and soybean market are inefficient. Thus， China should，first，carry out the supply side structural reform in the agriculture industry that taking improving quality and efficiency as the purpose，increase science and technology investment in food production，arousing farmers’enthusiasm of food planting，and focus on the improvement of food supply quality and efficiency；second，China should adhere to the principle that the imported food can only be used as the supplement to the shortage or surplus of domestic food supply and demand，and remain firm in our commitment to pursuing food safety；and third，China should establish the price control system and risk prevention system for the food market，and prevent the impact of price fluctuation in international food market on domestic food market.
