Abstract The top 300 Chinese surnames are analyzed with the spatial autocorrelation method to confirm the characteristics of Chinese surnames’ concentration. A new index, diffusion distance, is proposed to quantify the spatial ranges of the concentration characteristics and the results are qualitatively explained from the perspective of the population mobility in Chinese history. Our specific results for the top 300 Chinese surnames are the following: The significant spatial autocorrelation of the relative frequencies generally exists within a short spatial range. About half of the surnames have a diffusion distance between 400 kilometers and 800 kilometers. There is a positive correlation between the diffusion distances of the surnames and their population sizes. That is, the diffusion ranges of larger-scale surnames are wider, which may be related to their longer history.
