我国农牧户肉羊生产配置效率及影响因素分析

Allocation efficiency of farmers' meat sheep production in China and its influencing factors

首先采用DEA成本效率模型对中国7省区20个县(市、旗)的200户农牧户肉羊生产配置效率进行测算,然后利用Tobit模型对肉羊生产配置效率的影响因素作进一步分析。结果表明:2014年调研地区农牧户肉羊生产配置效率的平均值为62.27%,存在一定的配置效率损失;农区肉羊生产的配置效率为0.7148,高于牧区和半农半牧区;户主年龄、户主受教育程度、是否参加合作社、协会等组织、是否接受过养殖技术培训以及是否获得过政府扶持对农牧户肉羊生产配置效率均具有显著的正向影响;是否借贷过资金对农牧户肉羊生产配置效率具有显著负向影响;在其他条件不变的情况下,舍饲、半舍饲的肉羊生产配置效率要显著低于采用放养方式肉羊生产的农牧户;与农区相比,牧区、半农半牧区农牧户肉羊生产的配置效率水平相对较低。

Based on survey data of 200 meat sheep-raisers belonging to 20 countries of seven provinces in China,we applied DEA cost efficiency model and Tobit model to assess the allocation efficiency of farmers＇ meat sheep production and its determines. Results indicated that the mean allocation efficiency of farmers＇ meat sheep production in 2014 was 62. 27%,existing a certain loss efficiency. Agricultural areas＇ allocation efficiency of meat sheep production was 0. 7148,higher than the pastoral and semi pastoral areas. Determinants of allocation efficiency such as householder age,education level,whether participated in cooperatives or associations,training experience and government support were found to be positive and significantly related to allocation efficiency. Although whether loaned funds had a significant negative impact. In the case of other conditions unchanged,feeding,semi feeding allocation efficiency of meat sheep production was significantly lower than the stocking of farm households. Compared with the agricultural areas,the allocation efficiency level of the meat sheep production in the pastoral areas,semi-agricultural and semi-pastoral areas was relatively low.
