Analysis of influence of breeding scale on technical efficiency and scale efficiency——Taking laying chicken industry in Hebei Province as an example
To explore the path of moderate scale animal husbandry to promote high-quality development of the animal industry,and promote the steady development of large-scale and facility based animal husbandry in China,the article takes the laying hens industry in Hebei Province as an example,based on field research data,uses the data envelopment analysis(DEA)method to calculate the technical efficiency and scale efficiency of laying hens at different scales,and quantitatively analyzes the impact of breeding scale on technical efficiency and scale efficiency.The results show that the technical efficiency and scale efficiency of laying hens breeding in Hebei Province are at a high level.The breeding scale shows a U-shaped relationship with pure technical efficiency and an inverted U-shaped relationship with scale efficiency.The study indicates that it is necessary to avoid the loss of technical efficiency caused by redundant input factors,improve the structure and quality of agricultural resource input factors,attach importance to moderate scale management,and develop a modern laying hens breeding industry with high standards,scale,and specialization.
