Code-switching and social change in Guangzhou and Hong Kong

This study seeks to investigate the shift of language practice in Hong Kong 
and Guangzhou, People's Republic of China. As Hong Kong's sovereignty 
has been returned to China, Putonghua (Mandarin Chinese) has made its 
way to Hong Kong, a Cantonese-speaking region with English as its official 
language in colonial times. In Guangzhou, also a Cantonese-speaking region, 
Putonghua, the national Standard language, is being used in more domains 
due to the economic development in the region. This study aims to show 
(1) how social changes such as economic reform and political change are 
reflected in the choice of language in Guangzhou and Hong Kong; (2) how 
the shift to language practice is indicated in code-switching between 
Putonghua and Cantonese in these two regions. The data for the study 
camefrom audio-recorded verbal interactions in Service encounters. I argue 
that code-switching between the two languages is an indicator of the 
changing political and economic situations in these two regions, which have 
brought about changes in ideology and business practice in current China. 
Implications for the use of Putonghua in these two regions will also be 
discussed
