中文摘要：

已有的一些研究表明非农就业机会可能减少农户的农机投资,从而对农业生产带来负面影响.文章指出农户农机投资和服务利用的差别,在此基础上分析非农就业对农户农机服务使用量的影响.利用安徽农户调查数据进行实证分析的结果表明,非农就业增加以后,农户会增加农机服务的投入以替代减少的劳动.这与已有研究发现的非农就业与农户农机具等固定资产投资的负向关系形成了对照,说明农户的农机投资行为和服务利用行为存在差异,非农就业机会并未减少农机服务利用,因而未必对农业生产带来负面影响.

英文摘要：

The previous studies found that non-farm employment reduces farmers＇machinery investment and in-ferred a negative impact on agricultural output. In this paper we pointed out the difference between the input of machinery service and the investment of machinery. We empirically investigated the input behavior of machineryservice using the household data collected in Anhui Province. The results showed that farmers increase the inputof machinery service when they are more involved in non-farm employment. The positive relationship indicatedthat the input behavior is different from investment behavior for agricultural machinery and the agricultural outputmay not have been severely affected.
