摘要
当前我国农户兼业现象十分普遍。本文基于在内蒙古太仆寺旗的农户调查数据,采用单因素方差分析法,对生态脆弱区农户兼业及其对耕地利用的影响进行了研究。结果表明:当前研究区农业劳动力非农就业和农户兼业现象十分突出,而兼业程度不同的农户,其经营土地的方式差异明显。非农就业户通过将其土地转给其他农户而脱离了农业耕作,这同时满足了其他农户扩大土地经营面积的愿望。种植结构差异不大,均体现为劳动生产率高的作物具有优势;对于有耕地利用行为的纯农业户、I兼型农户和II兼型农户,随着兼业程度的增加,物质投入增加,说明农户兼业使其资金约束减小,增加了资金投入能力,但是在劳动力约束下,兼业农户的劳动力投入减少,且务农劳动力"妇女化"、"老龄化"和"文化低"等现象突出;作物单产和土地净收益纯农业户大于兼业农户,说明劳动投入对土地产出更为重要。文章最后认为建立农业劳动力非农就业与耕地利用相互协调的机制,是解决生态脆弱区生态安全与农业生产之间矛盾的重要途径。
