Abstract：Transportation industry is the critical industry of national economy；the improvement of input –output efficiency of this industry will have the important impact on the operation of national economy. In this paper，the Dea- malmquist index is used to analyze the change of total factor productivity (TFP) of 80 listed transportation companies in China from 2010 to 2016；and the authors further analyze enterprises in such 7 categories as ports，public transportation，aviation，shipping，airport，rail transportation，and logistics and draw the following conclusions：from 2010 to 2016，the overall TFP in the transportation industry were slightly declining，and the reasons for the decline in different years were different. Not the TFP of all the enterprises in the 7 categories were declining，but they were fluctuating over these years. The improvement of the overall input- output efficiency of this industry will depend on the effort of the whole society and the related enterprises. The government and the industry should pay more attention to the development of private enterprises，especially the SMEs，provide them with more policy and capital support， and promote the healthy development of transportation industry by creating the fair and free competition environment；the transportation industry should sustainably increase investment in terms of technology，realize the expansion of scale and the growth of scale economies，and realize the win-win situation in terms of technological investment and management level.
