摘要
将养猪业视作一个由饲料产业,仔猪饲养,生猪养殖屠宰以及猪肉的销售等环节构成的产业链,把养猪业上中下游产品定义为玉米,仔猪,生猪,猪肉,即玉米价格和仔猪价格为养猪业上游产品价格,生猪价格为养猪业中游产品价格,猪肉价格为养猪业下游产品价格。从价格变异率的角度,重点研究了养猪业上中下游产品价格波动幅度的变化规律,探究了影响养猪产业链价格稳定的重要产品。通过对2000～2009十年间的养猪业上中下游产品价格的统计描述分析、价格波动测度分析得出了影响养猪业价格稳定的关键因素,即仔猪和生猪价格。
In this article,the pig industry include some links as a industry chain which is the feed industry,piglets feeding,pig cultivation and pork sales.The pig industry is defined as upstream products-corn and piglets,middle stream products-pigs and down stream products-pork which means that the price of upstream is the price of corn and piglets,the price of middle-stream products is the price of pigs and the price of downstream products is the price of pork.From the perspective of Variation Rate,focus on the research of regularity on the pig industry chain.Explore the important product which impact price stability on the pig industry chain.From the data 2000-2009,we obtain results that the key factor which impact price stability on the pig industry chain is the price of piglet and pig.At the last,the paper give some suggests which how to stabilize the price of piglets and pigs.
