AB - This study empirically investigates the impact of changes in urban spatial centrality on greenhouse gas (GHG) emissions. Focusing on 20 cities and districts (si/gun/gu) within Gyeonggi Province, the study quantifies the shift from monocentric to polycentric structures by analyzing the distributional changes in centrality between 2010 and 2020. Centrality is measured using spatial autocorrelation indices-LISA, Getis-Ord G, G*, and Geary’s C-based on the distribution of employment.
A spatial panel regression model, which accounts for both spatial interactions and temporal dynamics, is employed as the main analytical framework. In addition, scatterplot analyses are conducted to examine regional heterogeneity in responses. The results indicate that a higher degree of polycentricity is generally associated with an increase in Scope 1 direct GHG emissions. However, certain regions show a decline in emissions despite strengthened centrality, suggesting that changes in urban spatial structure do not yield uniform environmental effects across all areas. This highlights the contextual role of factors such as transportation infrastructure and industrial location as key moderating variables. By integrating spatial and temporal perspectives in the analysis of urban centrality, this study underscores the need for region-specific carbon reduction strategies tailored to urban structural dynamics.
