A New Global Narrative of Urban-Rural Integration: How the Yangtze River Economic Belt City Cluster Reshapes Spatial Justice

A New Global Narrative of Urban-Rural Integration: How the Urban Agglomerations in the Yangtze River Economic Belt Reshape Spatial Justice

In an era where globalization is receding and regionalization is reviving, the relationship between city and countryside is no longer a simple one of subordination and dependence, but has become a key yardstick for measuring a country's governance capacity, spatial justice, and long-term competitiveness. The evolution of urban-rural integration across the three major urban agglomerations of China's Yangtze River Economic Belt—the Yangtze River Delta, the Middle Reaches of the Yangtze River, and the Chengdu-Chongqing region—over the past decade offers a globally significant case for study. It is not merely a partial adjustment in regional economic geography, but also a reflection of institutional innovation and path choices made by developing countries as they juggle the interwoven tasks of industrialization, urbanization, and agricultural modernization.

I. From "Dual Opposition" to "Symbiotic Integration": A Shift in Spatial Philosophy

For a long time, the urban-rural dual structure has been regarded as a common governance challenge facing developing countries. In the early stages of reform and opening up, China experienced a phased arrangement in which rural areas supported cities and agriculture supported industry. However, the resulting urban-rural gap, one-way flow of factors, and imbalance in public services became potential risks to social stability. In recent years, with the completion of poverty alleviation and the advancement of the rural revitalization strategy, urban-rural relations have entered a new historical stage.

As a golden waterway spanning China's eastern, central, and western regions, the Yangtze River Economic Belt's urban agglomerations inherently embody the complex proposition of urban-rural integration in their spatial structure. The Yangtze River Delta, relying on its dense urban network and advanced manufacturing base, continues to lead in urban-rural integration development; the urban agglomerations in the Middle Reaches of the Yangtze River, benefiting from industrial transfer and the Rise of Central China policy, are showing a catching-up trend; and the Chengdu-Chongqing urban agglomeration, located in the western interior and affected by geographical conditions, economic foundations, and population distribution, lags relatively behind in urban-rural integration. This gradient difference is not simply a "development gap," but the product of the combined effects of different development stages, different resource endowments, and different governance models.

II. Structural Reality Revealed by Data: Imbalance within Agglomeration

A quantitative study based on data from 2010 to 2019 shows that the overall level of urban-rural integration development across the three major urban agglomerations of the Yangtze River Economic Belt has been on the rise, but the Chengdu-Chongqing urban agglomeration is significantly lower than the Yangtze River Delta and the Middle Reaches of the Yangtze River. In terms of spatial distribution, high-value areas are concentrated in the east and north, while low-value areas are concentrated in the west and south, showing an obvious agglomeration effect. This finding is highly consistent with the academic consensus that China's urban-rural integration is "high in the east and low in the west," but at the scale of urban agglomerations, this agglomeration effect reveals deeper structural issues.

The high level of integration in the Yangtze River Delta stems not only from the radiation and driving force of central cities such as Shanghai, Hangzhou, and Nanjing, but also from the deep nesting of urban and rural areas along the industrial chain, innovation chain, and public service chain. In contrast, although the Chengdu-Chongqing urban agglomeration has two national central cities, Chengdu and Chongqing, the vast counties and rural areas remain relatively marginalized, forming a "core-periphery" gradient pattern. This pattern cannot be changed overnight through policy stimulus; it requires systematic spatial reconstruction starting from underlying institutions such as infrastructure connectivity, market-based allocation of factors, and equalization of basic public services.### III. Rethinking the Driving Mechanism: Single Factors Ineffective, Interaction Effects Dominate

The research also finds that the improvement of urban-rural integration is not determined by a single factor. Indicators such as the proportion of non-agricultural population, per capita cultivated land area, and industrial structure have limited explanatory power when acting alone, but their interaction effects are remarkably significant. This conclusion has important policy implications: past approaches that relied on single-dimensional policy tools—such as simply increasing the rural-to-urban transfer population, adjusting cultivated land quotas, or promoting industrialization—can no longer cope with the complexity of urban-rural relations.

Of particular note, the volatility of the industrial structure variable reflects the profound impact of China's economic transformation on urban-rural integration. During the transition from manufacturing-led to service-led growth in the eastern coastal regions, factor flows between urban and rural areas have taken on new characteristics: while capital and talent concentrate in cities, ecological value, cultural value, and leisure demand flow back to the countryside. This budding "counter-urbanization" is not simply a reverse flow of population, but a two-way movement driven by both urban functional upgrading and rural value reassessment.

IV. China's Path in a Global Comparative Perspective

If we place the urban-rural integration practices of China's city clusters in a global perspective, we can see that they are fundamentally different from the post-war "urban-rural integration" path of developed countries. After achieving high levels of urbanization, European and American countries saw urban-rural relations evolve into a cycle of "urban diseases" and "rural decline," often relying on welfare policies and regional funds for ex-post adjustment. In contrast, China's urban-rural integration is being advanced simultaneously while urbanization is still incomplete—a "parallel" modernization strategy.

The uniqueness of this strategy lies in its attempt to avoid Latin American-style over-urbanization and hollowing-out, and it also differs from the "metropolis-first" polarization model of other East Asian economies. The case of the Yangtze River Economic Belt shows that city clusters can serve as spatial vehicles for urban-rural integration—connecting small and medium-sized cities and villages through infrastructure networks, revitalizing county economies through industrial chain division of labor, and balancing upstream and downstream through ecological compensation mechanisms. Of course, this path still faces enormous challenges, particularly the sustainability of urban-rural integration in the western region and how to maintain basic public service provision against the backdrop of population outflow.

V. Future-Oriented City Cluster Strategy: From Spatial Expansion to Quality Improvement

Looking ahead to the next decade, global urban competition will no longer be merely a competition of economic scale, but also a competition of spatial quality, governance capacity, and inclusiveness. For the Yangtze River Economic Belt city clusters to become a demonstration zone for new-style urbanization in the global sense, they need to transcend the traditional "core-periphery" mindset and establish a polycentric, grid-based, and ecological spatial structure. Urban-rural integration should not be seen as a "gift" from cities to rural areas, but rather as a symbiotic process in which urban and rural areas serve as resources and markets for each other.In terms of policy, more attention should be paid to the systematic integration of interactive factors—for example, coordinating the design of land system reform, household registration system reform, and fiscal transfer payment mechanisms to enable the bidirectional flow of labor, capital, land, data, and other factors between urban and rural areas. At the same time, digital technology should be fully utilized to reduce spatial-temporal friction, allowing remote villages to access urban production and service networks. Global experience has shown that urbanization without the support of urban-rural integration is fragile, just as modernization without the support of rural prosperity is unsustainable.

The story of the Yangtze River Economic Belt is a long-term experiment in spatial justice. It reminds us that an urban agglomeration is not merely an economic-geographic concept, but also a political-social contract—one that promises every resident, whether in an urban core or a remote countryside, the dignity and possibilities of development.
