Digital Technology–Enabled Intelligent Upgrading of Logistics Services at Dalian Port from the Perspective of Smart Ports

Dalian Port’s logistics services face low efficiency, poor coordination, and limited value-added services. From a smart port perspective, this study proposes a "three-layer architecture and four-chain collaboration" framework enabled by digital technologies. Multi-scenario simulations show that digital empowerment reduces vessel turnaround time by 33%, increases quay crane efficiency by 39%, cuts per-container logistics costs by 18%, and raises the comprehensive intelligence index from 52.0 to 90.6. Practical countermeasures are provided for Dalian Port and similar ports.
