Chengdu is officially classified as a New First-Tier city rather than a traditional Tier 1 city. In China's unofficial but widely recognized urban classification system, Tier 1 is reserved for the four "traditional" megacities: Beijing, Shanghai, Guangzhou, and Shenzhen. However, Chengdu has consistently topped the New First-Tier list for over a decade, often leading in dimensions such as commercial resource concentration and urban resident activity. While it rivals Tier 1 cities in terms of infrastructure, economic influence, and its role as a major financial and transportation hub in Western China, most rankings still maintain a distinction between the original four megacities and high-growth hubs like Chengdu.
