Abstract农户小规模的农业生产方式已经与我国农业现代化的发展产生冲突,在全国大力推进土地流转和发展农业适度规模经营的背景下,对种植规模与规模效率之间关系的研究就成为了热点。本文利用368份江汉平原水稻种植农户的调查数据,应用"DEA-OLS"两阶段分析方法,对水稻种植的规模效率进行了测算,并考察了种植规模与规模效率之间的关系。结果表明:(1)江汉平原内农户水稻种植的规模普遍较小,平均为0.77公顷,规模效率平均为0.88,规模效率是限制水稻种植综合技术效率增加的主要因素,有88.32%的农户都处在规模报酬递增的阶段。(2)水稻种植规模与规模效率之间确实存在稳定的倒"U"型关系,在考虑户主特征、土地质量和家庭特征的情况下,农户水稻种植规模达到5公顷时,规模效率最大。(3)户主特征因素中,户主年龄对规模效率有显著的负向影响;户主从事非农工作的家庭比户主纯务农的家庭规模效率低。耕地质量因素中,地块的灌溉条件对规模效率有显著的正向影响。家庭特征因素中,使用机械播种的家庭比手工播种家庭的规模效率高3.07%。因此,我们建议当地政府积极推进土地流转,实行阶梯式的规模经营补贴,增加在灌溉条件改善和机械设施普及上的投入,以鼓励农户扩大种植规模,提高规模效率和种植收益,发展适度规模经营。
