Study on the Spatial Distribution Pattern of Catering Industry in the Urban Center of Kunming from 2012 to 2022

Abstract

Taking the urban center of Kunming as the study area, this paper extracts the POI data of the catering industry in 2012, 2016, 2020 and 2022 of Kunming by adopting web crawler technology, and then the average nearest neighbor index, geographic concentration index, kernel density analysis and spatial autocorrelation index are used by this study to conduct a comparative study on the spatial distribution pattern of the catering industry in the urban center of Kunming so as to explore its spatial clustering and evolutionary characteristics. The study results show that: (1) The development trend of the spatial pattern of the catering industry in the urban center area of Kunming is consistent with the urban development planning of Kunming, with the center clustering and expanding outward. (2) Although relying on commercial centers, tourist hotspots and university campuses, catering points form a multi-center distribution and "large aggregation, small dispersion" spatial pattern, the spatial distribution is unbalanced. (3) The spatial distribution pattern of catering industry is consistent with the overall spatial distribution pattern of catering industry, showing a multicenter gathering trend.
