摘　　要：基于2016年和2018年两轮中国劳动力动态调查(CLDS)数据,运用一阶差分模型,从土地转入户的视角考察农业补贴改革对粮食生产效率的影响。结果表明:(1)农业补贴改革显著促进了粮食生产效率的改善;从内部构成来看,农业补贴改革对规模效率的促进作用要强于对技术效率的促进作用。这一结论经过多种稳健性检验和控制内生性后依然成立。(2)机制分析表明,农业补贴改革通过促进农户扩大土地转入规模、增加农业生产投资和提高农业机械化水平,进而改善粮食生产效率。(3)农业补贴改革对粮食生产效率的改善呈现出一定的异质性,经营规模大、流动性约束强以及非粮食主产区的农户对农业补贴改革的反应更为敏感。研究发现有助于厘清农业补贴改革与粮食生产效率之间的内在联系,为进一步完善现行农业补贴政策、保障国家粮食安全提供经验证据。Based on the data of China Labor Force Dynamics Survey(CLDS)from 2016 to 2018,this paper uses the first difference model to examine the impact of agricultural subsidies reform on grain production efficiency from the perspective of farmers who rented-in land.The results are as follows:(1)Agricultural subsidies reform significantly improve the grain production efficiency.In terms of internal composition,agricultural subsidies reform have a stronger effect on scale efficiency than that of technical efficiency,and this finding still holds after various robustness tests and controlling for endogeneity problems;(2)Mechanism tests show that agricultural subsidies reform mainly improve grain production efficiency by promoting farmers to expand the scale of land transfer-in,increase investment in agricultural production,and improve agricultural mechanization;(3)The impact of agricultural subsidies reform on grain production efficiency shows certain heterogeneity.The reform plays a greater role in large-scale,strong mobility constraints,and non-major grain producing areas.The findings are helpful to identify the intrinsic relationship between agricultural subsidies reform and grain production efficiency improvement,and provide empirical evidences for further improving agricultural subsidy policies to ensure food security.
