Abstract: In this paper, we analyze the cultural pattern of Chinese online music society using the dataset collected from NetEase Cloud Music. Our analysis focuses on the region diversity of user’s favorite music, and average preference diversities defined on the region diversity. We calculate the region diversity and the average preference diversity of users at each region, and analyze the correlation between these diversities and the development level of economy, and find that users in the developed regions have higher probability in following niche music. And also, we detect two major musical cultural circles from the differences on the distribution of user’s region diversity of each area, and analyze the correlation between region diversity and the diversity on the source of residents to investigate the cultural impact of migration. These findings provides series of global feature on Chinese cultural structure from the perspective of music.
