Geographical indication(GI)products are distinctive regional resources protected by intel-lectual property rights.Understanding their spatial distribution patterns is of great significance for pro-moting regional economic development and rural revitalization,especially in mountainous areas.Based on 683 GI products across 13 categories in Fujian Province,this study analyzed their category structure via mathematical statistics,described their temporal and spatial evolution patterns using kernel density estimation,and explored the factors driving their spatial differentiation at the county scale employing Geodetectors and geographically weighted regression(GWR)models.The results show that:GI products in Fujian Province exhibit rich diversity but an unbalanced structural composition,dominated by fruits and nuts(accounting for 20.79%of the total),followed by aquatic products and products,vegetables and fungi,tea and livestock and poultry products;these top five categories collectively account for 71.89%of the total.Since 2000,the number of GI products in Fujian Province has increased steadily,expanding spatially from Southern Fujian to the entire province,ultimately establishing a"one-pole,multi-core"spatial distribution pattern characterized by Zhangzhou as the core growth pole and high-density clusters coexisting in Longyan,Quanzhou and Ningde.The influencing factors display marked spatial heterogeneity,among which slope,population density,and transport accessibility emerge as the primary driving factors.These findings provide theoretical references for developing county-level specialty agricultural industries in Fujian Province and offer practical guidance for the cross-regional linked development of advantageous product categories in mountainous areas.
