【摘要】 基于山东省的数据分析表明:2002―2011年山东省生猪养殖正日益呈现规模化养殖趋势,在这个过程中,规模养殖户日增,其出栏的生猪占比越来越高。生猪养殖规模发展的动因主要是规模养殖具有信息优势,能降低交易费用,规模效应明显。生猪养殖规模化发展是养殖户主动发起或参与的逐利过程,但政府部门为加快生猪规模养殖发展,从多方面加强了对生猪规模化养殖的扶持。显然,扩大养殖规模的制度安排整体上优于生猪散养,可获得预期养殖效益,因此,养殖户偏好规模养殖。基于此,要进一步促进生猪养殖的规模化发展,应优化产业资源配置、发展新型养殖模式、推广先进养殖技术和明确政府引导方向等。更多还原

【Abstract】 Data analysis results in Shandong province indicate that hog breeding presents a large scale breeding trend over the ten years from 2002 to 2011.The number of scale-breeding households or farms has been increasing and the proportion of slaughter hogs has been raising in the process. The main reason hog breeding scale develops is information advantage, which could lower the transaction costs and gain the full economies of scale. Scale development is a process of hog-breeding households or farms pursuing interests and the government supports the large scale hog breeding in more ways. Obviously, the institution arrangement of scale-breeding is overall better than that of scatter-feed, and scale-breeding could achieve the expected benefits. Consequently, hog-breeding households or farms prefer large scale breeding. Based on that, the paper put forward strategies which include optimal resources allocations, new breeding mode development, and new technology application and government guidance.更多还原
