中文摘要：

为研究规模化经营耕地集约度的特征及影响因素,运用熵值法及计量估计模型,以马铃薯为例,分析内蒙古农牧交错带普通农户与种植大户的耕地集约度及影响因素。结果表明：种植大户在耕地的投入水平、产出水平都显著高于普通农户,但在耕地的可持续利用水平上显著低于普通农户,总体耕地集约利用水平是后者的4.84倍。影响种植大户耕地集约度的生计因素主要有户主年龄（负相关）及家庭贷款金额（正相关）。影响普通农户耕地集约利用程度的因素主要有家庭年收入（正相关）、家庭畜牧业收入（负相关）、家庭贷款金额（正相关）。

英文摘要：

Taking Ulanqab City as an example,the intensity attribute and influence influential factors of scale arable management of potato planting ordinary households and potato planting scale households land were investigated by using mathematical statistics methods.The results showed that the scale households were significantly higher in input and output levels than those of the ordinary households,but was significantly lower in cultivated land＇s sustainable utilization level than that of the ordinary households.On the whole,the intensity degree of cultivated land of the scale households was 4.84 times of the ordinary households.Main factors affecting the scale households cultivated land intensity degree included household age（negative correlation）and home loan amount（positive correlation）.Main factors influencing the ordinary farmers cultivated land intensive degree included annual household income（positive correlation）,family farming income（negative correlation）and loan amount（positive correlation）.
