摘要
文章分析了农机社会化服务影响农户粮食作物种植面积的理论机制,并使用2016年中国劳动力动态调查数据,运用工具变量法进行实证检验。研究结果表明:第一,农机社会化服务对农户增加粮食作物种植面积具有显著的正向作用,农机社会化服务在粮食作物方面的高供给率与农户的高劳动力替代需求相匹配,促进了农业种植结构的“趋粮化”。第二,相比于非兼业农户,农机社会化服务对兼业农户增加粮食作物种植面积的促进作用更大,兼业农户通过使用农机社会化服务增加粮食种植面积,将有限的劳动力资源转移到非农领域,实现工资性收入基础上的家庭收益最大化。第三,相较于东、中部地区,农机社会化服务对西部地区粮食作物种植面积的增加效果更显著,表明优化西部地区农机社会化服务供给,更能促进农业种植结构“趋粮化”。第四,农机社会化服务显著增加了粮食作物种植面积占比,减少了经济作物种植面积占比。此外,还通过显著降低农户弃耕地面积,促进了农户耕地利用的“趋粮化”。最后,论文根据研究结论提出了政策启示。
This paper analyzes the theoretical mechanism of agricultural machinery socialization services affecting farmers’grain crop planting area,and uses the 2016 China Labor Dynamics Survey data to conduct empirical tests using the instrumental variable method.The research results show that:First,agricultural machinery socialization services have a significant positive effect on farmers increasing the planting area of grain crops.The high supply rate of agricultural machinery socialization services in grain crops matches farmers’high labor replacement demand,which promotes agricultural planting.The“grain trend”of the structure.Second,compared with non part time farmers,agricultural machinery socialization services have a greater role in promoting part time farmers to increase the planting area of grain crops.Part time farmers use agricultural machinery social services to increase grain planting area and transfer limited labor resources.To non agricultural areas,to maximize household income based on wage income.Third,compared with the eastern and central regions,the agricultural machinery socialization service has a more significant effect on increasing the planting area of grain crops in the western region,indicating that promoting the supply of agricultural machinery socialization services in the western region can better promote the“grain oriented”agricultural planting structure.Fourth,the socialized service of agricultural machinery has significantly increased the proportion of food crops planted and reduced the proportion of cash crops planted.In addition,it has also significantly reduced the area of farmland abandoned by farmers,promoting the“grain oriented”use of farmland by farmers.Finally,the paper puts forward policy implications based on the research conclusions.
