Based on distributed lag regression model , the author of this paper studies transmission mechanism between domestic and the Chicago futures market with soybeans ,soybean meal and soybean oil .As we can see from the conduction characteristics on variety of beans between Dalian Futures Exchange and the Chicago futures market , transmission between futures prices of beans at home and abroad shows asymmetries .Overall ,our bean futures price on the Chicago futures market is more important than the influence of the Chicago futures market on China's futures market . It is significant that our Dalian soybean and soybean meal futures are Granger cause of soybean meal futures in Chicago but the opposite is not true .Through the transmission between Dalian soybean oil futures and Chicago soy oil futures prices are reciprocal causations ,as can be seen from the regression results ,the influence of our Dalian soy oil futures prices on the Chicago soybean oil is greater than that of the Chicago soy oil futures on Dalian soybean oil .%用分布滞后回归模型分别研究大豆、豆粕和豆油在国内期货市场和芝加哥期货市场间的传导。从豆类各品种在大连期货交易所和芝加哥期货市场之间的传导特点可以看出，豆类期货价格在国内外的传导具有非对称性。总体来说我国豆类期货价格对芝加哥期货市场的影响力要大于芝加哥期货市场对我国期货市场的影响力，特别显著的是我国大连大豆和豆粕期货都是芝加哥大豆和豆粕期货的格兰杰原因，而反之不成立。虽然大连豆油期货和芝加哥豆油期货价格间的传导互为因果，但是从分布滞后模型的回归结果可以看出，我国大连豆油期货对芝加哥豆油期货价格的影响力要大于芝加哥豆油期货对大连豆油期货的影响力。
