| 中文摘要: |
| 基于辽宁省新民市一手调研数据，通过构建随机前沿生产函数模型，对3 个规模区间的玉米生
产技术效率进行测算，并对影响各规模区间玉米生产技术效率的外生因素进行实证分析，重点考察耕地细
碎化对不同规模区间农户玉米生产技术效率的影响。结果表明：（1）目前辽宁新民市不同规模平均玉米生
产技术效率在85% 以上，玉米生产技术效率随规模扩大呈先增加后减小趋势。（2）耕地细碎化对各个规模
区间技术效率影响存在较大差异。耕地细碎化对1.00 hm2 以下小规模农户影响不显著，对1.00～2.00 hm2 小
规模农户和2.00 hm2 以上大规模农户这两个区间均有正向影响。（2）年龄变量对小规模玉米种植户技术效
率有负向影响，受教育程度变量对大规模玉米种植户技术效率影响为正，受农业培训情况变量对大、中、小
3 个规模区间玉米种植户技术效率均有正向影响。 |
| 英文摘要: |
| Based on the survey data of Xinmin，Liaoning，this paper measured the technical efficiency of
corn production of three scale ranges，made empirical analysis on the exogenous factors influencing the technical
efficiency of corn production in different scale ranges and focused on the influences of land fragmentation on the
technical efficiency of corn production in different scale ranges by structuring SFA. The results showed that: the
average technical efficiency of corn production in different scale ranges in Xinmin，Liaoning was more than 85.00%，
and it firstly increased and then decreased as the scale enlarging. The influences of land fragmentation on technical
efficiency of different scale differed greatly. Land fragmentation had no obvious influence on the small-scale
households of being less than 1.00 hm2 and had positive influences on the medium-scale households ranging from 1.00 to 2.00 hm2 and the large-scale households of being more than 2.00 hm2. Commonly，farmer’s age affected negatively
on the technical efficiency of corn production of small-scale range，educational level affected positively on the
technical efficiency of corn production of large-scale range，and agricultural training status affected the three ranges
positively. |
