中文摘要：

基于“大农机、大规模”视角，以位于我国粮食主产区黑龙江省的15个现代农机合作社为样本，通过调研获取大豆生产投入、产出数据，运用DEA模型分析黑龙江省现代农机合作社的大豆生产效率及其影响因素。结果表明：供试的15个样本中，2个样本是DEA有效的，样本有效率为13．3％；与种植多种作物的农机合作社相比，专业从事大豆种植的农机合作社生产效率更高；人力投入冗余与单位面积产出不足是影响非DEA有效样本纯技术效率的主要原因；合作社种植规模、管理水平和农业生产技术水平是生产效率的主要影响因素。根据分析结果，提出黑龙江省农机合作社应通过理论和经验的学习提升农业生产技术水平，适度扩大大豆种植规模，吸引更多农户参与规模化生产，通过提升纯技术效率和规模效率促进大豆生产的节本与增效。

英文摘要：

In this study, fifteen modem agricultural machinery cooperatives located in Heilongjiang Province, China＇ s major grain producing area, were selected as samples. Then the input and output data of soybean were obtained through investigation and the production efficiency as well as its influencing factors of soybeans produced by the fifteen modem agricultural machinery cooperatives in Heilongjiang province were analyzed by using DEA model The results showed that among fifteen samples, two samples were DEA effective and the effective rate was 13.3% ; compared with agricultural machinery cooperatives planting a variety of crops, the production efficiency of agricultural machinery cooperatives which were specialized in planting soybean was higher; redundant human input and insufficient unit area output were main reasons influencing pure technical efficiency of non-DEA effective samples ; main irfl＇luencing factors of production efficiency were planting scale, management level and agricultural production technical level of cooperatives. Based on the analysis results, suggestions were put forward that agricultural machinery cooperatives in Heilongjiang Province should enhance the study of theories and experience to raise the agricultural production technical level, properly expand the soybean planting scale to attract more farmers to take part in large-scale production and promote the cost saving and efficiency increase through raising pure technical efficiency and scale efficiency.
