有机肥施用对农户利润的影响

Impact of organic fertilizer application on farmers’profit

探究有机肥施用的经济收益,对了解农户行为动机及技术推广具有重要作用。文中基于河南省476份农户数据,运用内生转换模型来研究有机肥施用的增收效应及作用路径,并从成本-收益角度来分析有机肥施用对农户利润的影响。结果表明:施用有机肥有助于提高粮食收入,能提升农产品收入3.17%-6.19%;农户施用有机肥通过改善农产品质量实现增收效应;从成本-收益情况分析,施用有机肥会使农户亩均利润增加60.70元,为验证利润准确性,运用PSM和对原区域二次调研的方法进行检验,得到结果均稳健。基于此,在推广与应用有机肥的同时,应加强建设绿色农产品市场和完善农产品质量检测认证制度,实现优质优价,给予绿色生产者补贴,以保障农户收益。

Exploring the economic benefits of organic fertilizer application plays an important role in understanding farmers’behavior motives and technology promotion.Based on 476 farmer’s data in Henan province,an endogenous conversion model was used to study the income increasing effect and action path of organic fertilizer application,and the impact of organic fertilizer application on farmers’profit was analyzed from the perspective of cost-benefit.The results showed that the application of organic fertilizer was helpful to increase income and increased the income of agricultural products by 3.17%-6.19%.The application of organic fertilizer by farmers improved the quality of agricultural products to achieve an increase in income.The cost-benefit analysis showed that the application of organic fertilizer increased the average income of farmers,the profit increased by RMB 60.70.In order to verify the accuracy of the profit,tests were conducted by PSM and the second investigation of the original area,and the results were all stable.According to the above results,it is suggested that while promoting and applying organic fertilizers,it is necessary to strengthen the construction of the green agricultural product market and improve the agricultural product quality inspection and certification system,to achieve high-quality and better prices,and subsidize green producers to guarantee the income of farmers.
