Core Viewpoint - The article discusses the contrasting strategies of different provinces in China regarding urban development, focusing on whether to strengthen the provincial capital or cultivate multiple economic growth centers. It highlights the need for precise identification of the leading cities' prominence and presents data on the economic primacy of 27 provincial capital cities, revealing significant regional disparities in development strategies [1]. Summary by Sections Economic Primacy of Provincial Capitals - The economic contribution of provincial capitals to their respective provinces is measured by the GDP share, with a threshold of 30% indicating a strong provincial capital. Nine cities exceed this threshold, including Changchun (53.47%) and Yinchuan (53.27%), indicating high dependency on these capitals for economic development [5]. - Eighteen cities have a GDP share below 30%, suggesting weaker economic influence or the presence of multiple supporting cities. Notably, Nanjing has the lowest share at 13.65% [5]. Classification of Provincial Capitals - The analysis categorizes the 27 provincial capitals into four types based on their GDP and population primacy ratios. Cities with both ratios above 2 are considered "one city dominates," while those with one ratio above 2 are classified as relatively strong [6][8]. - Strong provincial capitals identified include Chengdu, Wuhan, Changchun, Haikou, and Yinchuan, while weaker capitals include Nanjing, Jinan, and Hohhot [9]. Development Models - The article notes that the central and western regions tend to adopt a single-pole (strong provincial capital) development model, while the eastern coastal regions exhibit a multi-polar (weaker provincial capitals) development model [10]. - The report emphasizes the need for balanced development, with some regions showing potential for multiple trillion-yuan GDP cities, supporting a multi-point growth strategy [12]. Examples of Economic Structures - Guangdong has multiple trillion-yuan GDP cities, including Guangzhou and Shenzhen, while Jiangsu has five such cities, indicating a robust multi-polar development structure [12]. - In contrast, provinces like Sichuan and Shaanxi rely heavily on a single trillion-yuan GDP city (Chengdu and Xi'an, respectively), lacking sufficient supporting cities [16]. Future Development Directions - The article suggests that some provinces need to enhance their supporting cities to achieve balanced growth, while others should focus on strengthening their provincial capitals to maximize their economic impact [16].
