我国粮食对外贸易中的一个“悖论”及其成因探析

A Paradox in the Foreign Trade of Grain in China and its Causes

按照比较优势理论,我国应净进口粮食这一土地密集型产品。但本文在实证分析后却发现,1997年以来我国已经成为粮食产品的净出口国。粮食产品较低的“可贸易度”制约了市场机制及比较优势作用的发挥。但从中长期来看,粮食产品的“可贸易度”会呈上升态势,发挥国内外“两个市场”的作用对增强我国粮食安全保障具有重要意义。

According to the theory of comparative advantage, China should be a net importer of grain. But based on demonstration analysis of China's foreign trade, it is said that China has been a net exporter of grain since 1997. The author thinks that the grain is not easy to trade and that has restricted the action of market economy and theory of comparative advantage. But, it is believed that the grain will be easier to trade in the future. It is very important to increase grain security of China by using domestic and international markets.
