经营规模受限情况下的农机选型方法研究

Agricultural Machinery Selection Method Research When the Land Scare is Limited

通过计算一定土地规模条件下运用某农业机械的经济成本,作为机具选型的依据。并探索随着土地经营规模的改变,机具选型结果的变化规律。研究发现,一般情况下,土地规模较小时,作业效率低但价格很便宜的机型经济成本较低;土地经营规模较大时,价格较贵但作业效率很高的机型逐渐占据优势。因此,当现实中农业生产经营者的土地规模较小时,可以选择购买价格较低但可靠性相对较好的国产农业机械,而不是盲目地跟风购买经济成本很高的进口农业机械。

In this paper, we evaluate a kind of agriculture machinery by calculate the cost of using it in the case of a certain scare. We also tried to find regular rule of the chosen when the land scare is changed. We find that, if the land scare is small, it＇ s better to choose a cheap machine even it＇ s efficiency is lower; if the land scare is large, it＇ s better to choose a machine with a high efficiency even it is more expensive. So, if the land scare is small, the operator can buy a kind of domestic agricultural machine with a cheaper price but better re- liability, instead of buying import machine with high costs.
