摘要： Due to the common influence of African plague and other factors, the price of pig in China has fluctuated frequently in recent years. This paper chooses the price fluctuation rate of every link of pig industry chain from January 2000 to February 2019 to analyze, and uses GARCH, GARCH-M, TARCH and EGARCH models to analyze the fluctuation and asymmetry of wave motion in each link. The results show that: (1)The price fluctuations of corn, feed, piglets, pig and pork have significant aggregation of fluctuations. (2)The corn, feed, pig and pork markets do not have the characteristics of high risk and high return, while the piglets market has the characteristics of high risk and high return. (3)In addition to the price of corn, the price fluctuations of feed, piglets, pigs and pork are asymmetric. Basis of the results of the study, some policy suggestions are put forward.
