摘要
基于2001—2020年省级面板数据,运用随机前沿模型分析了农业种植结构变化对粮食生产技术效率的影响。研究结果表明:第一,中国种植结构变化在南北方地区之间呈现出专业化分工的趋势;第二,劳动力投入、机械投入、化肥投入以及粮食播种面积均对粮食总产量有显著正向影响;第三,种植结构变化对于粮食生产技术效率有显著正向影响,且增加粮食作物播种面积占总农作物播种面积的比值可提升粮食生产技术效率,因此各地区应进一步深化专业化分工水平以提升生产技术效率。同时老龄化率、女性化率、受教育程度及人均机械化水平均对粮食生产技术效率有显著正向影响。
Based on provincial panel data from 2001 to 2020, the stochastic frontier model was used to analyze the impact of agricultural planting structure change on grain production technical efficiency. The results showed that: firstly, the change of planting structure in China showed a trend of specialization between the northern and southern regions.Secondly, labor input, machinery input, fertilizer input, and grain sown area all had a significant positive impact on grain total output. Thirdly, the change of planting structure had a significant positive impact on the technical efficiency of grain production, and increasing the ratio of the sown area of grain crops to the total sown area could improve the technical efficiency of grain production. Therefore, all regions should further deepen the level of specialization to improve the technical efficiency of production. At the same time, the aging rate, feminization rate, education level, and per capita mechanization level had a significant positive impact on grain production technical efficiency.
