摘  要:
分别从供给和需求两个层面来阐述引起中国生猪价格波动的主要影响因素,通过建立多元线性模型和1阶AR(1)模型对"季节调整"后的数据进行回归分析,以此测度各主要因素对生猪价格的影响程度。结果表明,生猪价格波动的原因主要来自于供给方面,从回归结果来看,生猪价格与仔猪价格、玉米价格、鸡肉价格呈正相关,与生产者预期、疫情呈负相关,其中玉米价格的波动对生猪价格影响最大,其次是仔猪价格。提出了要稳定玉米价格及高效安全的饲料供应、保障能繁母猪达到合理规模、健全生猪生产和市场的预警机制、强化生猪疫病防治体系的建设等政策建议。

摘  要:
The factors affecting price fluctuation of live pig in china were discussed from the aspects of supply and needs.Regression analysis of data treated by seasonal adjustment was carried out using multivariate linear model and 1 order AR(1) model to measure the influencing degree of the main factors.The results showed that the price of live pig was positively correlated with price of piglets,corn price and chicken price,negatively correlated with expectation of producer and epidemic situation,among which the effect of fluctuation of corn price was corn price,followed by piglet price.Suggestions including stabilizing the corn price and efficiency and safe feed supply,keeping the scale of reproducible cow at reasonable level,perfecting the warning mechanism of live pig production and market;and strengthening the construction of live pig epidemic disease control system were proposed.
