大豆需求与全球资源的优化配置

The Real Demand behind the Soybean Import

供求决定价格,价格又反过来影响供求平衡。一方面,中国对大豆的进口需求是导致国际价格不断上涨的主要原因;另一方面,中国水产品出口价格的下降又刺激了美、日、韩等国对我国大虾消费的需求。大豆豆粕是大虾饲料的主要成分,欧美水产品的消费间接拉动了我国大豆的进口。除此,由于大豆属土地密集型农产品,利润率较低,在耕地资源短缺的条件下,我国应该生产那些劳动力密集、单位产量较高的农作物或收益较好的经济作物,进口土地密集型农作物。因此,进口大豆,出口大虾,符合全球资源的优化配置原则。

Price is determined by supply and demand. China imports a large number of soybeans which resulted in international market prices going up. At the same time, the Unites States, Japan, Korea and other countries import large quantities of shrimp production from China. The increase of shrimp consumption in western countries is one of the reasons that China import soybean. The marginal profit of soybean is lower than other crops and it take more arable land, so the soybean is the land - intensive agricultural products. Due to the shortage of arable land resources in China and according to the principle of comparative advantage, we should import the soybean and export the shrimp production.
