城市蔬菜供应链价格纵向传导机制研究——重庆的实证

On Vertical Transmission Mechanism of Urban Vegetable Supply Chain Price——an Empirical Analysis of Chongqing

本文依据价格传递理论,采用统计分析和协整计量模式,研究重庆蔬菜价格的纵向创导机理.结果表明重庆蔬菜零售价格盘旋上升,季节波动大,批零差价率高,3个环节的价格波动差异大.蔬菜价格的正向传导明显,且零售价格受到产地价格影响大于批发价格,但逆向反馈机制不明显.基于此提出加强市场总量及结构均衡研究,夯实稳定蔬菜价格的供应机制;支持建立新型流通模式,逐步形成充分竞争的价格形成机制;强化应急预警体系和信息发布体系建设,逐步形成抑制菜价波动的常态化管理机制;探索蔬菜价格管理和保险制度建设,形成蔬菜生产和消费利益补偿机制.

Based on the theory of price transmission and using the cointegration measurement model and statistical analysis,this paper researches the longitudinal guide mechanism of vegetable prices in Chongqing.The results showed that vegetable retail price in Chongqing spiraled upward,fluctuated seasonally and had a high wholesale and retail price differential.A large difference existed in price fluctuation of the three links.Vegetable prices exhibited an obvious forward conduction,and the origin price had greater influence on retail price than on wholesale price,but no obvious reverse feedback was noticed.Based on the above findings,this paper puts forward the following proposals:strengthen the market volume and keep the balance of the structure research so as to stabilize the supply of vegetable price mechanism;give support to the establishment of a new mode of circulation,so as to gradually form a fully competitive price formation mechanism;strengthen the construction of an emergency early warning system and an information release system,so as to gradually form a normalized management mechanism for inhibiting vegetable price fluctuation;and explore the path for constructing a vegetable price management and insurance system,so as to form a benefit compensation mechanism of vegetable production and consumption.
