In the competitive landscape of the Yangtze River Delta, Suzhou has long stood as an economic benchmark among non-provincial-capital prefecture-level cities. For years, Jiangsu has struggled to nurture a second city of comparable stature. Some scholars argue that the province once had a golden opportunity to cultivate such a powerhouse—by accelerating the deep integration of the Suzhou-Wuxi-Changzhou (Su-Xi-Chang) metropolitan area, particularly by promoting the joint development of Wuxi and Changzhou. Geographically close and culturally similar, these two cities share a natural foundation for integration. Both have built substantial economic foundations over decades, sparking hopes of generating new growth momentum through collaboration.
The concept of the Su-Xi-Chang metropolitan area has been around for over two decades, with initial planning dating back to the 1990s. It was later incorporated into the core of the Yangtze River Delta integrated development strategy, raising high expectations. Many hoped this region would produce a second growth pole, easing Suzhou’s development pressures while upgrading the entire southern Jiangsu (Sunan) area.
For years, the most vocal calls from the public and academia have centered on the deep integration of Wuxi and Changzhou, including rumors of administrative merger. The urban areas of the two cities are remarkably close—a drive of less than an hour—and their languages, customs, and habits are nearly identical. Industries also show potential for complementarity. Many believe that if these two cities could join forces, they could challenge Suzhou’s leading position. This topic has been debated for years precisely because expectations are so high.
However, while many focus on the impressive combined GDP of the Su-Xi-Chang trio, they overlook significant internal industrial divergence. Public data for 2022 reveals that Changzhou’s high-tech manufacturing growth rate reached 45%, far exceeding Wuxi’s 12.1% and Suzhou’s 7.5%. This stark difference highlights an uneven industrial structure within the region. What was once seen as a perfect complement—Wuxi’s Internet of Things (IoT) and Changzhou’s smart manufacturing—has turned into direct competition in the new energy sector. Wuxi focuses on solar photovoltaic component production, while Changzhou pushes lithium battery capacity, aggressively competing for markets, supporting facilities, and investment. This is less about collaboration and more about homogeneous competition in a crowded space.
Another often-overlooked issue is talent mobility within the metropolitan area. There is a clear gradient in public services among Suzhou, Wuxi, and Changzhou. Suzhou, being closer to Shanghai, offers superior medical and educational resources, attracting many high-end talents trained in Wuxi and Changzhou after a few years of work. This exacerbates the brain drain, leaving both cities struggling to retain talent. Moreover, industrial policies across the region are all targeting the same hot spots—new energy, high-end manufacturing—leading to disorderly competition and resource misallocation. If this trend continues, it could result in regional overcapacity and wasted resources.
Many observers note that the challenges of Su-Xi-Chang integration mirror common problems in most Chinese metropolitan areas: the rhetoric of collaboration often masks a reality of each city competing for its own interests. Each city has its own development targets, and no one wants to give up advantageous projects. Even when paying lip service to coordination, actual actions tend to prioritize self-interest.
Looking ahead, the Su-Xi-Chang metropolitan area faces substantial obstacles. Administrative barriers remain significant. For instance, the Guangzhou-Foshan integration has been ongoing for decades, yet cross-city public services like medical insurance settlement and school enrollment are still not fully interoperable. This shows how administrative constraints can hinder regional integration, even when there is a willingness to merge. The current industrial homogeneity already poses a threat; without timely adjustment of division of labor, the region could follow the wrong path taken by the Tokyo metropolitan area during its integration. In Tokyo’s case, traditional industries moved outward while emerging industries failed to upgrade internally, leading to industrial hollowing out in some areas. Today, over 40% of Japan’s automobile production is overseas, and its overall manufacturing competitiveness has been surpassed by China. Many people merely see the GDP boost from merging cities, ignoring the hidden risk of industrial hollowing out.
Even if Wuxi and Changzhou were to merge into a megacity with a total GDP matching Suzhou’s, it would not guarantee a replication of Suzhou’s success. The Su-Xi-Chang region has achieved remarkable progress, but structural problems lurk beneath the surface. The direction of coordinated development is sound, but practical implementation faces real challenges like industrial homogeneity, talent drain, and administrative barriers—issues that cannot be resolved overnight.
An alternative perspective worth exploring is why there is such an obsession with enlarging the administrative scale of a single city. Could a different approach be considered—such as forming a virtual city alliance based on digital technology, without the need for administrative merger? This would likely carry much lower social costs than forced consolidation. Some netizens joke: “If the merger really creates a megacity, wouldn’t going to the dinosaur park from Wuxi to Changzhou be like crossing a province? It might even surpass Suzhou.” This humorous comment reflects the public’s casual observation of the issue.
Objectively, people should not get overly excited about administrative merger, nor should they completely dismiss the benefits of coordinated development. What truly
