博物馆是国家文化软实力承载实体之一，既聚集了地方文化，又作为文明的桥梁沟通古今中外。本文以广东省博物馆为研究对象，利用1990年-2020年的数据，使用ArcGIS等软件，以区县级以上的行政区划作为统计单元，借助数理统计和空间分析的方法，探讨广东省博物馆空间格局演变特征，并使用空间归因方法研究影响广东省博物馆时空格局演变的因素。结果表明：（1）广东省博物馆在数量和增长率上珠三角地区要明显优于非珠三角地区，致使广东省博物馆的增长走向与珠三角地区博物馆增长走向趋于一致；（2）广东省博物馆主要集聚于珠三角地区，在全省范围内呈现主要中心扩张、次中心增多的现象，以致分布重心移动轨迹呈“7”字形移动；（3）影响广东省博物馆空间分布的因素主要是经济因素，其次是社会因素，再者是文化因素。因此政府应在考虑经济、社会和文化的情况下合理地布局博物馆。

As one of the entities bearing the soft power of national culture, museums not only gather local culture, but also act as a bridge of civilization to communicate with the ancient and modern world. This paper takes the museum of Guangdong Province as the research object, uses the data from 1990 to 2020, uses ArcGIS and other software, takes the administrative divisions above the county level as the statistical unit, and uses the methods of mathematical statistics and spatial analysis to explore the evolution characteristics of the spatial pattern of museums in Guangdong Province. The spatial attribution method is used to study the factors affecting the spatio-temporal pattern evolution of museums in Guangdong Province. The results show that (1) the number and growth rate of museums in Guangdong Province is significantly better than that in non-Pearl River Delta region, so the growth trend of museums in Guangdong Province is consistent with that of museums in Pearl River Delta region; (2) The museums of Guangdong Province are mainly concentrated in the Pearl River Delta region, showing the expansion of main centers and the increase of sub-centers in the whole province, resulting in the movement of the center of gravity in a "7" shape; (3) The main factors affecting the spatial distribution of museums in Guangdong Province are economic factors, followed by social factors and cultural factors. Therefore, the government should rationally arrange museums in the context of economy, society and culture.
