“一户一田”会影响粮食单产吗?——基于山东省506个农户的实证分析

Will “one household one plot” affect the grain yield per unit area: Based on the empirical analysis of 506 farmers households in Shandong Province

为进一步释放土地制度改革红利,保障粮食安全,基于山东省2地市6县市区506个农户的调查数据,利用Cobb-Douglas生产函数探究“一户一田”对粮食单产的影响。结果表明:1)实施“一户一田”会增加粮食单产,即实施“一户一田”与小麦和玉米单产存在稳定的正向关系。2)实施“一户一田”对不同农户群体影响存在差异,即实施“一户一田”后,仅农业劳作和家中非农劳动力少的受访农户其小麦和玉米单产增幅更大。3)农户生产经营培训情况、农民合作社员身份、村组土地质量等因素对粮食单产有促进作用,参加过生产经营培训、合作社成员和土地质量高的受访农户其粮食单产更高。因此,政府应尊重民意,鼓励村组因地制宜分类实施“一户一田”,同时优化村组生产条件,从而提高粮食产量,实现稳产增产。

To further release the dividends of rural land system reform and ensure food security, based on the survey data of 506 farmers in 2 cities and 6 counties in Shandong Province, Cobb-Douglas production function was used to explore the impact of “one household one plot” on grain yield per unit area. The results showed that: 1) Implementing “one household one plot” increased grain yield per unit area and it had a stable positive relationship with wheat and corn yield per unit area. 2) The implementation of “one household one plot” has different impacts on different peasant household groups. After the implementation of “one household one plot”, the per unit yield of wheat and maize of the peasant households with less agricultural work and non-agricultural labor at home has a greater increase. 3) Factors such as farmers’ production and management training, farmers’ cooperative membership status, and land quality of village groups have a positive effect on grain yield per unit area, and the grain yield per unit area of farmers who have participated in production and management training, members of cooperatives and high land quality are higher. Policy implications are proposed in this study as follows: The government should respect public opinion, encourage village groups to implement “one household one plot” according to local conditions and improve the food production conditions, increase grain production and achieve stable production and increase production.
