摘要
鸭梨是河北省主要水果,其价格波动直接影响梨农的经济效益。基于2012-2019年河北省鸭梨月度价格数据,采用X-12季节调整模型和H-P滤波法,对河北省鸭梨价格波动规律和影响因素进行分析。结果表明,季节成分和随机因素对鸭梨价格波动影响显著;鸭梨价格波动呈长期上升趋势,且具有一定的周期性;产量受气候条件等因素影响呈不稳定状态,对鸭梨价格波动影响较大。研究提出河北省鸭梨应加强规模化生产、新品种研发、冷库仓储设施和风险防控机制建设,以进一步稳定生产,促进鸭梨市场价格的稳定。
As the main fruit in Hebei province,the price fluctuation of Yali pear directly affected the economic benefits of fruit growers.Based on the monthly price data of Yali in Hebei province from 2012 to 2019,the fluctuation law and influencing factors of Yali pear price in Hebei province were analyzed by using X-12 seasonal adjustment model and H-P filtering method.The results showed that seasonal components and random factors had significant effects on the fluctuation of Yali pear price.The fluctuation of Yali pear price showed a long-term upward trend and had a certain periodicity.The yield was unstable under the influence of climate conditions and other factors,which had a greater impact on the fluctuation of Yali pear price.To further stabilize the production and promote the stability of Yali pear market price,Hebei province should strengthen the large-scale production,research and development new varieties,cold storage facilities and risk prevention and control mechanism construction.
