摘要
【目的】研究农村劳动力转移对粮食生产的影响,并揭示农村劳动力转移促进粮食生产的内在机制。【方法】基于1999—2020年分省面板数据,构建动态面板模型、影响机制模型与分层回归模型,进行实证分析。【结果】(1)我国农村劳动力存在过剩供给,农村劳动力转移对粮食生产产生正向影响。(2)农村劳动力转移使得农户家庭工资性收入增加,提高了农村居民收入;农村居民收入的提高又增加了农用机械投入与化肥等农业资本投入,进而提高了粮食产量。(3)当前阶段,农业资本投入中主要是化肥使用对粮食生产的影响较为显著,农用机械投入的积极影响还有待挖掘。(4)相较于非产粮大省,土地投入对产粮大省的粮食生产至关重要。【结论】在关注粮食生产的同时,应创造条件促进农村劳动力转移。
[Objective] This study aims to evaluate research the influence of rural labor migration on grain production and reveal the internal mechanism of rural labor transfer promoting grain production.[Method] Based on the provincial panel data from 1999 to 2020,the dynamic panel model, impact mechanism model and hierarchical regression model were constructed to conduct empirical analysis.[Result]①Where is surplus supply of rural labor force in China,and the transfer of rural labor force has a positive impact on grain production.②The transfer of rural labor force increases the wage income of peasant households and the income of rural residents.The increase of rural residents’ income increases the input of agricultural machinery and fertilizer and other agricultural capital, thus improving the grain output.③ At present, the use of chemical fertilizer has a significant impact on grain production, while the positive impact of agricultural machinery has yet to be explored.④Land input is more important for food production in productive provinces than in non-productive provinces.[Conclusion] While paying attention to grain production,conditions should be created to promote the transfer of rural labor.
