农业品牌建设对耕地空间聚集度的影响
Impact of agricultural brand building on spatial agglomeration degree of cultivated land
摘要
Abstract
[Objective]The impact of geographical indication(GI)certification of agricultural products on the spatial agglomeration degree of county-level cultivated land and its pathways were evaluated from spatial perspective in order to provide decision-making reference for promoting regional specialty agriculture and effectively enhancing the agglomeration degree of cultivated land.[Methods]Based on county-level annual cultivated land raster data from the CACD(2024),ArcGIS and Fragstats were used to construct indicators of cultivated land spatial agglomeration at the county level.A multi-period difference-in-differences model and a two-way fixed effects model were employed to identify causal effects and to systematically examine the internal logic of the impact of agricultural brand building on the spatial agglomeration of cultivated land.[Results]① GI certification significantly enhanced the spatial agglomeration degree of county-level cultivated land,with the spatial agglomeration degree of county-level cultivated land increasing by an average of about 0.113 after certification.② GI certification strengthened the spatial agglomeration of cultivated land by promoting the development of agricultural industrialization and improving the dynamic balance level of total cultivated land.③ The effects of GI certification were more significant in counties with lower terrain slopes and higher levels of agricultural mechanization.④ GI certification also generated positive spatial spillover effects on adjacent non-certified counties.[Conclusion]Expanding the newly added scale of agricultural brands,improving the quality level of existing brands,and optimizing the spatial layout of brands can further unlock the effectiveness of brand building policies,thereby becoming an effective pathway for optimizing the spatial patterns of cultivated land and enhancing national food security capacity.关键词
