基于处理效应的马铃薯种植户仓贮行为经济收益分析——以山东省五个马铃薯主产区为例

Economic Benefit Analysis of Potato Farmers Warehousing Behavior Based on Treatment Effect——Taking Five Potato Producing Areas in Shandong Province As Examples

2015年中国提出了马铃薯主粮化战略,使马铃薯成为继水稻、小麦、玉米之后的另一种主粮。研究旨在调查马铃薯种植户仓贮行为对其经济收益的影响,以山东省滕州、肥城、胶州、乐陵和邹城五个马铃薯主产区194个种植户的调研数据为例,利用处理效应模型进行实证研究。结果表明,马铃薯种植户的仓贮行为可以显著增加其收入,与不仓贮马铃薯种植户相比,仓贮马铃薯的种植户每公顷可增加39%的收入。基于此提出建立马铃薯仓贮补贴机制、进行农村仓贮点建设、加强马铃薯信息体系建设的建议,促进农户仓贮行为。

In 2015,China put forward the strategy of potato as the main food crop,making potato become another staple food crop after rice,wheat and corn.The purpose of this research was to investigate the impact of potato growers'warehousing behavior on their economic returns.Taking 194 potato growers'survey data from the five major potato producing areas of Tengzhou,Feicheng,Jiaozhou,Laoling and Zoucheng in Shandong Province as examples,this research used the treatment effect model to conduct an empirical study.The storage behavior of potato growers could significantly increase their income.Compared with the farmers who did not store potatoes,the farmers who stored potatoes could increase their income by 39%per hectare.Based on this,some suggestions are put forward,such as establishing potato storage subsidy mechanism,carrying out rural warehouse construction and strengthening potato information system construction,so as to promote farmers'warehousing behavior.
