摘要:

针对兼业经营背景下我国蛋鸡养殖户生产效率异质性的问题，采用DEA-CLAD研究方法对兼业型蛋鸡养殖户的生产效率进行测算，并对其影响因素进行实证分析。结果表明： 1）忽视蛋鸡养殖农户的兼业经营活动会高估蛋鸡养殖户的技术效率和配置效率，低估其规模效率； 2）要素配置效率损失是我国蛋鸡规模养殖户效率损失的关键； 3）从区域角度，东北地区蛋鸡养殖农户的技术效率和配置效率最高，西部地区的技术效率、规模效率和配置效率都处于较低水平； 4）标准化养殖场，蛋鸡养殖户参加培训，户主受教育程度及养殖年限是影响蛋鸡养殖户技术效率的主要因素。

Abstract:

Aiming at the heterogeneity problem of laying hens breeding farmers' production efficiency under the background of concurrently industry management in China,DEA-CLAD model is used to calculate the production efficiencies of laying hens breeding farmers and take an empirical analysis is conducted to analysis their main influence factors.The results show that: 1) Neglecting the laying hen breeding farmers' concurrently industry management activities will overestimate the technical efficiency and allocative efficiency of laying hens breeding farmers and underestimate their scale efficiency; 2) The allocative efficiency loss is the key element of the efficiency loss of laying hens breeding farmers; 3) From regional view,the technical efficiency and allocative efficiency of laying hens breeding farmers in the northeast is the highest,and the technical efficiency,scale efficiency and allocative efficiency of the in western region are all low; 4) To standardize breeding,farmer's acceptance of training,education level and years of working experience in breeding are the main factors influencing the technical efficiency.Improving the allocative efficiency of the laying hens breeding farmers is important for the development promotion of laying hens industry in China.
