Spatial Spillover Effects of Urban Agglomeration on Road Network with Industrial Co-Agglomeration
Abstract
Urban agglomerations are pivotal to industrial co-agglomeration, underscoring the significance of efficient road networks and economic growth. This study examines the spatial spillover effects of infrastructure resilience on industrial co-agglomeration at varying mobility levels in the Guanzhong Plain, China, utilizing origin–destination (OD) and traffic flow networks in highways. Guanzhong contributes 88% of the GDP and covers 25% of land, and its prime location was the initial point of the ancient Silk Road in China. Our analysis yields several novel insights. Industrial co-agglomeration displays negative (from −0.175 to −0.207) spatial autocorrelation among neighboring regions, indicating pronounced regional competition. In the OD network, both connectivity and efficiency resilience positively influence (0.189 and 0.397) local industrial co-agglomeration but adversely affect connected regions (−0.383 and –0.915), with the impact of efficiency resilience increasing at higher mobility levels. The highway network intensifies spatial spillover effects and exacerbates competition and disparities in industrial co-agglomeration across counties. The network resilience of highways exhibits distinct spatial distribution patterns, with critical nodes concentrated along the central economic axis of the urban agglomeration. Furthermore, the influence of highway network resilience on industrial co-agglomeration varies between OD and traffic flow networks, which implies different impacts under some mobility scenarios. These findings advance our understanding of the intricate relationship between road networks and industrial co-agglomeration, offering valuable insights for crafting balanced regional development strategies and informing transportation planning to foster local and regional coordination.
