Abstract: China now is in the transition period of food structure,accompanied by strong growth in demand for livestock products. The prices of livestock and forage products are generally rising and more easily influenced by other factors. Hence,the change rules,correlation and Granger Causality Test of the price of domestic and international major livestock and forage products from September 2008 to August 2013 are analyzed in this article. 1) The prices of domestic and international livestock and forage products indicate an upward trends with fluctuations,while the prices of domestic and international “herbivorous” livestock products are higher than those of “grain consuming” and the prices of domestic major livestock and forage products are higher than the international ones; 2) Except the prices of domestic pork and beef,prices of domestic livestock products and forage fluctuate more than the international ones; 3) The domestic prices of pork and beef as well as the international prices of “herbivorous” livestock products show higher fluctuations. In addition,results of Granger Causality Test indicate that the changes of domestic soybean grain prices are caused by international soybean grain prices; the changes of domestic soybean grain prices are caused by domestic beef and mutton prices,the changes of domestic soybean meal prices are caused by domestic beef prices and the changes of domestic chicken prices are caused by domestic maize grain prices; the changes of international soybean grain and maize grain prices are caused by international beef prices. Above all,the prices of livestock products are signally affected by agricultural policies,festival and dietary habit. In conclusion,the study suggests that developing grassland agriculture is a way to stabilize the prices of livestock products and ensure the safety of livestock products; the country should increase direct subsidies to farm households and provide policy supports and services for their production.
