摘　　要：将数据包络分析(DEA)和Malmquist生产率指数理论相结合,运用到公路运输系统适应性分析中,针对公路运输系统自身特点,通过建立DEA—一致Malmquist模型,提出公路运输系统适应性分析体系,对比和分析公路运输系统与区域经济、人口、资源等外部因素间的适应性,并通过实例对模型进行验证。This paper integrates DEA and Malmquist theory to explore the adaptability of highway transportation system. According to the unique features of highway transportation system, we build a DEA-identical Malmquist Model and a research framework for analyzing the adaptability of highway transportation system and compare the adaptabilities of highway transportation system to external factors, such as regional economy, population, resources. Finally, we verify the validity of the model through an example.
