摘　　要：一些学者认为,粮食产量低于一定的数量,就意味着出现了粮食安全问题或者存在粮食危机;播种面积低于一定的数量,意味着中国出现了粮食安全问题。但本文认为,建国以来的数次粮食价格上涨,与耕地面积没有直接关系。通过计量分析发现,影响粮食产量的主要因素是价格、政策、投入等因素,而非耕地面积。不能简单地将粮食产量与播种面积或者耕地面积挂钩,不能认为保有了一定的耕地面积或保证了一定的播种面积就必然保障一定数量的粮食产量。Some scholars argue that when the output of grain falls below a certain amount, there comes the problem of grain security or grain crisis; or when sown areas of farming land fall below a certain amount, there also comes the problem of grain security in China. However, this article found that there was no direct relation between the several price increase since the foundation of the People＇s Republic of China and areas of farming land. With empirical studies, the author found that the major factors that affect the output of grain are price, policy, investment, etc. but not areas of farming land. We cannot simply relate output of grain to areas of fainting land, and cannot conclude that a certain fainting land could guarantee a certain output of grain.
