| 摘要: |
| 为了解动物疫病净化与养殖场生产效率之间的关系，使用全国297个规模化养鸡场2011—2015年的调查数据，通过构建超越对数形式的生产函数模型以及技术损失函数模型，探讨疫病净化对养鸡场生产技术效率的影响。结果表明：养鸡场开展鸡白痢以及其它疫病的净化，可有效提高其生产技术效率。具体来看，疫病净化对蛋鸡场的生产技术效率产生了一定的影响，但不显著，对肉鸡场的生产技术效率产生显著影响。分地区来看，开展鸡白痢净化显著提高了华北地区、华南地区以及东北地区养鸡场的生产技术效率，开展禽白血病净化显著提高了华东地区和西北地区养鸡场的生产技术效率，开展其它疫病净化尚未提高各个区域养鸡场的生产技术效率。据此，建议国家强化对疫病净化政策的宣传，鼓励更多的养殖场（户）积极开展此项工作。充分发挥市场作用，引导养殖场有序、合理地进行疫病净化，以此实现净化16种主要疫病的目标。 |

| Abstract: |
| In order to understand the relationship between animal disease purification and the production efficiency of farms,this study collected the survey data of 297 large-scale chicken farms in China from 2011 to 2015.A beyond logarithmic production function model and a technology loss function model were constructed to explore the impact of disease purification on the production technical efficiency of chicken farms.The results indicated that the purification of pullorum disease and other diseases effectively improve the production technology efficiency.Specifically,the disease purification had some effects on the production technical efficiency in layer farm,but not obvious and displayed a significant impact on the production technical efficiency in broiler farm.From a regional viewpoint,the purification of pullorum disease improved the production technology efficiency of chicken farms in North China,South China,and Northeast China significantly,and the purification of avian leukosis improved the production technology efficiency of chicken farms in East China and Northwest China significantly,and the purification of other diseases did not improve the production and technical efficiency of chicken farms in various regions significantly.In conclusion,to achieve the goal of purifying 16 major diseases it was recommended that the state should strengthen the promotion of the disease purification policy and encourage more farms (households) to actively carry out this work,give full play to the role of the market,and guide the farms to carry out disease purification orderly and gradually. |
