Spatial Distribution Patterns and Influencing Factors of Intangible Cultural Heritage in Guangdong Province of China

Intangible cultural heritage (ICH) constitutes a vital component of cultural diversity and a defining element of regional identity. Understanding its spatial patterns and determinants is fundamental to informing robust conservation strategies and ensuring its continuity across generations. This research employs kernel density analysis, average nearest neighbor analysis, and Poisson regression to examine the spatial distribution patterns and determinants of 3576 national, provincial, and municipal ICH items across 21 prefecture-level cities in Guangdong Province, China. The research results show the following: (1) All ICH categories in Guangdong province exhibit a significant spatial clustering, with Quyi (Chinese folk performing arts) demonstrating the most pronounced agglomeration, followed by traditional opera and traditional music. (2) Kernel density estimates display pronounced hotspots in the Guangzhou–Foshan core of the Pearl River Delta (PRD) and in Eastern Guangdong’s Chaozhou–Shantou corridor, while each heritage category displays its own geographically distinct footprint. (3) From the perspective of natural factors, ICH items are predominantly located in areas characterized by flat topography, proximity to rivers, and a mild subtropical climate, notably the coastal regions of the PRD, Eastern Guangdong, and Western Guangdong. These areas also possess superior resource endowments and transportation infrastructure. (4) Regarding socioeconomic factors, the analysis results point out distinct socioeconomic influences. Specifically, a larger registered population and higher per capita Gross Domestic Product (GDP) correspond to more ICH items. However, two factors demonstrate negative relationships: the total resident population and the level of dialect diversity. This study systematically elucidates the spatial distribution characteristics of ICH in Guangdong Province and their key influencing factors. The outcomes offer critical empirical evidence, thereby informing the design and implementation of optimized ICH conservation measures, promoting coordinated regional cultural development, and achieving the sustainable utilization of ICH resources.
