What is New Economic Geography?
New Economic Geography (NEG) is a formal economic framework modeling how increasing returns, transport costs, and market structures drive agglomeration, urban systems, and trade patterns in regional development.
NEG, developed by Paul Krugman in the 1990s, uses core-periphery models to explain spatial concentration of economic activity (Krugman, 1991). Over 5,000 papers apply NEG to urbanization and regional inequalities. Key extensions analyze migration and policy interventions in spatial economies.
Why It Matters
NEG models persistent regional disparities, as seen in China's Major Function Oriented Zones reshaping development patterns (Fan et al., 2012, 121 citations). They guide urban planning and trade policies, informing EU cohesion funds and China's spatial regulation. Migration analyses link skilled worker flows to competitiveness (Oliinyk et al., 2021, 141 citations), aiding national growth strategies.
Key Research Challenges
Modeling Transport Costs
NEG relies on iceberg transport costs, which oversimplify real logistics and infrastructure effects. Empirical calibration remains difficult across scales (Fan et al., 2012). Recent work seeks data-driven alternatives using GIS integration.
Incorporating Migration Dynamics
Standard NEG underplays skilled migration's role in agglomeration, as highlighted in competitiveness studies (Oliinyk et al., 2021). Demographic transitions add volatility (Zakharov, 2008). Models need better human capital linkages.
Policy Evaluation Robustness
NEG simulations predict agglomeration but struggle with counterfactual policy impacts amid shocks like COVID-19 migration shifts (Stawarz et al., 2022). Validation requires longitudinal data. Spatial heterogeneity challenges uniform zoning (Li and Liu, 2021).

How PapersFlow Helps You Research New Economic Geography
Discover & Search
Research Agent uses searchPapers('New Economic Geography agglomeration models') to retrieve Fan et al. (2012) on China's spatial regulation, then citationGraph reveals 121 downstream applications. exaSearch uncovers migration extensions like Oliinyk et al. (2021), while findSimilarPapers expands to urban prospects (Bocquier, 2005).
Analyze & Verify
Analysis Agent applies readPaperContent on Bocquier (2005) to extract urbanization projections, then runPythonAnalysis regresses migration data against NEG variables using pandas for spatial autocorrelation tests. verifyResponse with CoVe cross-checks claims against 1764 citations; GRADE scores evidence strength for policy robustness.
Synthesize & Write
Synthesis Agent detects gaps in NEG-migration links via contradiction flagging across Zakharov (2008) and Oliinyk (2021), generating exportMermaid diagrams of core-periphery flows. Writing Agent uses latexEditText for model equations, latexSyncCitations for 50+ refs, and latexCompile for publication-ready reports.
Use Cases
"Run spatial regression on NEG factors from Chinese digital economy papers"
Research Agent → searchPapers → Analysis Agent → runPythonAnalysis (pandas spatial lag model on Li and Liu 2021 data) → matplotlib heatmap output showing agglomeration drivers.
"Draft LaTeX section on NEG policy zones with citations"
Synthesis Agent → gap detection → Writing Agent → latexEditText (insert Fan et al. 2012 eqs) → latexSyncCitations → latexCompile → PDF with synced 121-citation bibliography.
"Find code for NEG simulation models in migration papers"
Research Agent → paperExtractUrls (Oliinyk et al. 2021) → Code Discovery → paperFindGithubRepo → githubRepoInspect → replicated Python NEG-mobility simulator.
Automated Workflows
Deep Research workflow scans 50+ NEG papers via citationGraph on Krugman extensions, producing structured report with migration trends (Bocquier, 2005). DeepScan's 7-step chain verifies agglomeration claims in Fan et al. (2012) using CoVe checkpoints and runPythonAnalysis. Theorizer generates hypotheses linking NEG to skilled migration drivers (Kwiliński et al., 2022).
Frequently Asked Questions
What defines New Economic Geography?
NEG models agglomeration via increasing returns, transport costs, and monopolistic competition, explaining why economic activity concentrates spatially (Krugman, 1991).
What are core NEG methods?
Core-periphery models use Dixit-Stiglitz demand and iceberg transport costs; extensions apply spatial econometrics and simulations for policy analysis (Fan et al., 2012).
What are key NEG papers?
Foundational: Bocquier (2005, 1764 citations) on urbanization; Fan et al. (2012, 121 citations) on zoning. Recent: Oliinyk et al. (2021, 141 citations) on migration.
What open problems exist in NEG?
Integrating dynamic migration (Zakharov, 2008), empirical transport calibration (Li and Liu, 2021), and shock resilience like COVID effects (Stawarz et al., 2022).
