A Network Evolution Model for Chinese Traditional Acquaintance Networks

The evolution model of Chinese traditional acquaintance relationship networks described in this article emphasizes individual heterogeneity and social culture. The model incorporates three distinct mechanisms that affect acquaintance network evolution and formation: heredity linking, variation linking, and similarity-based disconnection. The authors found that the degree distribution of Chinese traditional acquaintance networks is manifested in a piecewise approximation that combines a power-law form with an exponential cutoff and exponential distribution. Numerical results indicate that individuals maintaining a medium amount of connections far outweigh others, reflecting the characteristics of Guanxi-centered society. The formation of acquaintance relationship networks is greatly affected by the special Chinese kinship culture. The authors' findings are supported by sociological statistical conclusions and offer a rational explanation for the nature of Chinese kinship networks. Their work provides an adequate framework for further research on dynamic human complex behaviors such as epidemic spreading and rumor propagation.
