【摘要】：文章在农村劳动力转移规模持续扩大的背景下,分析了非农收入对农业要素投入结构的影响机制,并利用2000~2013年省级面板数据,采用似无相关回归分析法验证非农收入对不同农业生产要素投入的影响。研究结果表明,从全国来看,农户存在合理配置家庭资源的自我激励,非农收入对农业机械、化肥和农药的投入均产生了显著的促进作用;分地区来看,由于经济发展水平和要素替代成本不同,非农收入对农业要素投入的影响呈现出明显的区域差异,东部地区改变传统农业要素投入结构的意愿最强,其非农收入对3种农业要素投入的影响均强于中部和西部地区;在以种植小麦为主的地区,农业机械投入的替代成本相对较低,受非农收入的影响强于以种植水稻或玉米为主的地区,要素投入结构变化以节约劳动力为主;在以种植水稻为主的地区,化肥和农药投入的替代成本低于农业机械投入,受非农收入的影响比以种植小麦或玉米为主的地区更显著,要素投入结构变化以节约土地为主。
[Abstract]:Under the background of the continuous expansion of rural labor force transfer scale, this paper analyzes the influence mechanism of non-agricultural income on the input structure of agricultural elements, and makes use of provincial panel data from 2000 to 2013. The effect of non-agricultural income on the input of different factors of agricultural production was tested by using the method of regression analysis. The results show that, from a national point of view, farmers have self-motivation to allocate household resources reasonably, and non-agricultural income has a significant impact on the input of agricultural machinery, fertilizers and pesticides. Because of the different level of economic development and the cost of factor substitution, the influence of non-agricultural income on the input of agricultural elements shows obvious regional differences, and the eastern region has the strongest willingness to change the structure of traditional agricultural elements input. The influence of non-agricultural income on the input of three agricultural elements is stronger than that of the central and western regions, and the substitution cost of agricultural machinery input is relatively low in the wheat-planting areas. The effect of non-agricultural income is stronger than that of planting rice or corn. The structural change of factor input is labor-saving, and the substitution cost of chemical fertilizer and pesticide input is lower than that of agricultural machinery input. The effect of non-agricultural income was more significant than that of planting wheat or corn, and the change of input structure was mainly land saving.
