【摘要】土地细碎化一般被视为阻碍农业机械化发展的重要因素, 而随着农业技术进步和经济发展, 土地细碎化对农业机械化的影响越发复杂。本文使用2015年农户微观调查数据, 利用参数和半参数方法分析了土地细碎化对甘蔗种植机械化的影响。研究结果表明:总体上, 土地细碎化对甘蔗种植机械化具有负向影响, 但只有在土地细碎化程度较高时这种影响才较为显著;土地细碎化对部分机械化种植方式不具有阻碍作用;不同土地细碎化程度对机械化种植方式的影响存在差异;农户平均地块面积在5~10亩之间时, 平地地块所占比重和农业劳动力比重是造成全程机械化种植方式与其他种植方式有所区别的重要因素。本文研究结论说明, 中国在甘蔗种植中应结合土地细碎化的特点, 配套不同机型, 发展多样化的甘蔗机械化种植方式, 以实现资源的优化配置。

【Abstract】Land fragmentation has generally been regarded as a substantial factor to affect agricultural mechanization. With technical progress in agriculture, however, the relationships between land fragmentation and agricultural mechanization become more complicated. This article uses micro-survey data in 2015 and parameter and semi-parameter models to study the effects of land fragmentation on sugarcane planting mechanization. The results overall indicate a negative correlation between land fragmentation and mechanization of sugarcane cultivation, and this correlation becomes significant when the degree of land fragmentation is high. On some patterns of production mechanization, however, no hindering effect can be found. Besides, different degrees of land fragmentation imply different effects on the patterns of planting mechanization. Furthermore, the proportions of the average parcel area and agricultural labor force are found to be important factors inducing the differences in the patterns of production mechanization when the average parcel area ranges from 5 mu to 10 mu. Finally, the study suggests that, in order to achieve the optimal allocation of resources, the characteristics of land fragmentation should be taken into consideration in the development of a variety of patterns of sugarcane production mechanization with different types of machines.
