摘　　要：本文首先从理论上构建了限量收购和无限量收购条件下各种粮食干预政策的产出效应模型。分析表明:在两种收购条件下补贴政策及相应的粮食价格对剩余产量是否有拉动作用取决于农户的生产行为是否受到收入约束,而在限量收购下的收购量对剩余产量存在正反双重效应。其次,本文以我国改革开放以来的粮食数据为基础对该结论进行验证,结果表明就全国平均意义上而言,补贴政策对剩余粮食产量拉动作用有限,而粮食价格的拉动作用则相对较大,说明农户生产行为并未受到收入约束,而限量收购下的收购量对剩余产量的双重效应几乎完全抵消,从而只影响总产量而不会引致扩散效应。The paper initially establishes theoretical model on output effect of various grain intervention pol- icies under both finite and infinite purchasing circumstances,followed by the conclusion that whether subsidy policy and grain price under both circumstances would increase surplus yield counts on realistic authenticity of the assumption that peasants conduct grain production con- strained by the income limits,in addition,purchasing quantity under finite purchasing system ex- erts dual influence,positive as well as negative.Then we conduct empirical test about the above conclusion based on Chinese grain data since reform and opening-up,which supports that little contribution to the increase of surplus yield from subsidy policy,combined with relatively signifi- cant effect of grain price on nationwide average reveals no income constraint,furthermore,both the dual effects of purchasing quantity under finite purchasing system almost counteract with each other which means it just to affect total yield,not issuing in diffusing effect.
