【摘要】：基于成本最小化的假设,利用随机前沿成本函数对我国蛋鸡养殖业2004—2014年的成本效率进行测算,结果表明,小、中、大规模成本效率分别为0.847、0.863和0.866,存在一定的效率损失,近11年来效率值呈现先升后降的倒"U"形变化趋势。进一步分析成本非效率影响因素发现,料蛋比、疾病防疫、产业结构对成本非效率具有显著正效应;从养殖户的角度进一步分析发现,专业户较非专业户具有更高的成本效率。此外,养殖规模差异并非导致成本效率差异的直接原因。
[Abstract]:Based on the hypothesis of cost minimization, the cost efficiency of the poultry breeding industry in China from 2004 to 2014 was calculated by using the random frontier cost function. The results showed that the small, medium, large-scale cost efficiency was 0.847,0.863 and 0.866 respectively, and there was a certain amount of efficiency loss. In the last 11 years, the rate of efficiency showed an upside down "U" change trend. The factors that affect the cost inefficiency show that the ratio of material and egg, disease prevention and industrial structure have significant positive effect on the cost inefficiency. From the point of view of the farmers, it is found that the professional households have higher cost efficiency than non professional households. In addition, the difference in scale of culture is not the direct cause of the difference of cost efficiency.
