An Empirical Study on the Price Transmission of Edible Fungus between Production and Marketing: Based on Enoki Mushroom, Oyster Mushroom and Shiitake in Beijing and Hebei

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.
