历史上我国大豆生产自给有余,在国际贸易中是个净出口国家,近年开始逆转,自1995/96年度起转化为净进口国。伴随大豆进口数量的增加,国内大豆消费中泊来品比例相应增加。在国际贸易中,我国豆粕的进出口贸易和大豆一样同步发生变化。进口豆粕从某种意义上说如同进口大豆,按每百公斤大豆出78公斤豆粕折算,把进口豆 Historically, China’s soybean production was more than self-sufficient, and it was a net exporter in international trade. It has been reversed in recent years and has been transformed into a net importer since 1995/96. With the increase in the number of soybean imports, the proportion of domestic consumption of soybeans has increased correspondingly. In international trade, the import and export trade of soybean meal in China has changed in the same way as soybean. Imported soybean meal is in a sense similar to imported soybeans. It is calculated by converting 78 kg of soybean meal per 100 kg of soybeans to imported beans.
