Research is being conducted on the evolution and distribution of intangible cultural heritage in coastal areas of China, with a focus on understanding the driving mechanisms and influencing factors. The studies appear to be using various methods, including machine learning, to analyze the spatiotemporal patterns and characteristics of intangible cultural heritage in regions such as the Guangdong-Hong Kong-Macao area. The research also explores the relationship between intangible cultural heritage and tourism in these areas.
