农田宜机化水平如何影响农机服务供给?

How the Farmland Suitability for Agricultural Machinery Operations Affects the Supply of Agricultural Machinery Services

基于全国100个丘陵山区县4074份农机户的样本数据,考察了农田宜机化水平对农机户农机服务供给行为的影响及作用机制。研究发现:农田宜机化水平能够提升农机户农机服务供给概率与服务供给水平,且对农机户农机服务供给水平的影响在服务供给环节数与服务供给面积两方面均显著为正。机制分析发现,农田宜机化水平通过扩大农机服务市场规模,进而提高农机户的农机服务供给概率与环节数,通过提升农机的作业效率,进而增加农机户的农机服务供给面积。异质性分析发现,农田宜机化水平提升对青壮年农机户农机服务供给的促进作用大于中年农机户,对老年农机户农机服务供给水平以及经营规模小于50亩的农机户农机服务供给环节数的影响不显著。

Based on sample data from 4074 agricultural machinery households in 100 hilly counties across of China,this study examines the impact and mechanisms of farmland suitability for agricultural machinery operations(FSAM)on the supply behavior of agricultural machinery services by agricultural machinery households.The research finds that the level of FSAM can increase both the probability and the level of agricultural machinery service supply by agricultural machinery households.The positive impact on service supply level is significant in terms of both the number of service supply links and service supply area.Mechanism analysis reveals that the level of FSAM enhances the agricultural machinery service supply probability and number of agricultural machinery service supply links of agricultural machinery households by expanding the market size for agricultural machinery service,and increases the service supply area by improving the operational efficiency of agricultural machinery.Heterogeneity analysis indicates that the promotion effect of FSAM on the agricultural machinery service supply by young and middle-aged agricultural machinery households is greater than that on middle-aged households.The impact on the service supply level of elderly agricultural machinery and the number of service supply links for households with an operating scale of less than 50 mu is not significant.
