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

Impact of Grain Specific Income Subsidy on Grain Production Technology Efficiency:Take Rice Planting of Different Scales as an Example

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。

This paper firstly analyzed the effect of grain specific income subsidy on grain production technology efficiency.Then it used the micro-farm household survey data collected by Jiangsu Provincial Price Bureau from 2012 to 2017,and with rice as an example,empirically analyzed the effect of rice-specific income subsidy on rice planting technical efficiency of different scales.The results show that:Firstly,the average technical efficiency of rice planting in Jiangsu is 0.927,a relatively high level.In terms of time,the technology efficiency of rice planting in Jiangsu has slightly decreased.In terms of space,the technology efficiency of rice planting shows a trend of successive decline in northern Jiangsu,central Jiangsu and southern Jiangsu.Secondly,there exist significant scale differences in the effect of rice specific income subsidy on the rice production technology efficiency.In(0,0.20)hm^2 and(0.67,+∞)hm2,the rice-specific income subsidy has no significant effect on technical efficiency,while in(0.20,0.33)hm2 and(0.33,0.67)hm^2,the subsidy has played a significant role in promoting technical efficiency.Finally,relevant suggestions were put forward to promote the implementation of the grain-specific income subsidy policy.
