规模农户病虫害防治机械投资及其效应

Investment in Pest Control Machinery of Large-scale Farmers and Its Effect

利用江苏省水稻产业体系对规模种植户的调研数据,使用Heckman样本选择模型,从作业质量风险认知和作业及时性风险认知角度出发分析病虫害防治环节影响规模种植户机械投资和投资水平的原因,并进行稳健性检验,在此基础上分析投资机械自给服务对农户农业产出的影响。研究发现:规模种植户是否进行机械投资以及投资水平不仅受外包服务作业质量风险认知的影响,农户对于外包服务作业的及时性风险认知也是影响其机械投资的关键,并且农户的风险规避程度在风险认知影响病虫害防治机械投资决策之间具有显著的调节作用。进一步分析发现,规模农户投资病虫害机械自我防治可以显著提升农业产出水平。

This paper uses the survey data of large-scale farmers in the rice industry system in Jiangsu Province,and uses the Heckman sample selection model to analyze the reasons for the impact of pest control on machinery investment and investment level of large-scale farmers from the perspectives of risk perception of operation quality and operation timeliness and conduct a robustness test. On this basis,the impact of investing in machinery self-sufficiency services on the agricultural output of farmers is further analyzed. It is found that large-scale farmers’ willingness to invest in machinery and the level of investment are affected not only by the farmers’ quality risk perception of outsourcing service operations,but also by the farmers’ timeliness risk perception of outsourcing service operations,and the degree of risk aversion of farmers plays a significant regulatory role in the impact of risk perception on investment in pest control machinery. Further research shows that large-scale farmers’ investment in pest control machinery can significantly improve agricultural output.
