Core Viewpoint - The article discusses the recent administrative changes in Foshan, Guangdong, where nine administrative villages from Zhaoqing's Gaoyao District were transferred to Foshan's Gaoming District, primarily driven by the construction of the new airport in the Pearl River Delta region, referred to as the "Guangzhou Second Airport" [4][5][6]. Group 1: Airport Development and Urban Expansion - The new airport, designed to handle 30 million passengers annually, is located at the boundary between Foshan and Zhaoqing, approximately 80 kilometers from Guangzhou [10][18]. - Foshan's administrative adjustment is seen as a necessary step to facilitate the integrated planning and construction of the airport, breaking down administrative barriers [19][20]. - Foshan joins cities like Xi'an and Chengdu that have expanded due to airport developments, marking a trend of urban growth linked to transportation infrastructure [8][21]. Group 2: Comparison with Other Cities - Over the past decade, five major provincial capitals have undergone significant expansions, with Chengdu and Xi'an being directly related to airport developments [22]. - Chengdu's expansion in 2016 involved the incorporation of Jianyang, which added over 2,200 square kilometers and 1.4 million residents, enhancing its economic capacity [24]. - Xi'an's integration of Xianyang has been a long-discussed topic, with recent plans indicating a shift towards collaboration rather than outright merger [32]. Group 3: Future of Urban Expansion - The article suggests that while Foshan's adjustment is a minor administrative change, it does not signify a broader trend of urban expansion, especially since the last significant expansion occurred in 2020 with Changchun [36][40]. - Current urban development is shifting from rapid expansion to improving existing urban areas, indicating that large-scale city mergers or expansions are unlikely in the near future [39][41]. - The focus is now on addressing the needs of shrinking cities and potential administrative adjustments rather than pursuing new expansions [42].
