Abstract：Addressing the unclear key factors and mechanisms influencing regional freight structure optimization,this study proposes a systematic research approach.Firstly,leveraging the Latent Dirich-let Allocation(LDA)topic model,eight pivotal factors are systematically extracted and identified:socioeconomic development level,industrial structure,natural geographical conditions,energy struc-ture,environmental awareness,techno-economic attributes,scientific and technological progress,and transportation industry policies.Secondly,based on research hypotheses,a Structural Equation Model(SEM)is formulated to analyze the effects and interrelationships of these factors on regional freight structure.Finally,elasticity analysis is introduced to quantify the contribution of each factor to freight structure adjustment.The results indicate that all eight factors significantly promote regional freight structure adjustment,with varying degrees of impact and elasticity across regions.The eastern region should focus on optimizing industrial structure,leveraging geographical advantages,enhancing environmental awareness,and promoting green freight technologies and policy guidance to build an efficient and green freight system.The central region needs to optimize geographical conditions,advance transportation infrastructure,improve freight network connectivity and efficiency,and strengthen investment guidance to enhance techno-economic characteristics and facilitate freight struc-ture optimization.The western region should accelerate the integration of ecological protection and technological development,emphasize techno-economic improvements,promote freight technology innovation,and optimize costs to drive green and innovative freight structure development.At the overall level,efforts should strengthen the dynamic alignment of industrial structure and techno-economic characteristics,improve policy precision and coordination,and promote innovation and upgrading of transportation modes and systems.
