农村劳动力流转、粮食商品化程度对粮食主产区农户的农机购置行为的影响分析——基于全国587户粮农数据

利用全国587户粮农数据，通过单因素相对影响比率与Logit模型研究了粮食种植户农机购置行为的影响因素。研究结果表明，外出劳动力数与粮食收入比重对农户购置农机具具有显著的负向激励；粮食生产商品化程度以及粮食直补政策对农户购置农机具有显著的正向激励；耕地面积越大、耕地细碎化程度越低则农户购置农机具的倾向越强；粮食主产区农户的农机购置程度显著较高，而粮食主销区则显著较低；小麦种植户的农机购置程度显著较高，而水稻种植户则显著较低。

The Impact Analysis of Rural Labor Migration and Grain Commercialization on Agricultural Machinery Purchase in Major Grain Producing Areas --Based on 587 Farmers Data around the Country

Based on data obtained from 587 grain farmers＂ families around the country, and employing the single factor＂ relative influence ratio and the Logit model, this paper analyzed the influencing factors which take effects on grain farmers＂ agricultural machinery purchase. The results show that, the outflow labor population and the non-grain revenue proportion have a significant negative incentive to agricultural machinery purchase; the grain commercialization and grain subsidy policy has a significant positive incentive to agricultural machinery purchase ; greater land scale and lower degree of land fragmentation promote stronger inclinations toward agricultural machinery purchase; in main grain producing areas, the degree of agricultural machinery purchase is significantly higher, and it is lower in main grain sale areas; compared with the rice farmers, the degree of agricultural machinery purchase of the wheat farmers is significantly higher.
