摘要: |
基于3省521户农户问卷调查数据,利用内生转换回归模型(ESR)实证分析农业病虫害防治外包对农户家庭收入及收入结构的影响,并进一步探讨群组差异。研究发现:(1)农业病虫害防治外包有助于农户增收。在反事实假设下,选择农业病虫害防治外包的农户若未选择外包,其家庭年人均收入和家庭年人均工资性收入将分别下降8.7%和9.9%。(2)从群组差异来看,农业病虫害防治外包对工资性收入占比较低和耕地面积较大农户的增收效应更明显。 |

Abstract: |
Based on the questionnaire data of 521 farmers in three provinces, this paper uses the endogenous transformation regression model (ESR) to analyze the impact of agricultural pest control outsourcing on household income and income structure, and further discusses the effect on different groups of farmers.The results are as follows:(1)The outsourcing of agricultural pest control can help farmers increase their income. Under the counterfactual assumption, if the farmers who actually choose the outsourcing of agricultural pest control do not choose the outsourcing of agricultural pest control, the annual per capita income of the family and the annual per capita wage income of the family will decrease by 8.7% and 9.9% respectively.(2)From the perspective of different groups of farmers, outsourcing of agricultural pest control has significant income effect toward the farmers who have low wage income proportion and large cultivated land area. |
