Theoretical Understanding and Practical Difficulties of Freight Structure Adjustment in China
To explore the theoretical origins of freight structure adjustment and understand the development and evolution patterns of freight structure,this paper analyzed the theoretical sources and development law of freight structure adjustment,summarized the challenges faced by freight structure adjustment in China,and proposed several key work in freight structure adjustment.The research finds that supply and demand transactions determine the formation of freight structure,and the main focus of freight structure adjustment work lies on the supply side.Road transportation has the highest proportion of freight transportation,and the long-term upward trend in the proportion of road freight is a global phenomenon that is difficult to change.Moreover,rail-based and water-based intermodal transportation has advantages in specific segments of the freight market.Freight structure adjustment in China faces challenges such as a high proportion of road freight,relatively lagging development of intermodal transportation,and insufficient adaptation to transportation organization methods.Relevant policies should focus on balancing overall and local relationships,coordinating primary and auxiliary relationships,and utilizing push-pull relationships,so as to promote transportation structure optimization and adjustment through the development of intermodal transportation.
