Present situation and influence factors of national soybean import

The impact on Chinese soybean import was analyzed,including the domestic soybean yield,soybean oil demand,the domestic market price and so on.A multivariate linear regression model for quantitative analysis was established and the model was studied with multiple linear diagnosis and treatment,and heteroskedasticity test.The results showed that domestic soybean yield was highly negative relevant to soybean imports.When domestic soybean output increased by 1%,the imports would decrease by 0.93%.At the same time,soybean oil and meal output was highly postive relevant to soybean imports,and soybean oil and meal output increased by 1%,the soybean imports increased by 1.23%.
