摘　　要：为探究“服务规模化”与“土地规模化”二者间的关系,以及进一步明晰我国农业规模化发展方向与路径。基于全国省级层面2000—2016年期间的面板数据,从不同土地规模的视角,分析农机服务对粮食生产技术效率的影响。研究结果表明:农机服务对粮食生产技术效率有显著的正向影响,其中,农机服务1的影响系数为0.0501,农机服务2的影响系数为0.0339。此外,农机服务对粮食生产技术效率影响程度与农户的土地规模呈正比,在大规模区域,农机服务1和农机服务2的影响系数分别为0.0619、0.0459,在小规模区域,对应的影响系数分别是0.0587、0.0278,说明农机服务对粮食生产技术效率的影响会受限于土地规模大小。由此可以得出,“服务规模化”并不能完全的替代“土地规模化”,反而,土地规模会反过来影响农机服务的作用效果。由此可以得到的政策启示是,在积极推进我国农机服务发展的同时,也应注重推动土地规模化进程,避免过分强调服务规模化进而走向另一种极端的倾向。In order to explore the relationship between“service scale”and“land scale”,the direction and path of China's agricultural scale development should be further clarified.Based on panel data at the provincial level from 2000 to 2016,the impact of agricultural machinery services on the technical efficiency of grain production from the perspective of different land sizes was analyzed.The research results showed that agricultural machinery service had a significant positive impact on the efficiency of grain production technology.The impact coefficient of agricultural machinery service 1 was 0.0501,and the impact coefficient of agricultural machinery service 2 was 0.0339.In addition,the impact of agricultural machinery services on the efficiency of food production technology was directly proportional to the land sizes of farmers.In large-scale areas,the impact coefficients of agricultural machinery service 1 and agricultural machinery service 2 were 0.0619 and 0.0459,and in small-scale areas,the corresponding impact coefficients were 0.0587 and 0.0278.It showed that the impact of agricultural machinery services on the technical efficiency of food production would be limited by the size of the land.It was concluded that“scale of service”cannot completely replace“scale of land”.On the contrary,the scale of land will affect agricultural machinery services.The policy enlightenment that can be concluded is that while actively promoting the development of agricultural machinery services in China,it is also necessary to promote the scale of land,avoid excessive emphasis on the scale of services.
