粮食收入性补贴对粮食生产技术效率的影响分析——以不同规模稻谷种植为例

利用2012—2017年江苏省物价局调研的微观农户数据,以三大主粮之首的稻谷为例,实证分析稻谷种植收入性补贴对不同规模农户稻谷种植技术效率的影响。结果表明:(1)江苏稻谷种植技术效率的均值为0.927,处在相对较高水平;在时间上,江苏稻谷种植技术效率出现略微下降的趋势;在空间上,江苏稻谷种植技术效率呈现出苏北、苏中、苏南依次递减的趋势。(2)稻谷种植收入性补贴对稻谷种植技术效率的影响存在明显的规模差异。在(0,0.20)hm^2和(0.67,+∞)hm^2上,稻谷种植收入性补贴对技术效率的影响不显著,而在(0.20,0.33)hm^2和(0.33,0.67)hm^2上,稻谷种植收入性补贴对技术效率具有显著的促进作用。最后,提出相关建议以促进粮食收入性补贴政策更好的实施。
