【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.
