Abstract:A networked territorial spatial pattern, centered around major strategic corridors, plays a crucial role in supporting the construction of the new dual-circulation development pattern. The “Two Horizontals and Three Verticals” major strategic corridors that have been formed can effectively promote the concentration of socio-economic factors in major urban agglomerations. However, there exists a mismatch between the north-south vertical strategic corridors and the east-west socio-economic linkages and transportation corridors. Besides, the existing strategic corridors lack sufficient horizontal support for the Beijing-Tianjin-Hebei urban agglomeration, and the land and sea corridors exhibit weak horizontal driving effect and insufficient connection with external corridors. “Three Horizontals and Three Verticals” major strategic corridors should be constructed to realize the integration of domestic strategic corridors and external corridors, to utilize coastal city clusters as a driving force for central and western China, and to support the optimization of the functional zoning strategy.
