AO BRIEF (Statistical) — Chengdu–Chongqing–Xi’an Macro-Region, China
-
Inland western China growth belt linking Chengdu (Sichuan Basin west), Chongqing (upper Yangtze metropolis), and Xi’an (Guanzhong Plain).
-
Functional triangle distance scale: Chengdu–Chongqing ≈ 300 km; Chongqing–Xi’an ≈ 650 km; Chengdu–Xi’an ≈ 700 km (corridor routing dependent).

Mobility Impact |
| Sichuan Basin (Chengdu) |
450–750 m |
Alluvial plain, low relief |
High road/rail density, logistics-friendly |
| Chongqing Uplands |
200–900 m (urban core on terraces) |
Deeply dissected hills, river gorges |
Tunnel/bridge reliance, chokepoint risk |
| Qinling–Daba Approaches (to Xi’an) |
1,000–2,500 m passes |
Mountain corridors |
Limited parallel routes |
| Guanzhong Plain (Xi’an) |
350–600 m |
Broad basin/valley floor |
Strong surface mobility |
Transport Infrastructure (High-Level Counts)
Expressways (G-series + provincial)
-
Chengdu Basin network density: among the highest in western China; multiple ring roads (≥3) plus radial G-routes.
-
Chongqing: >20 major Yangtze/Jialing river bridges within metro area; complex stacked interchanges.
-
Northbound corridors toward Xi’an: 2–3 primary expressway axes through mountain tunnel systems (weather/landslide sensitive).
High-Speed Rail (HSR)
-
Chengdu–Chongqing HSR travel time ≈ 1–1.5 hrs.
-
Xi’an connected to both via national HSR grid; Xi’an–Chengdu HSR crosses Qinling tunnels.
-
Stations per metro: typically 4–8 major HSR nodes in wider municipal footprint.
Airports

Major Airport System |
Notes |
| Chengdu |
Dual-airport system |
Western aviation hub; intercontinental reach |
| Chongqing |
Major single hub |
Central-west air logistics pivot |
| Xi’an |
Primary northwest hub |
Strong military/civil aviation history |
Inland River Transport
-
Chongqing is the upper Yangtze’s largest inland port city.
-
River class supports 10,000-ton barge convoys downstream seasonally (water level dependent).

Risk & Constraint Statistics (Qualitative Frequency)
-
Seismic exposure: Western Sichuan margin — moderate to high regional hazard.
-
Flood risk (river stage): Seasonal operational impacts in Chongqing riverfront zones.
-
Fog/haze days: Elevated winter frequency affecting aviation reliability.
-
Landslide corridors: Mountain expressways toward Xi’an — localized closure risk.
Strategic Transport Ratios
-
Intra-basin redundancy (Chengdu–Chongqing): High.
-
Inter-basin redundancy (to Xi’an): Moderate–low.
-
Multimodal diversity index: Chongqing highest (road+rail+river+air).
Command Takeaways (Data-Driven)
-
Population mass + industry density make this one of China’s largest inland economic clusters (~66M people).
-
Chongqing = multimodal freight pivot but highest terrain friction.
-
Chengdu = logistics geometry advantage (flat basin).
-
Xi’an = northern corridor anchor with strong rail/air orientation.
-
Mobility bottlenecks concentrate in mountain tunnel belts and major river bridges.
