摘　　要：文章主要探讨玉米价格波动对生猪产品价格是否存在影响作用。文章聚焦研究国内玉米与生猪价格波动的动态关系,收集并处理2010年1月—2022年12月的月度数据,通过构建VAR模型,对两者关系进行分析。结果显示:玉米价格与生猪价格存在显著正相关,生猪价格是玉米价格的格兰杰原因,玉米价格不是生猪价格的格兰杰原因。研究表明,玉米价格和生猪价格之间的关系复杂而紧密,且两者关系也反映了农产品市场的相互依存性和复杂性。基于此,文章提出建立农产品信息平台、加强市场监管力度及扩大生猪养殖规模的建议对策。This paper mainly discusses the effect of corn price fluctuation on the price of pig products.This paper focuses on the dynamic relationship between domestic corn and pig price fluctuations,collects and processes the monthly data from January 2010 to December 2022,and analyzes the relationship between the two by constructing a VAR model.The results show that there was a significant positive correlation between corn price and pig price,and pig price is the Granger cause of corn price,while corn price is not the Granger cause of pig price.The study shows that the price of corn and the price of pigs are complex and close,and the relationship between the two also reflects the interdependence and complexity of the agricultural market.Based on this,the paper puts forward some suggestions on establishing an agricultural products information platform,strengthening market supervision and expanding the pig breeding scale.
