摘要
利用VAR模型和Granger因果关系检验,刻画我国猪肉价格、牛肉价格、羊肉价格之间的互动关系,结果表明:从长期来看牛肉、羊肉和猪肉价格波动的最主要因素在于其自身的波动;羊肉价格对牛肉价格的影响程度大于猪肉价格的影响程度;牛肉对羊肉价格的影响大于猪肉价格对羊肉价格的影响;猪肉价格与牛肉价格互为Granger原因,牛肉价格与羊肉价格互为Granger原因;牛肉价格与猪肉价格呈现反向关系,据此可通过调控相关肉类价格稳定肉类市场价格.
The article uses the VAR model and the Granger causality test to explore the interaction between pork prices and beef and mutton prices.The results show that the most important factor in the future price fluctuations of beef,lamb and pork is its own fluctuations;The effect of price on beef price is greater than that of pork price.The effect of beef on lamb price is greater than the effect of pork price on lamb price.Pork price and beef price are Granger reasons.Beef price and lamb price are Granger reasons.The price has an inverse relationship with the price of pork.According to this conclusion,the overall market price of meat can be stabilized by regulating the price of related meat.
