【摘要】：通过理论分析粮食补贴政策对粮食生产的影响机理,构建双对数生产函数模型,分阶段分品种对小麦、玉米、水稻和大豆四大主要粮食作物的粮食补贴投入产出作用效果进行实证分析,结果显示:亩均粮食补贴对玉米生产的投入产出作用显著,但作用效果被抵消了,亩均粮食补贴对其他作物的投入产出效果不显著;粮食补贴对劳动时间要素投入作用较为显著,特别是对玉米和小麦的劳动投入促进显著,而对水稻和大豆的作用效果不显著;粮食补贴提升了农户种粮的积极性,但产出效果不明显。未来粮食补贴政策应在建立市场价格机制下,进行结构性调整与改革,实行价格与补贴相分离,让补贴以要素投入合理化为基准,通过补贴满足不同作物生产收益所需。
[Abstract]:Based on the theoretical analysis of the influence mechanism of grain subsidy policy on grain production, the model of double logarithmic production function is constructed. The effect of grain subsidy on input-output effect of four main grain crops of rice and soybean was analyzed. The results showed that the input-output effect of grain subsidy per mu on maize production was significant, but the effect was offset. The input-output effect of grain subsidy per mu on other crops was not significant, the effect of grain subsidy on labor time factor was more significant, especially on corn and wheat, but the effect on rice and soybean was not significant. Grain subsidies promote the enthusiasm of farmers to grow grain, but the effect of output is not obvious. Under the establishment of market price mechanism, the future grain subsidy policy should carry out structural adjustment and reform, separate the price from the subsidy, let the subsidy be based on the rationalization of the factor input, and satisfy the needs of the different crop production income through the subsidy.
