INTEGRATION OF THE PEARL RIVER DELTA IN 1999—2019:AN ANALYSIS OF NEWS MEDIA ON GOVERNMENT PORTAL SITE

Since the beginning of the reform and opening, Pearl River Delta has experienced dramatical change, transforming from a backward agricultural county into a world factory and further into a global mega city- region. Regional integration has been always highlighted in a serial of regional planning documents regarding the Pearl River Delta. By searching news media on governmental portal sites of Guangdong and the relevant 9 cities, this study collects news media reports that contain keywords of Pearl River Delta and three metropolitan regions (i.e., Guangzhou-Foshan-Zhaoqing, Shenzhen-Dongguan-Huizhou, and Zhuhai-Zhongshan-Jiangmen) in their titles. These reports were identified and further grouped into four dimensions, namely, infrastructure, economy, society, and institution, according to text analysis of keywords in their title and content. Based on this, the study traces the regional integrations of the Pearl River Delta and three metropolitan regions. The differences among the four dimensions along the integration process are also discussed. Our findings show that the changes in news coverage of regional integration have been highly related to the regional planning formulation, as the Pearl River Delta and its integrations increased since 2004 while that of the three regions appeared after 2000.
