【摘要】 针对近年来我国牛肉产量供不应求的市场现状，为提高肉牛养殖生产效率提供实证参考依据，对吉林省7个地级市内223户养殖户进行问卷调查，选用DEA-Tobit模型对吉林省大、中、小三种肉牛养殖规模的生产效率进行测算评价，并对影响生产效率的因素进行实证分析。结果表明：当前吉林省肉牛养殖整体综合效率还存在进一步提升的空间，在现有生产技术条件下，三种不同规模肉牛养殖的生产效率均值为中规模优于大规模优于小规模。不同规模肉牛养殖生产效率之间存在差异，且影响不同规模肉牛养殖生产效率的因素及程度不同。更多还原

【Abstract】 In view of the market status of that the beef production cannot meet the demand, and to improve the production efficiency of beef cattle breeding, a questionnaire survey was conducted among 223 farmers in seven prefecture-level cities of Jilin Province. DEA Tobit model was used to evaluate the production efficiency of large, medium and small beef cattle breeding scale in Jilin Province, and the factors affecting the production efficiency were analyzed. The results showed that at present, there is still room for further improving the overall efficiency of beef cattle breeding in Jilin Province. Under the existing production technology conditions, the average production efficiency of three different scales of beef cattle breeding is that medium scale is superior than large scale and small scale. The results showed that there is difference in the production efficiency of beef cattle breeding of different scales, and the factors and degrees that affected the production efficiency of beef cattle breeding of different scale are different.更多还原
