Abstract: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 Offices 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.
