Abstract: Farmland use right transfer between households is essential to the agricultural modernization and national food security and has aroused a wide concern. This article takes Taipusiqi County, Inner Mongolia as an example of agro-pastoral interlaced region, and uses binary logistic model to analyze the driving factors of farmland land transfer due to differences between farmers. Result showed that nearly half of the households in Taipusiqi County transfered in or out cultivated land. Households with more on-farm labors, more agricultural machinery, higher proportion of farming income and husbandry income, were more likely to transfer in farmland, and had much less possibility to transfer out their cultivated land. Because of substitution effect of machinery to labor, off-farm employment promoted farmers to transfer in land. Older farmers were reluctant to expand their farming acreage, while because of the stronger dependence on the land, older farmers also were reluctant to transfer out of their farmland. Educated level and cultivated area per labor had no significant effects on land transfer. So, the implementation of the policy to increase more subsidies for agricultural machinery is significant to promote land use right transfer and large-scale agriculture.
