基于VAR模型的我国肉羊育肥饲料价格波动实证研究
Empirical study on price fluctuation of fattening feed for mutton sheep in China based on VAR model
摘要
Abstract
Based on the monthly data of 132 fattening feed prices for mutton sheep from January 2012 to December 2022,this paper selects soybean meal price,wheat bran price,mutton price,and natural disaster risk index as explanatory variables to analyze the influencing factors of fattening feed price fluctuation for mutton sheep in China.The results showed that the price of soybean meal had a significant impact on fattening feed of mutton sheep through an internal transmission mechanism.Natural disasters had obvious influence on the fluctuation of fattening feed price of mutton sheep through external impact mechanism.The fattening feed price of early mutton sheep had a significant impact on the fattening feed price of late mutton sheep.The study indicates that the conclusion of this paper can provide a reference for maintaining the long-term stability of fattening feed price of mutton sheep.关键词
