| Abstract: |
| To analyse the situation of laying hens breeding efficiency based on cost minimization in China.
We collected panel datas from National Agricultural Product Cost and Income Data Compilation（2005-2015）.
We divided datas by scale in large，medium and small. We used the stochastic frontier method（SFA）to calcucate
cost efficiency of laying hens in China. The results of empirical analysis show that the cost efficiency of small scale
breeding hens is high，but the cost efficiency of large and medium scale in all provinces is low. The results also show
that cost efficiency of small scale breeding hens is creasing over time，while the large and medium scale’s are
decline，and the gap of cost efficiency between large and medium scale is obvious. We also find that sales price has
a negative impact on cost efficiency. Based on results above，we suggests that it is important to focus on the large and
medium scale laying hens. At the meantime，it is necessary to focus on strengthening the technical promotion and the
specialization of the medium scale. |
