摘　　要：以北京和河北两地为例,选取2014年1月6日-2020年12月28日金针菇、平菇、香菇的周度价格数据,利用相关系数、Granger因果检验、脉冲响应函数、方差分解等研究方法,对食用菌产销间价格传导机制进行研究。结果表明:北京、河北两地食用菌市场的价格具有较强的相关性,其中平菇和香菇市场是双向传导关系,金针菇市场则为单向传导关系;在价格传导速率方面,金针菇和香菇价格传导为2期滞后,平菇市场存在3期滞后;在北京、河北两地食用菌市场的价格形成中,平菇和香菇的价格传导属于“需求推动型”,金针菇的价格传导则属于“供给推动型”。为此,就需要建立健全食用菌产销间价格联合监测预警机制、推动食用菌种植农业合作社发展等措施,促进食用菌产业健康平稳发展。This research explored edible fungus price transmission mechanism between place of origin and sale market,by using correlation coefficient,granger causality test,impulse response function,variance decomposition method to analyse weekly price data of enoki mushroom,oyster mushroom and shiitake in Beijing and Hebei markets,from Jan.4,2014 to Dec.28,2020.The results showed that Beijing and Hebei had been linked closely to edible fungus market price,with the oyster mushroom and shiitake markets being two-way causal relationship and the enoki mushroom market being one-way causal relationship;The enoki mushroom and shiitake price transmission rate was 2-order lag,while the oyster mushroom was 3-order lag.Among the price formation in the edible mushroom market in Beijing and Hebei,oyster and shiitake price transmission type were“demand driven”,while the enoki price was“supply driven”.It is necessary to establish a robust joint price monitoring and early warning mechanism between edible fungus original and sale market,promote the development of agricultural cooperatives for edible fungus cultivation and other measures to promote the healthy and stable development of the edible fungus industry.
