中文摘要:采用Meta-frontier方法,将不同规模蛋鸡养殖户在共同生产前沿面下比较其近十年技术效率的变化。结果显示:2005-2015年,小规模养殖户的技术效率基本持平;中规模养殖户技术水平呈现出上升趋势,但技术效率仍存在短期波动,最终趋于更高的技术效率,这也说明这段时期我国小规模养殖户向中规模养殖户演进较为成熟;大规模养殖户技术效率也呈现出上升趋势,但仍较低,说明我国中规模蛋鸡养殖户向大规模养殖户演进处于初级阶段,仍有待进一步完善。

Dynamic changes of the technical efficiency in the evolution of layer culture scale in China: Based on Meta-Frontier method
Abstract:Meta-frontier method was adopted to measure and compare the egg farmers' technical efficiency of different scales under the common production frontier in the last ten years.The results showed that:In the past ten years,the technical efficiency of the small-scale farmers was in basic level;The medium-scale farmers increased investment in fixed assets,improved the technology level but decreased the technical exertion degree.It caused short-term fluctuations in technical efficiency and the farmers obtained higher level technical efficiency finally;the large-scale farmers improved the level of management and higher level of management influenced technical efficiency from the two aspects of technical efficiency.However,but the large-scale farmers technical efficiency was relatively low.In conclusion,the development of the middle-scale egg farmers is still in the initial stage and needs further improvement.
