英文文献摘要:
Off-farm income has recently been incorporated into the analysis of technology adoption, due to its increasing share in total farm household income in the U.S. Previous studies, however, found inconsistent results with respect to the impact of off-farm income on adoption of conservation practices. The contribution of the current study is to provide a conceptual model which shows that off-farm work has positive impact on adoption of capital incentive practices and negative impact on adoption labor intensive technologies. The results of multivariate probit regression confirms that adoption of injecting manure into the soil, which is a capital intensive practice, is positively and significantly impacted by off-farm work, and adoption of record keeping, which is a labor intensive practice, is negatively and significantly impacted by off-farm work.
由于非农收入在美国农业家庭总收入中所占比例不断上升,非农收入最近被纳入了对技术采用的分析。然而,之前的研究发现,关于非农收入对保护措施采用的影响,结果并不一致。本研究的贡献在于提供了一个概念模型,表明非农工作对资本激励措施的采用有积极影响,而对劳动密集型技术的采用有消极影响。多变量probit回归结果证实,非农工作对资本密集型的土壤注粪方式产生显著正影响,对劳动密集型的土壤保本方式产生显著负影响。
