农产品批零价格的联动性是反映批零市场一体化程度和流通效率的重要指标。本文利用ECM模型实证分析发现,农产品批零价格存在协整关系,总体保持了一致的变动态势,零售价格均值比批发价格高0.8个百分点,批发价格标准差比零售价格高1个百分点。农产品批零价格均衡误差对波幅均具有显著的影响作用,批发价格具有相对较强的自我稳定性,零售价格则具有相对较强的自主波动性。最后,本文认为提高农产品批零价格联动性,应提高批零环节的信息化、组织化、一体化水平。
The linkage of wholesale and retail prices of agricultural products is an important indicator of the degree of integration of wholesale and retail markets and the efficiency of circulation. In this paper, empirical analysis using ECM model found that there is a cointegration relationship between wholesale and retail price of agricultural products, and generally maintained a consistent trend of change. The average retail price was 0.8 percentage point higher than the wholesale price. The wholesale price standard deviation was 1 percentage point higher than the retail price. The balance error of wholesale and retail prices of agricultural products has a significant effect on volatility. Wholesale prices have relatively strong self-stability, and retail prices have relatively strong independent volatility. Finally, this paper believes that to improve the linkage of wholesale and retail prices of agricultural products, we should increase the level of informationization, organization and integration in the process of batch zeroing.
