本文以蔬菜价格波动特征分析入手,对蔬菜价格内部传导及其内生因素的涵义进行了界定,并利用2003—2010年省际面板数据的PVAR模型,对蔬菜价格波动与其内生因素的相互作用进行了实证分析。结果显示,中国蔬菜产业市场还不完善,效率还不高,蔬菜产业内部传导存在明显的滞后性,部分冲击反应与传统理论分析并不相符,具体表现在蔬菜价格形成机制不畅,价格调节机制单向有限地发挥着一定的作用。
This paper starts with the analysis of vegetable price volatility, defines the internal conduction of vegetable price and its endogenous factors, and uses the PVAR model of provincial panel data from 2003 to 2010 to analyze the interaction between vegetable price volatility and its endogenous factors Conducted an empirical analysis. The results show that the vegetable industry in China is not yet perfect and its efficiency is not high enough. There is a significant lag in the internal conduction of the vegetable industry. Some of the impact reactions do not match the traditional theoretical analysis, which is manifested in the poor mechanism of vegetable price formation and the price adjustment mechanism One-way limited play a certain role.
