Urban and Regional Economics

Urban and regional economics examines how populations, firms and public authorities interact across space to shape patterns of growth, inequality and sustainability. At its heart lie the forces of agglomeration—the productivity gains that accrue when firms and workers concentrate—and dispersion, which can arise from rising land rents, congestion and commuting costs. Models integrate transport costs, housing markets and local amenity levels to explain why some cities thrive while others stagnate, and how infrastructure investments or policy interventions alter regional trajectories. Recent advances have deepened our understanding of spatial spill-overs, from knowledge diffusion along high-speed rail corridors to the redistribution of factor flows in mature megaregions. Empirical techniques range from multi-regional input-output tables and spatial econometrics to quasi-experimental designs capturing land-value uplift or well-being impacts of commuting. Policy applications include transit-oriented development, value-capture mechanisms, metropolitan governance arrangements and regional devolution strategies aimed at balanced growth. By blending theory with granular data, urban and regional economics provides a rigorous framework for city planners, transport authorities and economic strategists confronting the twin challenges of competitiveness and inclusion.

Analysis of the Pan Pearl River Delta illustrates how transportation networks mediate the agglomeration and diffusion of production factors across major Chinese cities. Using social network methods alongside panel econometric models, researchers show that core hubs such as Guangzhou and Shenzhen stabilise growth in their round–trip hinterlands, while peripheral nodes exhibit differentiated contributions to regional gross domestic product and environmental externalities. The study highlights the value of small-world network structures and calls for calibrated local policies that “adjust measures to local conditions” to enhance coordinated low-carbon development.

Satellite remote-sensing and spatial econometric analysis of 223 high-speed rail new towns in China between 2011 and 2021 reveal a narrowing of development disparities and a sustained positive effect on urban sustainable development. Central new towns yield stronger improvements in land‐use efficiency and resource productivity than peripheral ones, underscoring the need for integrated planning of stations, public services and environmental safeguards to ensure these nodes contribute to more resilient metropolitan regions.

Technical terms

Agglomeration economies: Productivity gains that arise when firms and workers locate near one another, facilitating knowledge spill-overs, specialised inputs and large local markets.

Accessibility: A measure of how easily destinations or economic opportunities can be reached, taking account of transport modes, network speed and distance.

Spatial spill-over: The indirect effect of an economic shock or policy in one area on neighbouring regions, transmitted via trade, migration or commuting links.

Small-world network: A network topology characterised by high clustering and short path lengths between nodes, which supports efficient diffusion of information or resources.

Value capture: Financing mechanisms that recover a share of land-value increments generated by public infrastructure investments to fund further development.

Quasi-experimental design: An empirical strategy that exploits natural variations or policy changes to infer causal impacts in the absence of random assignment.
