Although scholars have elaborated on the effects of aging, there is no consensus on the relationship between the aging and farmers' pesticide input. Regional differences in agricultural crops in China, namely 'Southern Rice and Northern Wheat', have not been considered in any of the existing studies.
Based on the data of 443 wheat farmers and 324 rice farmers in China, this study found that aging significantly increased pesticide input. After sorting out the types of pesticides, it was found that the aging significantly increased the input of biological pesticides, but did not affect the input of chemical pesticides. After considering the planting pattern of 'Southern Rice and Northern Wheat', aging did not have a significant impact on the pesticide input of wheat farmers, but had a significant positive impact on the pesticide input of rice farmers. For wheat farmers in the north, social services have a significant inhibitory effect on the relationship between aging and pesticide input. For rice farmers, path dependence has a significant role in promoting the relationship between aging and pesticide input.
The planting pattern of 'Southern Rice and Northern Wheat' will indeed affect the relationship between aging and pesticide input, and social services and path dependence are the main reasons for this heterogeneity effect. Therefore, improving agricultural socialization services and reducing farmers' dependence on traditional production experience will be an important way to effectively reduce the impact of aging. © 2023 Society of Chemical Industry.
尽管学者们已经详细阐述了老龄化的影响,但对于老龄化与农民农药投入之间的关系尚无共识。中国农业作物的地域差异,即“南稻北麦”,在现有的研究中都没有考虑到。
基于中国 443 位小麦种植户和 324 位水稻种植户的数据,本研究发现老龄化显著增加了农药投入。在梳理了农药的种类后,发现老龄化显著增加了生物农药的投入,但对化学农药的投入没有影响。在考虑了“南稻北麦”的种植模式后,老龄化对北方小麦种植户的农药投入没有显著影响,但对南方水稻种植户的农药投入有显著的正向影响。对于北方的小麦种植户来说,社会服务对老龄化和农药投入之间的关系有显著的抑制作用。对于水稻种植户来说,路径依赖在促进老龄化和农药投入之间的关系方面起着重要作用。
“南稻北麦”的种植模式确实会影响老龄化和农药投入之间的关系,社会服务和路径依赖是这种异质性效应的主要原因。因此,提高农业社会化服务水平,减少农民对传统生产经验的依赖,将是有效降低老龄化影响的重要途径。© 2023 英国化学工程师学会。
