城市化是一个复杂的体系,城市化移民涉及诸多变量。从社会语言学的角度进行分析,可以发现不同社会变量的社会语言学影响是不同的。那些离家较远、弱连接越丰富、期望留在城市、职业较开放、收入较高、异质型居住的移民,最易出现语言变异或者接受新的语言形式。虽然城市化无疑会有助于普通话的传播和使用,但是一些变量依然会成为阻碍的因素。正在进行的中国城市化进程将为社会语言学研究提供一片沃土。 Urbanization is a complex system, and urbanization involves many variables. From the perspective of sociolinguistics, we can find that the social linguistic influences of different social variables are different. Those immigrants who are farther away from home and have weaker connections, who are expected to stay in the cities, are more open-minded, earn higher incomes and are heterogeneous, are most likely to experience linguistic changes or accept new forms of language. Although urbanization will undoubtedly contribute to the spread and use of Putonghua, some variables will still be a deterrent. The ongoing process of urbanization in China will provide fertile ground for sociolinguistic research.
