摘 要：
为了解我国家禽类地理标志保护产品时空特征,以2002—2020年家禽类地理标志产品数据为依据,借助空间分析方法,从整体、部门和品种3个层面分析了我国家禽类地理标志的空间分布特征,应用莫兰指数从全局和局部两个维度对我国家禽类地理标志产品进行空间自相关分析。空间分布结果表明,家禽类地理标志登记整体呈增长趋势,空间上在南北方向上呈"南强北弱"分布,东西方向上呈"U型"分布,区域间分布差异明显;不同部门间家禽类地理标志登记增长趋势差异明显,省市分布呈"高数量省市少"的分布差异,空间上在南北方向呈"南强北弱"分布,东西方向差异明显;不同品种家禽类地理标志登记数量差异明显,受保护品种的资源占比情况与受保护品种总量占比不成正比,省市分布呈"高数量省市少,未申请省市多"分布,空间上呈"南强北弱,东强西弱"分布;空间自相关结果表明,在全局自相关上,部门综合、农业农村部和商标局的家禽类地理标志存在正的空间相关性,国家知识产权局家禽类地理标志不存在相关性;品种上,鸡和鹅类地理标志存在正的相关性,鸭和鸽类地理标志不存在相关性。局部自相关结果表明,已登记家禽类地理标志的省份中,大部分省份的地理标志保护情况会影响到邻近省份对家禽类地理标志的保护。在聚集差异上,家禽类地理标志在整体和部门间的聚集分布相似,均存在高-高聚集的省市集中于南部沿海地区,低-低聚集于北部地区,低-高聚集于中部和南部地区,高-低聚集于东部沿海地区现状。品种均存在高-高聚集于南部地区,低-低聚集于北部地区现状。总体上我国家禽类地理标志在中部地区和西部地区显著性差异不大。

摘 要：
In order to understand the temporal and spatial characteristics of the protection of geographical indications of poultry in China, based on the data of geographical indications of poultry products from 2002 to 2020, with the help of spatial analysis methods, the spatial distribution of geographical indications of poultry in China was analyzed from three levels: overall, department and variety. The Moran index was used to conduct spatial autocorrelation analysis of poultry geographical indication products from both global and local dimensions. The spatial distribution results showed that the overall registration of poultry geographical indications was increased, with a “strong south and weak north” distribution in the north-south direction, and a “U-shaped” distribution in the east-west direction, with obvious differences in regional distribution; poultry between different departments There were obvious significant differences in the growth trend of poultry geographical indication registration between different departments. The distribution of provinces and cities showed a “high number of provinces and cities but few”. The spatial distribution was “strong in the south and weak in the north” in the north-south direction, with obvious differences in the east-west direction; registration of geographical indications of different breeds of poultry. The quantity difference was obvious. The proportion of resources of protected varieties was not proportional to the total proportion of protected varieties. The distribution of provinces and cities was “high number of provinces and cities, and more provinces and cities without application”, and the spatial distribution was “strong in the south and weak in the north. The east was strong and the west was weak.” The spatial autocorrelation results showed that in terms of global autocorrelation, the poultry geographical indications of the departmental integration, the Ministry of Agriculture and Rural Affairs and the Trademark Office had positive spatial correlations, and the IP Office's poultry geographical indications did not exist. In terms of breeds, there was a positive correlation between the geographical indications of chicken and goose, and there was no correlation between the geographical indications of duck and pigeon. The results of partial autocorrelation showed that the protection of geographical indications in most provinces in the provinces that registered geographical indications of poultry would affect the protection of geographical indications of poultry in neighboring provinces. In terms of aggregation differences, the overall and inter-departmental aggregation distribution of poultry geographical indications was similar. The provinces and cities with high-high aggregation were concentrated in the southern coastal area, low-low aggregation in the northern region, and low-high aggregation in the central and southern regions. High-low clustered in the eastern coastal areas. There were high-high clusters in the southern region, and low-low clusters in the northern region. In general, there was little significant difference between the geographical indications of poultry in China in the central and western regions.
