广西地理标志农产品空间分布与品牌溢出效应研究

Study on the Spatial Distribution and Brand-spillover Effect of Geographical Indication Agricultural Products in Guangxi

地理标志农产品在地区经济发展和农户增收中表现出明显的溢出效应,成为脱贫攻坚与乡村振兴中产业选择和农业现代化的重要资源。通过地理集中指数和面板数据分析模型分析了广西地理标志农产品空间分布特征及其2010—2018年品牌溢出效应与地区差异。结果显示:广西地理标志农产品总体上呈现局部集中、总体均匀分布,自然资源丰富且组合较多的地区集中指数较高;地理标志农产品对广西农村经济发展有正向促进作用,但还较弱;对农民人均可支配收入的溢出效应比农业生产总值显著,同时品牌溢出效应区域差异也较为明显。广西大部分地理标志农产品呈现初步产业化,但品牌溢出效应尚待挖潜。

The agricultural product of geographical indication(GIs)has great economic potential and spillover effect on rural development.Based on the geographical concentration index and panel data analysis model,the purpose of this paper was to analyze the spatial distribution characteristics,brand-spillover effects of from 2010 to 2018,and regional differences of GIs in Guangxi province.To begin with,the geographical concentration index indicates that GIs are evenly distributed in Guangxi.ArcGIS visualization also shows that the quantity of GIs is distributed uniformly on the whole,while there are some areas where it is relatively concentrated.The county-level statistics shows that the northeast of Guangxi is more concentrated,followed by the northwest.Furthermore,Panel data model analysis demonstrates that the GIs of Guangxi have a positive role in promoting rural economic development,but they are still weak.The spillover effect on farmers’per capita disposable income is more prominent than on gross agricultural output value.Meanwhile,there are great differences in brand spillover effects among different regions.In conclusion,most of the GIs in Guangxi have gradually formed the industrialization development,but the brand spillover effects have not been fully exploited.
