中国省际食用菌产业集聚及空间差异化研究

Research on Interprovincial Agglomeration and Spatial Differentiation of China′s Edible Fungi Industry

基于2012—2021年我国25个省(市、自治区)食用菌相关统计数据,采用改良区位熵值法探究各地区食用菌产业集聚度及集聚变动趋势,并通过探索性空间数据分析法进一步对集聚度进行了空间差异化分析,以期为培育壮大食用菌产业并使之成为未来农业发展新增长点提供参考依据。结果表明:1)基于时序视角下,食用菌产业集聚变动趋势差异较大,东北地区的食用菌产业集聚水平始终最高,而河南、福建、黑龙江、吉林和江西是我国食用菌产业优势区域;基于空间视角下,食用菌产业集群呈现从东部地区开始向西南地区和西北地区扩展的转移态势。2)食用菌产业集聚整体上呈下降趋势,食用菌产业集聚空间自相关和集聚特征处于不断弱化的过程,集聚热点区域的总体格局保持稳定,总体呈现“东热”的空间格局,吉林、福建一直处于相对稳定的热点区域。我国省际食用菌产业集聚变动趋势差异较大,空间差异化显著,应培育壮大食用菌产业,加强结构性改革,积极创建优势特色食用菌产业集群,以促进食用菌产业高质量发展。

Based on the relevant statistical data of edible fungi from 25 provinces(municipalities and autonomous regions)in China from 2012 to 2021,the improved location entropy method was adopted to explore the agglomeration degree and agglomeration change trend of edible fungi industry in each region,and the spatial differentiation analysis of agglomeration degree was further carried out through exploratory spatial data analysis,in order to provide reference for cultivating and expanding edible fungi industry and making it a new growth point of agricultural development in the future.The results showed that,1)from the perspective of time series,the change trend of edible fungi industry agglomeration was quite different.Northeast region always had the highest level of edible fungi industry agglomeration,while Henan,Fujian,Heilongjiang,Jilin and Jiangxi were the dominant regions of edible fungi industry in China.From the perspective of space,the industrial cluster of edible fungi began to expand from the eastern region to the southwest and northwest regions.2)The agglomeration of edible fungi industry showed a downward trend on the whole,and the spatial autocorrelation and agglomeration characteristics of the edible fungi industry were in the process of weakening.The overall pattern of the agglomeration hotspot region remained stable,showed a spatial pattern of‘east heat’.Jilin and Fujian were in a relatively stable hotspot region.In conclusion,in order to promote the high quality development of the edible fungi industry,we should cultivate and expand the edible fungi industry,strengthen structural reform,and actively establish the advantageous and characteristic edible fungi industry clusters.
