中文摘要：

粮食直接补贴的增产效应表现在两个方面：一是扩大粮食种植面积；二是增加生产性投入，提高单位面积产量。笔者通过对河南省2004年～2009年粮食生产面板数据的分析，认为直接补贴对粮食主产区提高粮食产量的作用大干非主产区；对扩大种植面积而言，直接补贴效应系数低于价格效应系数；粮食增产依靠种植面积增加的空间越来越小；直接补贴政策与价格政策配合使用，才能促使农民增加粮食生产性投入。

英文摘要：

The paper analyzes grain production panel data from 2004 to 2009 in Henan Province It is found that the direct subsidy effect to increase the yield in primary areas are greater than that in non-primary areas; As for expanding the planting area, the direct subsidy effect coefficient is lower than the price effect coefficient; The space depending on expanding the planting area in production increase diminishes. Direct subsidy policy together with with price policy helps farmer to increase production input in grain.
