中文摘要：
粮食作物良种补贴政策是农业稳粮增收的重要保障,也是农业提质增效的重要支撑。基于中国省际面板数据研究表明,粮食作物良种补贴政策对我国粮食增产的贡献率为23.70%,且粮食非主产区的粮食作物良种补贴政策效果远优于粮食主产区。因此在＂农业三项补贴＂改革进程中,一方面,补贴资金不应局限于耕地地力提升和粮食适度规模经营,还应向属于绿箱补贴范畴的良种良法配套技术推广及应用等方面转移或倾斜;另一方面,对粮食非主产区的改革速度及力度应缓于、弱于粮食主产区,进一步释放粮食作物良种补贴政策在粮食非主产区的政策效果,避免政策一刀切导致效率损失。
英文摘要：
The improved grain variety subsidy policy is an important strategy to guarantee stable grain yield and steady income growth for farmers and to support the improvement of agricultural quality and efficien-cy. The research shows that the contribution of improved grain variety subsidy policy to grain production is 23.70% in China,and the efficiency of improved grain variety in major grain production areas is much higher than that in the non-major grain production areas based on the provincial panel data. Thus in the process of three-agricultural subsidy reform,on the one hand,the subsidy capital should not be limited in promoting the quality of farmland and practicing proper scale management of grain. It also should be transferred or tilted to-wards the extension of matching technology of improved seed and methods which belong to green box policies. On the other hand,the speed of reform in non-major grain production areas should be slower and the strength weaker than that in major grain production areas in order to further release the efficiency of policy in the non - major grain production areas and avoid the loss of policy efficiency because of policy uniformity.
