中国生猪规模增长与养殖技术变化的实证研究

以2006—2010年度中国生猪主要养殖省(市、自治区)的面板数据为基础,利用Cobb-Douglas生产函数,对中国生猪规模增长与养殖技术的关系进行了实证研究。结果表明养殖规模越小越不利于技术进步,表现在散户和小规模养殖技术未发生显著性改变,而中规模和大规模的养殖技术却发生显著性的变化。提出了在政策上加大散户和小规模养殖户的整合,增强对大中规模的技术支持和政策扶持力度的建议。

Empirical Study on Relationship between Scale Growth and Technology Changes of Pig Breeding in China

Based on the panel data of China＇s main breeding pig provinces （municipalities,autono- mous regions） from 2006 to 2010, this paper makes the empirical study on the relationship between scale growth and technology changes of pig breeding in China by using Cobb-Douglas production function. The result shows that the smaller the scale of pig breeding is,the less progress the breeding technology will make,which means that breeding technology does not make significant changes in the retail and smallscale pig breeding, while breeding technology shows significant changes in the medium scale and the large scale breeding. Therefore,this paper proposes some suggestions on how to integrate the retail and small-scale pig breeding farmers as far as the policy is concerned and increase the technical support and policy support for large and medium size pig breeding farmers.
