农业技术采用、时间重配置与农户收入

Agricultural Technology Adoption,Time Reallocation and Farmer’s Income

在构建农业技术采用影响农户时间再配置理论框架的基础上,利用2015-2017年河北、山东、辽宁等蔬菜主产区农户调研数据,联合运用内生转换模型和多重中介效应模型,定量验证了滴灌采用对农户收入的影响,以及时间重配置产生的中介作用,包括雇工效应、溢价效应、转移效应和产量效应。结果表明:蔬菜种植农户采用滴灌后收入显著提高,主要机制是产量效应和溢价效应,表现为年产量增加9212.83千克、溢价销售比例提高18.89%,分别对应的户均年收入增幅为1842.80元和1354.75元,中介效应占总效应的61.97%。因此,在推广农业技术促进农户收入增加时,创造和改善农户时间重配置的环境和能力,可有效保证收入增加的主动性和持续性。

Based on the investigation data of farmers in Hebei,Shandong,Liaoning and other major vegetable producing areas between 2015 and 2017,this paper constructs the theoretical framework of agricultural technology adoption affecting farmers’time reallocation by using endogenous transformation model and multiple mediating effects model.It quantitatively verifies the impact of adoption of drip irrigation on farmers’income,as well as the mediating effects of time reallocation,including the employment effect,the premium effect,the transferring effect and the yield effect.The results show that the income of vegetable farmers increase significantly after adopting drip irrigation because of the yield effect and premium effect.The annual vegetable yield increases by 9212.83kg and the percentage of premium sales increases by 18.89%,and the corresponding contribution to average annual income of the farmer household are￥1842.80 and￥1354.75.As a whole,the mediating effects account for 61.97%of the total effect.Therefore,in the process of developing agricultural technology to increase farmers’income,creating conditions for farmers’time reallocation and improving farmers’ability to reallocate time can effectively ensure the initiative and sustainability of income increasing.
