China's Fifth-Largest Urban Agglomeration Confirmed! GDP Exceeds 12 Trillion Yuan, Wuhan Becomes the Leader, Optics Valley's "Four Little Dragons" Go Hot on A-Shares, Total Market Value Reaches 400 Billion Yuan, Yangtze Optical Fiber, Huazhong Technology and Others Board the AI Rocket

On March 18, the “Yangtze River Middle Reaches Urban Cluster” became a hot topic online. According to the “14th Five-Year Plan” outline released by the state, China’s fifth-largest urban cluster is designated as the Yangtze River Middle Reaches Urban Cluster. The document explicitly names five major urban clusters, supporting the development of world-class urban clusters in Beijing-Tianjin-Hebei, the Yangtze River Delta, and the Guangdong-Hong Kong-Macao Greater Bay Area, enhancing the development capacity of the Chengdu-Chongqing twin-city economic circle, and accelerating the growth of the Yangtze River Middle Reaches Urban Cluster.

Against the backdrop of the top three leading regions, over ten years ago, the Chengdu-Chongqing, Yangtze River Middle Reaches, Central Plains, and Guanzhong Plain urban clusters began competing for the fourth place. Around 2020, the Chengdu-Chongqing twin-city economic circle was elevated to a major strategic level, securing the “Fourth Pole” position among urban clusters, which then sparked discussions about the “Fifth Pole.”

According to the “14th Five-Year Plan” outline, among the 19 national-level urban clusters at that time, Chengdu-Chongqing and Yangtze River Middle Reaches were both in the first tier, while Shandong Peninsula and Central Plains were in the second tier. The current “14th Five-Year Plan” only mentions five major urban clusters, with the rest categorized under “others.” Previous top-level urban development documents emphasized promoting the Chengdu-Chongqing twin circles and Yangtze River Middle Reaches urban cluster as key growth poles for high-quality development, clearly defining the Fourth and Fifth Poles.

Regionally, Beijing-Tianjin-Hebei supports the north, the Yangtze River Delta leads the east, the Greater Bay Area drives the south, and Chengdu-Chongqing shoulders the western region. The central region previously lacked a core growth pole. As the most comprehensive, industrially advanced, and widely radiating urban cluster in the central region, the Yangtze River Middle Reaches Urban Cluster aligns with the strategic needs for the rise of central China.

Data for 2025 shows that the GDP of Hubei, Hunan, and Jiangxi provinces totals approximately 15.4 trillion yuan, about 11% of the national GDP. The Yangtze River Middle Reaches Urban Cluster’s GDP exceeds 12 trillion yuan, accounting for 9% of the national economy. The GDP of provincial capitals Wuhan, Changsha, and Nanchang are 2.21 trillion, 1.57 trillion, and 810 billion yuan respectively, totaling 4.59 trillion yuan, nearly 40% of the combined regional GDP.

According to Changjiang Daily, a week ago, the Wuhan municipal party and government delegation visited Changsha and Nanchang for inspections, marking the start of regional integration. State media openly stated that Wuhan, Changsha, and Nanchang joining forces form a “铁三角” (Iron Triangle) aiming to push China’s economy toward the “Fifth Pole.”

Currently, the Yangtze River Middle Reaches Urban Cluster has not yet formed a recognized leading city. Wuhan, Changsha, and Nanchang each have industrial advantages, but internal integration still needs to be promoted. From planning and positioning to truly becoming growth poles, there is still a long way to go.

Wuhan, known as the “Nine Provinces Thoroughfare,” has several leading advantages. In the capital market, Wuhan’s “Four Little Dragons” have recently been quite popular. Longfei Fiber, Huagong Technology, Guangxun Technology, and FiberHome Communications have all experienced remarkable doubling trends, with Longfei Fiber’s increase from its low point reaching tenfold. As of today’s close, the market values of these four companies are 148.5 billion, 115.4 billion, 67.4 billion, and 64.7 billion yuan respectively, totaling 400 billion yuan. All four companies are based in Wuhan Optics Valley and are hot stocks in the AI industry chain.
