【摘要】：交通运输行业是国民经济的命脉产业,其投入产出效率的改进和提高事关整个国民经济的顺利运行。利用DEA-Malmquist指数,从技术效率变化、纯技术效率变化、规模效率变化、技术进步等指标入手,实证分析2010—2016年我国交通运输行业80家上市企业全要素生产率发现,2010—2016年我国交通运输行业平均全要素生产率整体呈下降趋势,但幅度较小,且不同年份下降的原因不同。其中,港口、公交、航空运输、航海运输、机场、铁路运输、物流七个类别的企业尽管并非全部下降,但均存在波动。整个交通运输行业投入产出效率的提高需要社会以及企业自身多方面的努力。对政府和整个行业而言,要更多关注民营企业和中小企业,为它们提供政策扶持与资金支持,通过创造平等而自由的竞争环境来促进交通运输行业健康发展;对交通运输企业而言,要持续进行技术投入,硬件软件两手抓,在确保技术效率进步的同时实现规模扩大与规模效率提高,达到技术投入与管理水平的双赢。
[Abstract]:The transportation industry is the lifeblood of the national economy industry, the improvement of the input-output efficiency and improve the whole national economy running smoothly. By using the DEA-Malmquist index, from the change of technical efficiency, pure technical efficiency change and scale efficiency change, technological progress and other indicators of the empirical analysis, the total factor productivity from 2010 to 2016, China's transportation industry, 80 listed companies found that from 2010 to 2016, China's transportation industry average TFP overall downward trend, but to a lesser extent, the reason and the decline of different in different years.
