The superposed sound change in Chinese dialects is a long-concerned issue.From the perspective of historical sociolinguistics,the present study takes Beixin village as a speech community where Guangshan dialect is spoken.Using the framework of language contact theory and sociolinguistic variation analysis,we analyze the mechanism of the substitution of colloquial readings by literary readings.From the author's experiences in the speech community,the demographic factors,the extra-community communication density,and the within-community communication density are generalized and calculated.By taking the proportion of literary readings as the dependent variable and all social factors as the independent variables,a multiple step-up regression model is formulated.The results show that the proportion of literary readings is significantly affected by age and the duration of schooling outside the township,while the within community communication density and the proportion of within community communication are not correlated with the proportion of literary readings.The acquisition of literary readings is more likely to be the result of individual acquisition from outside rather than a diffusion within the speech community.In this case,the essence of the superposed sound change is that monolinguals gradually become bilinguals.The study of external(social)factors helps to distinguish the internal change and contact-induced change.
