摘要/Abstract

摘要：

古镇类旅游地的商业同质化是该类旅游目的地同质化的主要表现，这种现象在一定程度上促进了旅游地的经济发展，但也影响到了游客的旅游体验，导致了目的地商业经营的无序局面。论文以大理古城为例，通过编程获取大理古城内部的街景图像数据，并利用计算机视觉、机器学习等技术识别出街景图像中的店铺标牌文字信息。在此基础上构建指标模型，对案例地商业同质化进行测度，探讨了古镇旅游地商业同质化的空间特征及其形成机制。结论如下：① 大理古城总体商业同质化的空间分布呈现核心—外围特征。商品经营型店铺在旅游核心区的商业同质化程度高，表现出街道分布的特点；而服务经营型店铺在旅游外围区的商业同质化程度高，表现出街区分布的特点。② 旅游资源分布、规划调控、区位条件和资本介入是导致商业同质化的主要因素，竞争和聚集是形成商业同质化的2种主导机制。③ 利用计算机视觉与机器学习等技术提取街景图像中的店铺标牌文字信息，将同类型店铺的重复数量和集聚水平作为指标构建模型并结合GIS空间分析方法，能够实现对古镇旅游地商业同质化的空间测度。该研究的数据处理方法与模型构建方法可丰富利用街景图像进行的社会景观研究，相关结论可为古镇旅游地的管理和高质量发展提供参考。

Abstract:

The commercial homogenization of ancient town tourism destination is the main manifestation of the homogenization of this type of tourism destination. Although to some extent this phenomenon promotes the economic development of the tourism destination, it also affects the tourism experience of tourists and leads to the disorder of the commercial operation of the destination. Taking Dali ancient city as an example, this study obtained the street view image data inside the ancient city through programming, and used computer vision, machine learning, and other technologies to identify the shop sign text information in the street view images. On this basis, this study constructed an index model to measure the commercial homogeneity of the case, and examined the spatial characteristics and formation mechanism of the commercial homogenization of the ancient town tourism destination. The conclusions are as follows: 1) Spatially, the overall commercial homogeneity of Dali ancient city presents the characteristics of core-periphery distribution. The commercial homogenization degree of stores is high in the core tourism area, showing the characteristics of street-level distribution, while the commercial homogenization degree of service firms is high in the peripheral tourism area, showing the characteristics of city block-level distribution. 2) The distribution of tourism resources, planning and regulation, location conditions, and capital intervention are the main factors leading to commercial homogenization. Competition and spatial aggregation are the two leading mechanisms to form commercial homogenization. 3) Using computer vision and machine learning technologies to extract the shop sign text information in the street view images and taking the repetition number and agglomeration level of the same type of shops as indicators to build a model, combined with GIS spatial analysis method, we can realize the spatial measurement of the commercial homogeneity of the ancient town tourism destination.
