【摘要】：从蔬菜产业的纵向看,批发和零售是两个重要环节,蔬菜批发价格和零售价格的走势以及它们之间的关系是各界关注的焦点。本文以北京市场为例,以番茄和黄瓜两种果类蔬菜的按日批零价格为对象,运用有限分布滞后模型和误差修正模型进行实证分析,研究蔬菜批零价格间的传导关系,并在此基础上揭示蔬菜批发价格在蔬菜价格形成中的作用。研究发现:蔬菜批零价格走势基本一致,相关系数很高;批零价格间存在批发价格向零售价格单向传导的因果关系;批零价格的传导是顺畅的,但不同种蔬菜传导的时间效应有所不同;批发价格在蔬菜价格形成中占据主导作用,当蔬菜价格受到冲击时,若零售价格过高则其会向着批发价格下调,若批发价格过高则零售价格会随之走高。
[Abstract]:From the vertical view of vegetable industry, wholesale and retail are two important links, the trend of wholesale price and retail price and the relationship between them are the focus of attention. Taking the daily zero price of tomato and cucumber fruit vegetable as the object, using finite distribution lag model and error correction model, the conduction relationship between vegetable batch zero price was studied. The results show that the wholesale price of vegetables plays an important role in the formation of vegetable price. It is found that the trend of wholesale price of vegetables is basically the same and the correlation coefficient is very high, and there is a causal relationship between wholesale price and retail price. The transmission of batch zero price is smooth, but the time effect of different vegetable transmission is different. Wholesale price plays a leading role in the formation of vegetable price, and when vegetable price is impacted, the wholesale price plays a leading role in the formation of vegetable price. If the retail price is too high, it will go down to the wholesale price, if the wholesale price is too high, the retail price will rise.
