Evaluation of Port Logistics Efficiency and Analysis of Influencing Factors

Abstract

This paper constructs a port logistics input-output index system of Chongqing port, and analyzes the port logistics efficiency and influencing factors of Chongqing port using DEA-BCC and Tobit models. The results show that the overall port logistics efficiency of Chongqing port shows an incremental increase due to the continuous improvement of pure technical efficiency and scale efficiency. Port logistics efficiency has reached DEA effective and accompanied by fluctuation in recent years. The study shows that port city GDP negatively affects technical efficiency and scale efficiency. Unit port berth output positively affects technical efficiency and pure technical efficiency. The level of urbanization positively affects technical efficiency and scale efficiency, while population size positively affects scale efficiency only. Road freight volume and rail freight volume do not have an impact on port logistics efficiency.
