摘　　要：为科学测算和提高山东省综合交通运输效率,基于RAM模型,纳入人口规模、经济水平和城市化水平作为新投入参量,人口与经济协调发展总值作为期望产出,利用熵值法与RAM模型测算综合交通运输效率,并使用灰色关联度分析与岭回归分析研究各指标对山东省综合交通运输效率的影响。结果表明:新构建的RAM模型下整体综合交通运输效率呈现出稳健的增长态势;经济水平与人口与经济协调发展总值是综合交通运输效率的重要影响因素。In order to scientifically calculate and improve the economic efficiency of transportation in Shandong Province,based on RAM model,population size,economic level and urbanization level were included as new input parameters,and the total value of coordinated development of population and economy was taken as the expected output.The entropy method and RAM model are used to measure the comprehensive transportation efficiency,and the influence of each index on the comprehensive transportation economic efficiency of Shandong Province is studied by using Grey relational degree analysis.The results show that the overall integrated transportation economic efficiency presents a steady growth trend under the newly constructed RAM model.Economic level and the total value of coordinated development of population and economy are important factors affecting the economic efficiency of comprehensive transportation.
