Research on the impact of large-scale operation on food production：empirical test based on spatial econometric model

Whether large-scale operation can improve the efficiency of food production has been the focus of debate in the academic world. This paper studies the impact of large-scale operation in China on grain production， with a view to promoting the increase of grain production per unit. Based on 2006—2018 provincial panel data of the mainland of China， a spatial econometric model was used to study the impact of land management scale on grain yield. The results show as follows. Average sown area per household and grain yield have significant spatial autocorrelation， and average sown area per household has a significant impact on grain yield， showing a “U” curve relationship. In the long run， large-scale operation is conducive to the increase of grain yield. Therefore， centralized management of fragmented land is necessary to realize the improvement of the grain yield. At the same time， it’s also required to improve the professional quality of farmers， encourage various forms of large-scale production， and strengthen the construction of production conditions for intensification.
