价格传递非对称性使猪肉价格不能有效反映市场供求，扭曲了养猪业市场资源配置，是引起我国猪肉价格周期性大幅度波动的主要原因。以纵向市场结构理论和价格形成机制为基础，对比分析了纵向分离市场结构和一体化市场结构下的猪肉价格、猪肉销售量和纵向产业链整体利润情况。结果表明，信息不对称导致的逆向压价效应，不但扭曲了生猪市场价格、降低生猪养殖者利润，也误导了生猪养殖行为；数量众多的生猪散养户、可维持信息不对称和过多纵向关联环节是导致猪肉价格传递非对称的内在原因。因此，扩大生猪养殖规模和减少纵向关联环节数量是打破信息不对称、价格传递非对称性和促进养猪业健康发展的根本措施。

Pork prices can not effectively reflect the information of supply and demand for asymmetric price transmission ,which distorts the resource allocation of the pig industry market and is the main reason of cyclical fluctuations in pork prices .This paper discusses the causes of asymmetry price transmission ,economic entities’asymmetric information and the characteristics of vertical pork markets .The mechanism of asymmetric price transmission is generated the intrinsic existence of information asymmetry .Therefore,expanding the scale of pig farming and reducing associated links are the key to breaking the longitudinally asymmetric information , asymmetry price transmission and promoting the healthy development of the pig industry .
