SPATIAL DISTRIBUTION CHARACTERISTICS AND DIFFERENCE ANALYSIS OF URBAN SERVICE FACILITIES IN NORTH CHINA

Abstract

This study conducts a comparative analysis of urban service facilities in Changchun and Hohhot by constructing a service density index, applying the coefficient of variation method, and utilizing the Spatial Lag Model (SLM). Results indicate that Changchun achieves a higher overall service level (CV=347.64) compared to Hohhot (CV=307.55), with significant disparities across seven domains, most notably transportation infrastructure. SLM regression reveals that Changchun exhibits stronger spatial integration and spillover effects while Hohhot demonstrates localized competition and fragmented service allocation patterns. Partial differential decomposition further confirms these divergent spatial dependency structures. This research establishes a replicable quantitative framework for cross-city comparative analysis, offering valuable theoretical support and evidence-based insights for optimizing urban resource allocation, informing differentiated planning strategies, and enhancing urban resilience in northern China.
