【摘要】 基于内蒙古草原牧区的微观调研数据，构建多元回归模型分析参与草场转入行为的牧户与未参与草场流转行为的牧户之间的成本差异，探讨通过草场流转而扩大草场经营面积的牧户能否有效减少草料支出、降低生产成本以及实现规模经济。研究发现：牧户转入草场后草料支出显著减少，单位饲养成本显著降低，转入草场扩大经营面积可以实现规模经济，转入草场对草场生产力较高的牧业旗效果更突出。因此，鼓励牧区草场合理流转，特别是草场生产力较高地区，发展适度规模经营，提高经济效率，促进牧民增收。更多还原

【Abstract】 Based on the micro research data of pastoral areas in Inner Mongolia, a multiple regression model was built to analyze the differences in the production cost of animal husbandry between herdsmen who leased grassland and those not participating in grassland circulation. Whether the expansion of grassland operation area through leasing could effectively reduce forage expenditure, lower production and operation cost,and realize the scale economy was discussed. The study found that the forage expenditure and the cost of feeding per head significantly reduced after grassland leasing. Meanwhile, expanding pasture area through grassland leasing could achieve scale economy. The effect of grassland circulation was more prominent in pastoral regions with higher grassland productivity. Therefore, encourage rational grassland circulation in pastoral areas, especially in areas with high grassland productivity, develop moderate scale management,thereby improving production and economic efficiency, and promoting income growth for herdsmen.更多还原
