Recently, the Shanghai Railway Bureau announced that this year it will begin construction on the following projects: the Shanghai-Suzhou-Huzhou Railway, the Yancheng-Tongling Railway, Phase II of the Shanghai-Tongling Railway, the Anqing-Jiujiang Railway, the Changjing-Huangshan Railway, the Huangchi Railway, the Yongjin Railway, the Hangzhou-Shaoxing-Taizhou Railway, the addition of third and fourth tracks between Zhuangqiao and Ningbo, the electrification and outer bypass of Bengbu along the Shui-Beng line, the Dafeng Port branch line, and the Huzhou West Freight Yard. 12 One project, with an investment scale of approximately 2262 hundred million yuan, including the Shanghai-Suzhou-Huzhou Railway and Phase II of the Shanghai-Tong Railway, which are directly related to Shanghai.

In the Yangtze River Delta—especially in northern Jiangsu and Anhui provinces—people are most eager to discuss: “Now that the high-speed rail is here, what kind of changes will it bring?” When people from the Yangtze River Delta travel for business or tourism, their first instinct is to head online and buy high-speed rail tickets. For instance, places like Quzhou and Lishui in Zhejiang, which used to be remote areas that took at least a day’s journey by road for Shanghai residents, now take only two or three hours. Similarly, cities like Nantong and Taizhou in Jiangsu, once requiring long-distance sleeper buses—and sometimes even ferry crossings over the river—are soon to become accessible via the newly opened Shanghai-Nantong Railway. With its opening, traveling to the north bank of the Yangtze River from Shanghai will feel as effortless as “drinking a cup of coffee.”

What high-speed rail has transformed is perhaps not just the convenience of daily life; from a longer-term perspective, the high-speed rail network can further enhance the regional innovation capacity of the Yangtze River Delta urban agglomeration. At a higher stage of integration, the functions and roles of cities will become even clearer.

The high-speed rail network accelerates the flow of economic factors.

The high-speed rail era has accelerated the flow of people and goods, accompanied by the simultaneous surge in capital flows, technology transfers, and information exchanges—and the resulting radiating effects. As production factors start moving, the economy naturally heats up.

In recent years, the integrated development of the Yangtze River Delta has been closely linked to the construction of its high-speed rail network. Older generations still remember the early days of road travel, when one had to carefully plan their time and find lodging for the night. With the rapid expansion of expressways and the construction of grand bridges spanning rivers and seas, key cities in the Yangtze River Delta metropolitan area have become seamlessly connected. Today, the high-speed rail era has further accelerated the flow of people and goods, accompanied by the simultaneous surge in capital flows, technology transfers, and information exchanges—and the resulting ripple effects. As production factors start moving more freely, the economy has begun to thrive.

the last century 60 With the launch of Japan's Tokaido Shinkansen, several metropolitan areas have been brought under its coverage. X The “hourly economic circle” has boosted industrial development and division of labor along its route. In his view, building a high-speed rail network in the densely populated Yangtze River Delta region is the right move at this stage. This year, the Yangtze River Delta... 12 The commencement of a railway project will further densify the high-speed rail network, which is an effective way to maximize the benefits of high-speed rail. Chen Jianjun believes that in the future, intercity railways and urban rail systems could also be integrated into a single, comprehensive railway network, enabling economic factors to cluster even more closely along railway lines.

Not only transportation hubs like Shanghai, Nanjing, Hangzhou, and Hefei benefit from the high-speed rail network—some county towns and small towns are also eagerly anticipating its advantages. First, the high-speed rail has “shortened” the distances between these localities and provincial capitals or even Shanghai itself. Second, high-speed rail stations are generally located in suburban areas that lie somewhat away from the county centers, which is highly conducive to the development of a new type of urbanization. Reporters have noted that many counties and districts have already begun developing distinctive “high-speed rail new cities.”

City positioning is becoming clearer thanks to high-speed rail.

In the future, Shanghai’s rail transportation network will extend beyond the Shanghai-Nanjing and Shanghai-Hangzhou corridors. To the north, it will connect to Nantong; to the south, it will link to Ningbo; and in between, it will also reach Huzhou. The high-speed rail network will make it even more convenient for markets to connect with production areas.

Although many people have high expectations, the economic boost that opening high-speed rail lines brings to a region is ultimately indirect. What can be observed so far is that cities in the Yangtze River Delta are becoming increasingly clear in their positioning and functional roles.

Take Hefei, for example: thanks to the development of its high-speed rail network, it has become a new railway hub and is already demonstrating strong talent attraction in Anhui Province. Hefei’s advantages lie in its rapid growth in high-tech industries and low business costs. In the future, Hefei—just two or three hours away by high-speed rail from Shanghai—will be able to achieve mutual benefits and win-win outcomes with Shanghai. For instance, in terms of commercializing scientific research findings, Shanghai can serve as the global source of cutting-edge technologies, while related research results can be transferred to Hefei for further development and application. Shanghai can evolve into a research and development center and a regional radiation hub, whereas Hefei plans to be developed into an advanced manufacturing center and a base for high-tech industries. Moreover, cities like Ma'anshan and Wuhu in Anhui have already experienced a “same-city effect” with Nanjing due to the high-speed rail connection; as a result, some manufacturing companies are now leveraging Nanjing’s scientific and educational resources to undergo transformation and upgrading.

Shanghai is also benefiting from the high-speed rail network in the Yangtze River Delta. In the future, Shanghai’s outward railway transportation capacity is likely to expand along the Shanghai-Nanjing and Shanghai-Hangzhou corridors. 90 Measure the right angle, expand to 180 The railway network allows travel from the north to Nantong and from the south to Ningbo, with connections also available to Huzhou along the way. As a megacity, Shanghai is gradually relocating its non-core functions. Thanks to the high-speed rail network, Shanghai’s “backyard” has expanded, enabling more cities in the Yangtze River Delta to develop their tourism industries and improve residents’ quality of life. Moreover, the high-speed rail network plays a vital role in safeguarding people’s livelihoods: northern Jiangsu and regions like Huzhou have long served as key supply bases for vegetables, meat, and poultry to Shanghai. With the future opening of the Shanghai-Nantong and Shanghai-Suzhou-Huzhou railways, transportation between markets and production areas will become even more convenient.

As for industrial layout, it is naturally guided by the forces of the market itself. However, on an even more densely interconnected high-speed rail network, government departments still have much to do. Even more important than infrastructure connectivity—such as high-speed rail—is the institutional-level integration of the Yangtze River Delta in areas like ecological conservation and technological innovation. Experts from the Tsinghua Yangtze River Delta Research Institute also believe that today’s integrated development of the Yangtze River Delta should, on the basis of highly convenient transportation, enable localities to optimize the allocation of scientific and technological resources, accelerate the commercialization of research findings, and collaboratively build a regional innovation ecosystem.
