This article selects 31 provinces (municipalities and autonomous regions) in China as the study units, and uses the DEA model to analyze the comprehensive transportation efficiency and its temporal evolution characteristics in China over the period of 1988-2011. The results indicate that the integrated transport efficiency is relatively low, and diminishing from the east and west to the central. From the point of view of decomposition efficiency, the integrated transport technical efficiency is relatively low, but the scale efficiency is very high. The spatio-temporal evolution of integrated transport efficiency was determined by scale efficiency. Most provinces have transferred from the stage of increasing return to scale to the stage of decreased return to scale, which means further improvement of integrated transport efficiency will be hampered by too much input of resources. Our findings imply that the development of transport efficiency in the future should be improved by restructuring and optimizing the existing transport resources, especially to the necessity of improving technical efficiency for the improvement of integrated transport efficiency.
Key words: integrated transport efficiency; technical efficiency; scale efficiency; DEA; China
