摘要: 【目的】探索分析规模化经营对粮食生产效率的影响及内源性作用机理。【方法】基于山东省种粮户的调研数据,采用局部前沿效率方法与非参数核回归。【结果】整体上调研区规模化经营农户粮食生产效率低于非规模化经营农户,但不同作物之间的效率水平存在差异;规模化经营农户生产效率异质性较大,非规模化经营农户粮食生产效率相对趋同,原因在于粮食规模化生产对经营者的技术与知识储备要求相对较高,部分农户实行规模化经营的技术力量相对薄弱;规模化经营者知识与技术储备是影响其粮食生产效率的关键因素,劳动力投入对粮食非规模生产效率具有显著影响。【结论】地方政府在鼓励、推进规模化经营的同时,应注重规模化经营户生产技术水平的提升。

Abstract: 【Objective】 To explore and analyze the effect of large-scale management on grain production efficiency and its endogenous mechanism. 【Method】 Based on the survey data of grain farmers in Shandong Province, using the local frontier efficiency method and nonparametric kernel regression. 【Result】 Overall, the grain production efficiency of large-scale farming households was lower than that of non-large-scale farming households, but there were differences in the efficiency levels among different crops. The differences in the production efficiency of large-scale operation farmers are significant, and the grain production efficiency of non-large-scale operation farmers is relatively similar. The reason is that large-scale production of grain requires high technical and knowledge reserve of operators, and some farmers have weak technical strength to implement large-scale operation;Knowledge and technology reserve of large-scale managers are the key factors affecting their grain production efficiency, and labour input significantly impacts the non-large-scale grain production efficiency. 【Conclusion】 Local governments should pay attention to the improvement of large-scale operators’ production technology level while encouraging and promoting large-scale operation.

Key words: grain production and management, scale operation, partial front efficiency, kernel regression
