- 摘要:
- 我国是世界上最大的食用菌生产国,在近年来的发展中,我国的食用菌生产空间布局也进行着改变。基于2003—2015年我国各地区(省、市、区)的面板数据,运用区域重心分析法描绘并分析了我国食用菌生产空间的变迁轨迹,而后利用空间计量经济模型对影响食用菌生产转移的因素进行了模型估计。结果表明:食用菌生产的空间布局从我国中、东部地区向东北地区转移的迹象较为明显,而食用菌的生产整体呈现空间正向效应,即某一地区的食用菌生产会受到周边地区的正向影响。在所引入的变量中,木竹材产量占比、第一产业从业人员数量占比、农村居民人均纯收入对食用菌的生产集中度呈正相关,城镇居民人均可支配收入对其呈负相关。
- 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.
