Abstract:: China is the most productive country of edible fungus in the world.However,the spatial distribution of edible fungus production in China was changing with the passage of time.This study used the panel data of 30 provinces in China from 2003 to 2015 and applied regional gravity center method to describe the spatial evolvement track about edible fungus production gravity center.The results turned out that the spatial production had changed from south to north obviously.In the influencing factors analysis part,Moran′s I about edible fungus production concentration was calculated with positive value.Estimation results of SEM panel fixed-effect model showed that there was a positive spatial effect.The production concentration ratio of edible fungus was affected positively by the wood and bamboo outputs,amount of employment in agricultural industry and rural per capita net income,affected negatively by the urban per capita disposable income.The results also indicated that the natural resource and labor recourse still played an important role in the edible fungus production.The high disposable income urban area would exclude edible fungus production while the high income rural areas would attract the edible fungus production.
